DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION

Referring to the drawings, wherein like reference numbers refer to like elements, the principles of the present application are illustrated as being implemented in a suitable computing environment. The following description is based on illustrated embodiments of the application and should not be taken as limiting the application with respect to other embodiments that are not detailed herein.

The term "module" as used herein may be considered a software object executing on the computing system. The various components, modules, engines, and services described herein may be viewed as objects implemented on the computing system. The apparatus and method described herein are preferably implemented in software, but may also be implemented in hardware, and are within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. As shown in fig. 1, the electronic device includes an application processor, a coprocessor and a display screen, where the application processor and the coprocessor are both electrically connected to the display screen, and power consumption of the coprocessor during operation is less than that of the application processor during operation. The coprocessor can control the updating and displaying of information such as time, date, weather, calendar and the like, can also control the display of the icon of the shortcut tool on a screen-off display interface, and can also support the running of some lightweight application programs such as an electronic book, a compass, a calculator, a handwriting board and the like. When the coprocessor is in a working state, the application processor is in a dormant state, so that the power consumption of the electronic equipment is reduced by the coprocessor with lower power consumption.

The coprocessor and the application processor can be integrated with one or more of a central Processing Unit (GPU), a modem and the like. Wherein, the CPU mainly processes an operating system, a user interface, an application program and the like; the GPU is used for rendering and drawing the content required to be displayed by the display screen; the modem is used to handle wireless communications. It is understood that the modem may be implemented by a single chip without being integrated into the application processor and the coprocessor.

The coprocessor and the application processor can be connected through a communication bus. The communication bus may be an I2C (Inter-Integrated Circuit) bus or an SPI (Serial Peripheral Interface) bus. In other embodiments, other formats of communication buses may be used, and are not specifically limited herein.

The display screen may include a glass cover plate, a touch sensor, and a display assembly. Wherein the touch sensor can be integrated under a glass cover plate, the glass cover plate being used to protect the touch sensor and the display assembly. Optionally, the display component may include pixel points. The electronic equipment can independently emit light through the pixel points so as to display a corresponding image on the display screen.

Referring to fig. 2, fig. 2 is a second structural schematic diagram of an electronic device according to an embodiment of the present disclosure.

The application processor may be integrated in the first control Chip, and the first control Chip may be used as a main control SOC (System on Chip) of the electronic device. In some embodiments, the electronic device further comprises a first memory co-integrated with the application processor in the first control chip. The coprocessor can be integrated in the second control chip, so that the power consumption of the second control chip in the working state is far smaller than that of the first control chip in the working state. In some embodiments, the electronic device further comprises a second memory, the memory capacity of the second memory is smaller than that of the first memory, and the second memory and the coprocessor are integrated into a second control chip together.

The first control chip runs an application arranged in a first operating system based on the first operating system; the second control chip runs the application arranged in the second operating system based on the second operating system, wherein the application in the second operating system can comprise an electronic book application, a game application, a weather application, a compass application and the like. The second control chip runs an electronic book application, a game application, a weather application, and a compass application based on the second operating system.

Wherein the first operating system and the second operating system are different operating systems, and the resources required by the second operating system when running are less than the resources required by the first operating system when running. The resource may be a cache space, an operation frequency, a required power amount, and the like. For example, the first operating system may be an android operating system, a Linux operating system, a Windows operating system, or an ios operating system, and the second operating system may be a real-time operating system. The electronic device 100 may run the first operating system or the second operating system. It should be noted that the first operating system and the second operating system are independent operating systems.

The first control chip comprises a communication port 10a and a display control port 10 b. The second control chip comprises a communication port 20a and a display control port 20 b. The communication port 20a of the second control chip is electrically connected with the communication port 10a of the first control chip to realize the communication between the second control chip and the first control chip. The communication port 20a may be an SPISLV interface and an I2CSLV interface of the second control chip. The communication port 10a may be a Mailbox interface of the first control chip.

In some embodiments, the electronic device further comprises a switching module comprising a data input port 30a, a data input port 30b, a switching control port 30c, and a data output port 30 d. The data input port 30a is electrically connected to the display control port 10b of the first control chip to enable communication between the first control chip and the switching module, which can receive the image data generated by the first control chip through the data input port 30 a. And the switching module can be electrically connected with the display screen through the data output port 30d, so that the switching module can send the received image data generated by the first control chip to the display screen through the data output port 30 d. Therefore, the image data generated by the first control chip is sent to the display screen through the switching module so as to control the display screen to display the corresponding image.

The data input port 30b is electrically connected to the display control port 20b of the second control chip to enable communication between the second control chip and the switching module, which can receive image data generated by the second control chip through the data input port 30 b. And the switching module can be electrically connected with the display screen through the data output port 30d, so that the switching module can send the received image data generated by the second control chip to the display screen through the data output port 30 d. And sending the image data generated by the second control chip to the display screen through the switching module so as to control the display screen to display the corresponding image.

The switching module is specifically used for switching a display data conduction path of the display screen between the first control chip and the second control chip. For example, case A: when the first control chip is in a working state and the second control chip is in a dormant state, the display data of the first control chip is input to the display screen through the switching module to be displayed and controlled. Case B: when the first control chip detects a starting instruction of a target application such as a handwriting board application, the second control chip is awakened, and the first control chip enters a dormant state. After the second control chip is awakened, the switching module is controlled to execute switching operation, the switching module switches the input source of the display data of the display screen from the first control chip to the second control chip, namely, the display data of the second control chip is input to the display screen through the switching module to be displayed and controlled. Case C: when the second control chip detects the awakening instruction of the first control chip, the second control chip awakens the first control chip, when the first control chip is awakened to enter a working state, if the first control chip needs to display information on the display screen, the second control chip controls the switching module to execute switching operation, and switching is performed to switch on display data output by the first control chip to the display screen for display control. After switching, the second control chip can be in a dormant state, namely, the second control chip returns to the situation A, and thus the switching control of the display screen is circularly realized.

In the above manner, the second control chip may further include a switching signal output port 20c, and the switching signal output port 20c is electrically connected to the switching control port 30c of the switching module, so that the second control chip may send the switching control signal to the switching module through the switching signal output port 20c and the switching control port 30c, so as to implement the switching of the switching module controlled by the second control chip, and the interface occupation of the first control chip may be saved in a hardware design level. It can be understood that, since the first control chip is a main control SOC chip in the electronic device, the main control SOC generally undertakes more functional control, and interface resources thereof are more tense. The second control chip outputs the switching control signal to control the switching of the switching module, so that an interface (such as a bus interface) of the main control SOC is not occupied, and the complexity of circuit design is reduced conveniently.

Referring to fig. 3, fig. 3 is a first flowchart illustrating a method for displaying an electronic book according to an embodiment of the present disclosure. The electronic device comprises an application processor and a coprocessor electrically connected with the application processor, and the power consumption of the coprocessor during operation is smaller than that of the application processor. Specifically, the method for displaying the electronic book may include the steps of:

in step S101, the application processor scans the electronic book to extract the content of the electronic book, and generates display data.

When the application processor detects an electronic book selection instruction input by a user, the application processor acquires the electronic book selected by the user and scans the electronic book to extract basic contents of the electronic book. The basic contents of the electronic book may include name information, author information, chapter information, directory information, word number information, and character information of the electronic book, etc. And processes the information to produce corresponding display data.

The electronic book selected by the user is the electronic book to be read by the user, so that after the electronic book is scanned, the generated display data can be stored into the second cache space corresponding to the application processor, so that the time required by loading the electronic book in the reading process of the user is reduced.

In some embodiments, the electronic device may be in a bright screen mode and may also be in an off screen Display (AOD) mode when the application processor scans the electronic book. The off-screen display mode refers to a display mode in which the electronic device displays information on the display screen in the off-screen mode. When the electronic equipment is in a bright screen mode and the application processor detects a selected instruction of the electronic book, the step that the application processor scans the electronic book to extract the content of the electronic book and generate display data is executed. And after the application processor sends the display data to the coprocessor, the application processor wakes up the coprocessor by processing, then the application processor enters a dormant state, and the electronic book application is run through the coprocessor, so that the power consumption of the electronic equipment is reduced.

When the electronic equipment is in a screen-off display mode, the application processor is in a dormant state, the coprocessor runs an electronic book application, and when the coprocessor detects a selected instruction of the electronic book, the coprocessor has a low processing speed when processing a preset touch operation because the frequency of the coprocessor is far less than that of the application processor, so that the coprocessor cannot rapidly scan and load the electronic book when facing the selected instruction of the electronic book. In addition, because the memory capacity of the first cache space corresponding to the coprocessor is much smaller than the memory capacity of the second cache space corresponding to the application processor, the first cache space cannot cache the memory size of the electronic book, and the loading of the electronic book fails.

Therefore, when the selected instruction of the electronic book is detected, the coprocessor needs to briefly wake up the application processor, send the selected instruction of the electronic book to the application processor, and execute the steps of scanning the electronic book by the application processor through the application processor to extract the content of the electronic book and generate the display data. At this time, after the coprocessor wakes up the application processing, the coprocessor and the application processor are both in a working state. And after the application processor sends the display data to the coprocessor, the application processor is immediately controlled to enter a dormant state, and the electronic book application is run through the coprocessor, so that the power consumption of the electronic equipment is reduced.

In step S102, the application processor sends the display data to the coprocessor, and the application processor enters a sleep state after the sending is completed.

The application processor can sequentially send the display data to the coprocessor through the mailbox interface of the first control chip, and after the display data are sent, the application processor is controlled to enter a dormant state, so that the operation of the electronic book application is controlled through the coprocessor.

As described above, since the memory capacity of the first cache space corresponding to the coprocessor is much smaller than the memory capacity of the second cache space corresponding to the application processor, the first cache space cannot normally cache the display data of the electronic book with a large memory requirement. Therefore, the application processor may determine the transmitted display data according to the size of the capacity of the first buffer space. For example, the memory requirement of the display data of the scanned electronic book is 20MB, and the memory capacity corresponding to the first buffer space is 2 MB. At this time, the application processor may send a portion of the display data (the memory requirement of the display data does not exceed 2MB) to the co-processor in the order of the display data.

In step S103, the coprocessor stores the display data in the corresponding first buffer space.

The coprocessor receives the display data, performs centralized typesetting processing on the display data to divide the display data into a plurality of pages, and stores the display data into a first cache space in the form of the pages, so that a user can conveniently display corresponding contents by using the complete pages when turning over the electronic book.

In step S104, the coprocessor loads the display data from the first buffer space to display the page of the display data.

After the coprocessor determines the page to be displayed, the target page corresponding to the page to be displayed can be acquired, and the display data of the target page is loaded from the first cache space so as to display the display data of the target page.

For example, when a user clicks an electronic book that is not referred to for viewing, and the coprocessor determines that a page to be displayed is a first page of the electronic book, the coprocessor loads display data corresponding to the first page from the first cache space, so that the first page of the electronic book is displayed on the display screen.

As can be seen from the above, the electronic book display method provided by this embodiment is applied to an electronic device, where the electronic device includes an application processor and a coprocessor electrically connected to the application processor, and power consumption of the coprocessor during operation is smaller than power consumption of the application processor during operation. The application processor scans the electronic book to extract the content of the electronic book and generates display data; the application processor sends the display data to the coprocessor, and the application processor enters a dormant state after the sending is finished; the coprocessor stores the display data into a corresponding first cache space; and the coprocessor loads the display data from the first cache space to display the page corresponding to the display data. After the application processor sends the display data of the electronic book to the coprocessor, the application processor is controlled to enter a dormant state, so that the electronic book application is run through the coprocessor with low power consumption, and the overall power consumption of the electronic equipment is reduced.

Referring to fig. 3, fig. 3 is a second flowchart illustrating a method for displaying an electronic book according to an embodiment of the present disclosure. The display method of the electronic book is applied to electronic equipment, the electronic equipment comprises an application processor and a coprocessor electrically connected with the application processor, the power consumption of the coprocessor during operation is smaller than that of the application processor, and the display method comprises the following steps:

in step S201, the application processor scans the electronic book to extract chapter information of the electronic book and text content corresponding to each chapter information, and respectively caches the chapter information and the text content corresponding to each chapter information in a second cache space corresponding to the application processor.

When the application processor detects an electronic book selection instruction input by a user, the application processor acquires the electronic book selected by the user and scans the electronic book to extract chapter information of the electronic book and character content corresponding to each chapter of information. The chapter information is a name of each chapter, such as a first chapter, a second chapter, and the like. The text content of the electronic book can be divided into a plurality of content blocks by taking chapter information as a unit for storage, wherein each content block comprises the chapter information and the text information corresponding to the chapter information.

In step S202, the application processor determines different text contents existing in the electronic book from all text contents in the second buffer space, and converts each different text content into display data in an image form.

The application processor scans all the text contents stored in the second cache space to determine different text contents existing in all the text contents of the electronic book, and then converts each different text content into display data in an image form. The application processor traverses each character content of the electronic book and deletes repeated character contents in the electronic book, thereby determining different character contents existing in the electronic book and converting the different character contents into display data in an image form.

For example, all the text contents of the electronic book are "true good weather today", and each text content obtained by scanning the electronic book is five text contents of "present", "day", "qi", "true" and "good". The application processor traverses each text content, deletes repeated text contents in the electronic book, such as the 2 nd text content of "day", and the obtained different text contents are four different text contents of "today", "day", "qi", "true" and "good", and the four different text contents of "today", "day", "qi", "true" and "good" are converted into display data in an image form.

The file format of the character image is a bitmap file, and the industrial processor can convert each different character content into a corresponding character image, so that the coprocessor does not need to be provided with a bitmap-vector diagram conversion module occupying a larger storage space, and the storage space of the coprocessor can be saved. In some embodiments, the text image is a 1-pixel depth (BPP) image.

In step S203, the application processor acquires a first number of chapter information from the second cache space, and acquires display data corresponding to each chapter information in the first number of chapter information. The first quantity is determined according to the capacity of the first cache space, and the first quantity is the maximum number of chapters of the first cache space capable of caching the electronic book. For example, the first buffer space can buffer the content of at most 10 chapters of the electronic book, and the first number is 10. Then, when the electronic book starts to be loaded, the application processor respectively obtains the chapter information corresponding to the electronic book as the text contents of chapters 1 to 10, and determines corresponding display data according to each text content to obtain the display data corresponding to each chapter information.

In step S204, the application processor sequentially sends the display data to the coprocessor, and the application processor enters a sleep state after the sending is completed.

The display data is sequentially sent to the coprocessor according to the corresponding chapter information, for example, the display data corresponding to chapters 1 to 10 are sequentially sent to the coprocessor according to the sequence of the chapter information from small to large, the application processor is controlled to enter a dormant state after the display data is sent, and the electronic book application is run through the coprocessor.

In step S205, the coprocessor divides the display data corresponding to each chapter of information into a plurality of pages according to the arrangement order of the display data, the first size information of the display data in the form of an image, and the display size information of the display screen of the electronic device, and stores the display data in the form of a page in the first cache space.

The coprocessor typesets the display data of each chapter according to the arrangement sequence of the display data, the first size information of the display data in the image form and the display size information of a display screen of the electronic equipment, so that the display data corresponding to each chapter is divided into a plurality of pages, and finally the display data is stored into a first cache space in the page form.

In step S206, the coprocessor determines a plurality of pages corresponding to each chapter information, and sequentially adds the chapter information and the pages corresponding to each chapter information to the chapter link table in the first cache space.

The coprocessor can sequentially add each chapter information and a plurality of pages corresponding to each chapter information to the chapter chain table according to the sequence of the chapter information from small to large. The chapter information corresponding to each page and the sequence information of each chapter information can be determined according to the chapter chain table.

In step S207, the coprocessor sequentially loads the display data corresponding to each page from the first buffer space, so as to sequentially display each page of the electronic book.

The coprocessor loads display data corresponding to each page in sequence from the first cache space so as to display the content of each page of the electronic book on the display screen in sequence.

In some embodiments, after step S207, the coprocessor may further receive a page turning instruction of the user, and control a page turning display function of the electronic book application according to the page turning instruction. The method comprises the following specific steps:

in step S208, when the coprocessor receives the page turning instruction, the coprocessor determines the target page corresponding to the page turning instruction based on the currently displayed page.

The coprocessor can also receive a page turning instruction of a user, and the coprocessor can determine a target page according to the currently displayed page based on the page turning instruction. For example, when the page turning instruction is to turn the page forward, the previous page of the currently displayed page is taken as the target page according to the page turning instruction.

In some embodiments, when the coprocessor receives the page turning instruction, the step of the coprocessor determining the target page corresponding to the page turning instruction based on the currently displayed page may include the following steps:

when the coprocessor receives a page turning instruction, determining whether the currently displayed page is the first page or the last page of the current chapter information;

if the currently displayed page is neither the first page of the current chapter nor the last page of the current chapter, the coprocessor determines a target page from a plurality of pages corresponding to the current chapter information according to the currently displayed page;

if the currently displayed page is the first page of the current chapter or the last page of the current chapter, the coprocessor determines the target chapter according to the currently displayed page and the chapter linked list, and determines the target page from a plurality of pages corresponding to the target chapter.

In some embodiments, the determining, by the coprocessor, a target chapter according to the currently displayed page and the chapter chain table, and determining a target page from a plurality of pages corresponding to the target chapter may include:

the coprocessor detects whether display data of a target chapter exists in the first cache space;

when the first cache space has display data of the target chapter, the coprocessor loads the display data of the target page from the first cache space to display the target page;

when the display data of the target chapter does not exist in the first cache space, the coprocessor requests the application processor for the display data of the target chapter and receives the display data of the target chapter sent by the application processor;

the coprocessor stores the display data of the target chapter into a first cache space in a page form;

and determining a target page from the pages of the target chapter of the coprocessor.

In some embodiments, the coprocessor requesting the application processor for the display data of the target chapter and receiving the display data of the target chapter sent by the application processor may include the following steps:

the coprocessor wakes up the application processor and sends a distribution request of the display data of the target chapter to the application processor;

the coprocessor deletes the display data corresponding to at least one chapter information in the first cache space;

the coprocessor receives display data of the target chapter sent by the application processor.

In step S209, the coprocessor loads the display data of the target book page from the first cache space to display the target book page.

The coprocessor loads the display data of the target page from the first cache space based on the chapter chain table so as to display the target page.

As can be seen from the above, the electronic book display method provided by this embodiment is applied to an electronic device, where the electronic device includes an application processor and a coprocessor electrically connected to the application processor, and power consumption of the coprocessor during operation is less than power consumption of the application processor during operation. The application processor scans the electronic book to extract the content of the electronic book and generates display data; the application processor sends the display data to the coprocessor, and the application processor enters a dormant state after the sending is finished; the coprocessor stores the display data into a corresponding first cache space; and the coprocessor loads the display data from the first cache space to display the page corresponding to the display data. After the application processor sends the display data of the electronic book to the coprocessor, the application processor is controlled to enter a dormant state, so that the electronic book application is run through the coprocessor with low power consumption, and the overall power consumption of the electronic equipment is reduced.

Referring to fig. 5, fig. 5 is a third flowchart illustrating a display method of an electronic book according to an embodiment of the present disclosure. The electronic device comprises an application processor and a coprocessor electrically connected with the application processor, and the power consumption of the coprocessor during operation is smaller than that of the application processor. Specifically, the method for displaying the electronic book may include the steps of:

in step S301, the application processor scans the electronic book to extract chapter information of the electronic book and text content corresponding to each chapter information, and the chapter information and the text content corresponding to each chapter information are respectively cached in the second cache space corresponding to the application processor.

In step S302, the application processor determines different text contents existing in the electronic book from all text contents in the second cache space, and converts each different text content into display data in an image form.

In step S303, the application processor acquires a first number of chapter information from the second cache space, and acquires display data corresponding to each chapter information in the first number of chapter information.

In step S304, the application processor sequentially sends the display data to the coprocessor, and the application processor enters a sleep state after the sending is completed.

In step S305, the coprocessor divides the display data corresponding to each chapter of information into a plurality of pages according to the arrangement order of the display data, the first size information of the display data in the form of an image, and the display size information of the display screen of the electronic device, and stores the display data in the form of a page in the first cache space.

In step S306, the coprocessor determines a plurality of pages corresponding to each chapter information, and sequentially adds the chapter information and the pages corresponding to each chapter information to the chapter link table in the first cache space.

In step S307, the coprocessor sequentially loads the display data corresponding to each page from the first cache space, so as to sequentially display each page of the electronic book.

Steps S301 to S307 are the same as or corresponding to steps S201 to S207, and are not described herein again.

In step S308, when the coprocessor receives the page turning instruction, the coprocessor determines a page turning mode corresponding to the page turning instruction.

When the coprocessor receives a page turning instruction of the electronic book, a page turning mode corresponding to the page turning instruction is determined. The page turning manner may include turning the page forward and turning the page backward. When the page turning mode is forward page turning, the page turning instruction is used for controlling the electronic book to turn from the currently displayed page to the target page of the previous page. When the page turning mode is backward page turning, the page turning instruction is used for controlling the electronic book to turn from the currently displayed page to a target page of a next page.

In step S309, when the page turning manner is forward page turning, the coprocessor determines whether the currently displayed page is the first page of the current chapter information.

When the page turning mode is forward page turning, the coprocessor needs to determine whether the currently displayed page is the first page in the current chapter information based on the chapter chain table. When the currently displayed page is not the first page, the operation of step S310 is performed. When the currently displayed page is the first page, the operation of step S311 is performed.

In step S310, the coprocessor takes a page preceding the currently displayed page as a target page.

The coprocessor takes a previous page of a currently displayed page as a target page based on the chapter chain table in a plurality of pages corresponding to the current chapter information in the first cache space.

In step S311, the coprocessor determines the previous chapter of the current chapter information as the target chapter, and uses the last page of the target chapter as the target page.

The coprocessor determines previous chapter information of current chapter information as a target chapter based on a chapter link table, for example, the current chapter information is the 3 rd chapter, and at this time, the coprocessor takes the previous chapter information (namely, the 2 nd chapter) as the target chapter.

In step S312, the coprocessor detects whether display data of the target chapter exists in the first cache space.

The coprocessor further detects whether the display data of the target chapter exists in the first cache space. When the display data of the target chapter information does not exist in the first cache space, it indicates that the coprocessor cannot acquire the display data corresponding to the target chapter, and at this time, the steps from S313 to S316 are sequentially executed to wake up the application processor to apply for the display data corresponding to the new target chapter from the application processor.

When the display data of the target chapter information exists in the first cache space, the display data of the target chapter is indicated to be sent to the coprocessor by the application processor, and the coprocessor carries out typesetting processing on the display data of the target chapter. Therefore, the operation of step S325 is performed.

In step S313, the coprocessor deletes the display data corresponding to the third number of chapter information stored in the first cache space according to the descending order of the chapter information.

Since the memory capacity of the first cache space of the coprocessor is limited, a part of display data needs to be deleted first before applying for the display data of a new target chapter from the application processor, so as to reserve a memory space for the display data of the new target chapter. For example, currently, the first cache space stores the display data of the 11 th chapter to the 20 th chapter, and when the user wants to page the 9 th chapter according to the page turning instruction of the user, the coprocessor may delete the display data of the third number, for example, 5 chapters according to the order of the chapter information from large to small, that is, delete the display data of the 20 th chapter to the 16 th chapter according to the order of the 20 th chapter to the 11 th chapter, and retain the display data of the 11 th chapter to the 15 th chapter. Wherein the third number is less than the first number.

In step S314, the coprocessor wakes up the application processor and sends an allocation request of the third number of chapter information to the application processor.

The coprocessor further needs to wake up the application processor and send a third number of chapter information allocation requests to the application processor.

In step S315, the application processor obtains chapter information of a third number of chapters from the target chapter according to the descending order of the chapter information, and sends the display data corresponding to each chapter information to the coprocessor.

The application processor may obtain chapter information with a third number of chapters from the target chapter according to the descending order of the chapter information. For example, when the target chapter is chapter 9, the display data of chapter 9 to chapter 5 is acquired in the order of chapter information from chapter 9, and the display data is sequentially sent to the coprocessor according to the chapter information.

In step S316, the coprocessor stores the display data in the corresponding first buffer space.

The coprocessor divides the display data corresponding to each chapter of information into a plurality of pages according to the arrangement sequence of the display data, the first size information of the display data and the second size information of the display interface, and stores the display data into corresponding first cache spaces in the form of the pages.

And the coprocessor sequentially adds pages corresponding to each chapter information to the chapter chain table of the first cache space based on the sorting order of the chapter information. At this time, the chapter link table of the first buffer space includes display data of chapters 5 to 15.

In step S317, when the page turning direction is backward page turning, the coprocessor determines whether the currently displayed page is the last page of the current chapter information.

When the page turning mode is backward page turning, the coprocessor needs to determine whether the currently displayed page is the last page in the current chapter information based on the chapter chain table. When the currently displayed page is not the last page, the operation of step S318 is performed. When the currently displayed page is the last page, step S319 is executed.

In step S318, the coprocessor takes the next page of the currently displayed page as the target page.

The coprocessor takes a next page of a currently displayed page as a target page in a plurality of pages corresponding to the current chapter information in the first cache space.

In step S319, the coprocessor determines the next chapter of the current chapter information as the target chapter, and takes the first page of the target chapter as the target page.

The coprocessor determines the next chapter information of the current chapter information as the target chapter based on the chapter link table, for example, the current chapter information is the 15 th chapter, and at this time, the coprocessor takes the next chapter information (namely, the 16 th chapter) as the target chapter.

In step S320, the coprocessor detects whether display data of the target chapter exists in the first cache space.

And the coprocessor further detects whether the display data of the target chapter exists in the first cache space. When the display data of the target chapter information does not exist in the first cache space, it indicates that the coprocessor cannot acquire the display data corresponding to the target chapter, and at this time, the operations in steps S321 to S323 are sequentially performed to wake up the application processor to apply for the display data corresponding to the new target chapter from the application processor. When the display data of the target chapter information exists in the first buffer space, step S226 is performed.

In step S321, the coprocessor deletes the display data corresponding to the third number of chapter information stored in the first cache space according to the order of the chapter information from small to large, where the third number is smaller than the first number.

Since the memory capacity of the first cache space of the coprocessor is limited, a part of display data needs to be deleted first before applying for the display data of a new target chapter from the application processor, so as to reserve a memory space for the display data of the new target chapter. For example, currently, the first cache space stores the display data of the 11 th chapter to the 20 th chapter, and when the user wants to page the 21 st chapter according to the page turning instruction of the user, the coprocessor may delete the display data of the third number, for example, 5 chapters according to the descending order of the chapter information, that is, delete the display data of the 11 th chapter to the 15 th chapter according to the order of the 11 th chapter to the 20 th chapter, and retain the display data of the 16 th chapter to the 20 th chapter. Wherein the third number is less than the first number.

In step S322, the coprocessor wakes up the application processor and sends an allocation request of a third number of target chapters to the application processor.

In step S323, the application processor acquires chapter information, the number of which is the third number, of chapters after the current chapter information according to the sequence of the chapter information from small to large, and sends display data corresponding to each chapter information to the coprocessor.

The application processor may obtain chapter information with a third number of chapters from the target chapter according to the sequence of the chapter information from small to large. For example, when the target chapter is chapter 21, the display data of chapters 21 to 25 is acquired in the order of chapter information from chapter 21 onward, and the display data is sequentially sent to the coprocessor according to the chapter information. And the application processor enters a dormant state after the display data corresponding to the chapter information with the third number of chapters is successfully sent, and the electronic book application is run through the coprocessor.

In step S324, the coprocessor stores the display data in the corresponding first buffer space.

The coprocessor divides the display data corresponding to each chapter of information into a plurality of pages according to the arrangement sequence of the display data, the first size information of the display data in the form of images and the display size information of a display screen of the electronic equipment, and stores the display data into a first cache space in the form of the pages.

In step S325, the coprocessor loads the display data corresponding to the target page from the first cache space to display the target page.

And the coprocessor loads the display data of the target book page pair application from the first cache space so as to display the target book page.

Referring to fig. 6, fig. 6 is a fourth flowchart illustrating a display method of an electronic book according to an embodiment of the present application, where the display method of the electronic book is applied to the electronic device, where the electronic device includes an application processor and a coprocessor electrically connected to the application processor, and power consumption of the coprocessor during operation is smaller than power consumption of the application processor during operation. In the method for displaying an electronic book shown in fig. 4 to 5, while the application processor extracts chapter information of the electronic book and text content corresponding to the chapter information, the application processor can also extract directory information of the electronic book and send the directory information to the coprocessor, so that the coprocessor receives the directory information sent by the application processor and displays a directory list according to target information.

Specifically, the method for displaying the electronic book may include the steps of:

in step S401, the application processor scans the electronic book to extract directory information of the electronic book, and sequentially stores each directory information in the second cache space.

The application processor scans the electronic book to extract a plurality of directory information in a directory list of the electronic book, wherein the directory information can be a chapter name corresponding to each chapter and page number information of each chapter name, and the directory information is stored in the second cache space.

In step S402, the application processor acquires a second amount of directory information and sends the second amount of directory information to the coprocessor.

Wherein the third number is greater than the first number. For example, when the directory list includes 200 directory information, the application processor may acquire the first 50 directory information, and convert each directory information into directory information in the form of an image. The bibliographic information in the form of an image is an image of 1 pixel depth (BPP). And sending the directory information in the form of 50 images to the coprocessor, controlling the application processor to enter a dormant state after the directory information is sent, and running the electronic book application through the coprocessor.

In step S403, the coprocessor sequentially stores a second amount of directory information into the corresponding first cache space.

Wherein the second number is greater than the first number. For example, when the directory list includes 200 directory information, the application processor may acquire the first 50 directory information, and convert each directory information into directory information in the form of an image. The bibliographic information in the form of an image is an image of 1 pixel depth (BPP). And sending the directory information in the form of 50 images to the coprocessor, controlling the application processor to enter a dormant state after the directory information is sent, and running the electronic book application through the coprocessor.

In step S404, the coprocessor loads a second amount of directory information from the first cache space to display the directory list of the electronic book.

When the coprocessor receives a display instruction of the directory list, the coprocessor loads each directory information from the first cache space to display the directory list of the electronic book. For example, when the coprocessor receives a display instruction of the directory list, the coprocessor sequentially displays the directory information in chapters 1 to 50 in the first cache space to generate the directory list. Of course, due to the size of the display interface of the electronic device, only the catalog information of chapters 1 to 10 may be displayed.

In some embodiments, after the step of the coprocessor loading the directory information from the first cache space to display the directory list of the electronic book, the method further includes:

the coprocessor receives sliding operation of a user and determines directory information to be displayed according to the sliding operation and a currently displayed directory list;

the coprocessor determines whether the first cache space comprises directory information to be displayed;

when the first cache space comprises directory information to be displayed, the coprocessor displays the directory information to be displayed into a directory list so as to update the directory information of the directory list;

when the first cache space does not contain the directory information to be displayed, the coprocessor wakes up the application processor, and the application processor sends the directory information to be displayed to the coprocessor;

the coprocessor stores the directory information to be displayed to the first cache space and displays the directory information to be displayed to the target list.

For example, when the first cache space includes directory information of chapters 1 to 50 and the currently displayed directory list includes directory information of chapters 41 to 50, when the user slides the directory list and wants to view the directory information of chapter 40, the directory information of chapter 11 is determined as the directory information to be displayed. Since the first cache space includes the directory information of chapter 40, the directory information of chapter 40 is directly displayed to the current directory list at this time. When a user slides a directory list and wants to view directory information of chapter 51, because the directory information of chapter 51 is not included in the first cache space, the coprocessor wakes up the application processor and requests the directory information of chapter 51 from the application processor, the application processor sends the directory information of chapter 51 to the coprocessor, and then the coprocessor loads the directory information of chapter 51 to display the directory information of chapter 51 to the directory list.

In some embodiments, the coprocessor receives a sliding operation of a user, and determines directory information to be displayed according to the sliding operation and a currently displayed directory list, including:

the coprocessor receives the sliding operation of a user and determines the sliding mode of the sliding operation;

when the sliding mode is upward sliding, the coprocessor determines the directory information to be displayed which is positioned in front of the directory information in the last column of the directory list;

when the first cache space includes directory information to be displayed, the coprocessor displays the directory information to be displayed in the directory list, so as to update the directory information of the directory list, and the step may include:

and when the first cache space comprises the directory information to be displayed, the coprocessor loads the directory information to be displayed from the first cache space and displays the directory information to be displayed so as to update the displayed directory list.

When the first cache space does not contain the directory information to be displayed, the coprocessor deletes the directory information of a preset number in the first cache space according to the sequence of the directory information from front to back;

the coprocessor wakes up the application processor and sends a distribution request of the directory information to be displayed to the application processor;

the application processor obtains a preset number of directory information from the directory information to be displayed according to the sequence of the directory information from front to back, and sends the preset number of directory information to the coprocessor;

the coprocessor stores a preset number of directory information to a first cache space;

the coprocessor loads the directory information to be displayed from the first cache space and displays the directory information to be displayed in the directory list so as to update the directory information of the directory list.

For example, when the first cache space includes the directory information of chapters 1 to 50 and the currently displayed directory list includes the directory information of chapters 41 to 50, when the sliding direction is the third direction, it indicates that the user wants to view the directory information after chapter 50, and the directory information of chapter 51 is determined as the directory information to be displayed. Since the first cache space does not include the directory information of chapter 51, the coprocessor deletes the directory information of a preset number, for example, 25, in the first cache space according to the sequence of the directory information from front to back. That is, the bibliographic information of chapters 1 to 25 is deleted, and the bibliographic information of chapters 26 to 50 is retained. Subsequently, the coprocessor wakes up the application processor, and the application processor sends the directory information of chapters 51 to 75 to the coprocessor, so that the coprocessor displays the directory information of chapters 51 to the directory list. It is understood that the updated directory listings display directory information from chapter 42 to chapter 51.

In some embodiments, when the sliding mode is sliding downwards, the coprocessor determines the directory information to be displayed before the directory information in the first column of the directory list;

When the first cache space does not contain the directory information to be displayed, the coprocessor deletes the directory information of the preset number in the first cache space according to the sequence of the directory information from back to front;

the application processor obtains a preset number of directory information from the directory information to be displayed according to the sequence of the directory information from back to front, and sends the preset number of directory information to the coprocessor;

the coprocessor loads the directory information to be displayed in the first cache space and displays the directory information to be displayed in the directory list so as to update the directory information of the directory list.

For example, when the first cache space includes directory information of chapters 11 to 60 and the currently displayed directory list includes directory information of chapters 11 to 20, when the sliding direction is the fourth direction, it indicates that the user wants to view the directory information before chapter 11, and the directory information of chapter 10 is determined as the directory information to be displayed. Since the first cache space does not include the directory information of chapter 10, the coprocessor deletes the directory information of a preset number, such as 25, in the first cache space according to the sequence of the directory information from back to front. That is, the catalog information of chapters 36 to 60 is deleted, and the catalog information of chapters 11 to 25 is retained. Subsequently, the coprocessor wakes up the application processor, and the application processor sends the directory information of chapters 1 to 10 to the coprocessor, so that the coprocessor displays the directory information of chapter 10 to the directory list. It is understood that the updated directory listings display directory information from chapters 10 through 19.

In step S405, the coprocessor receives a selection operation of the directory list, and determines selected directory information and first chapter information corresponding to the directory information according to the selection operation.

When a user selects certain directory information in the directory list, namely the coprocessor detects the selection operation of the directory list, the coprocessor determines the directory information selected by the user and the chapter information corresponding to the directory information according to the selection operation. The directory information in the directory list is provided with corresponding links, and the links of the directory information are the positions of the target pages of the chapter information corresponding to the directory information.

In step S406, the coprocessor determines whether the first buffer space includes display data of the first chapter information.

When the first cache space includes the display data of the first chapter information, step S408 is executed; when the first buffer space does not include the display data of the first chapter information, step S407 is performed.

In step S407, the coprocessor requests the application processor for display data of the first chapter information, and receives the display data of the first chapter information sent by the application processor.

The coprocessor wakes up the application processor and sends a distribution request of the display data of the first chapter information to the application processor, and the application processor sends the display data corresponding to the first chapter information to the coprocessor in sequence based on the distribution request. The coprocessor receives display data of first chapter information sent by the application processor, divides the display data corresponding to the first chapter information into a plurality of pages according to the arrangement sequence of the display data corresponding to the first chapter information, first size information in an image form and display size information of a display screen of the electronic equipment, and stores the display data into the first cache space in the page form.

In step S408, the coprocessor loads the display data of the first chapter information to display the content of the first chapter information of the electronic book.

The coprocessor loads each page of the first chapter of information in sequence to display the content of the first chapter in sequence.

Referring to fig. 7, fig. 7 is a fifth flowchart illustrating a method for displaying an electronic book according to an embodiment of the present disclosure. The electronic device comprises an application processor and a coprocessor electrically connected with the application processor, and the power consumption of the coprocessor during operation is smaller than that of the application processor. In the method for displaying an electronic book shown in fig. 4 to 5, while the application processor extracts chapter information of the electronic book and text content corresponding to the chapter information, the application processor can also extract directory information of the electronic book and send the directory information to the coprocessor, so that the coprocessor receives the directory information sent by the application processor and displays a directory list according to target information.

in step S501, the application processor scans the electronic book to extract directory information of the electronic book, and sequentially stores each directory information into a second cache space;

in step S502, the application processor acquires a second amount of directory information and sends the second amount of directory information to the coprocessor;

in step S503, the coprocessor sequentially stores a second amount of directory information into the corresponding first cache spaces.

In step S504, the coprocessor loads a second amount of directory information from the first cache space to display the directory list of the electronic book.

Steps S501 to S504 are the same as or corresponding to steps S401 to S404, and are not described herein again.

In step S505, the coprocessor receives a selection operation of the directory list, and determines selected directory information and first chapter information corresponding to the directory information according to the selection operation.

When a user selects certain directory information in the directory list, namely the coprocessor detects the selection operation of the directory list, the coprocessor determines the directory information selected by the user and the chapter information corresponding to the directory information according to the selection operation.

In step S506, the coprocessor determines a plurality of first target chapters to be loaded according to the first chapter information.

The coprocessor determines chapter information with a first number of chapters by taking chapter information corresponding to the directory information as a center; the coprocessor determines the chapter information with the chapter number being a first number as a first target chapter. For example, when the chapter information of the bibliographic information is chapter 10, a first number of chapter information such as 10 is specified centering on chapter 10, that is, chapter information of chapters 6 to 15 is specified as a first target chapter.

In step S507, the coprocessor determines whether the first buffer space includes display data of each first target chapter.

Wherein the coprocessor determines whether the first cache space includes display data for each first target chapter. For example, when the first target chapter is chapter information of chapters 6 to 15 and the display data stored in the first buffer space is display data of chapters 6 to 15, in this case, the first buffer space includes all the display data of the first target chapter (i.e., chapters 6 to 15), and the operation of step S513 is executed. When the coprocessor determines that the display data of at least one first target chapter is not included in the first cache space, step S508 is performed.

In step S508, the coprocessor deletes the display data of the chapter information in the first cache space that is not the first target chapter.

When the first cache space does not include the display data of the at least one first target chapter, the following two cases may be included: first, the first cache space includes a portion of the display data of the first target chapter. For example, if the first target chapter is chapter information from chapter 6 to chapter 15, and if the display data stored in the first buffer space is display data from chapter 1 to chapter 10, in this case, the first buffer space includes part of the display data of the first target chapter (i.e., chapter 6 to chapter 10). At this time, the coprocessor deletes the display data of the chapter information that is not the first target chapter in the first cache space, that is, deletes the display data of chapters 1 to 5.

Second, the first cache space does not include display data for any of the first target chapters. When the display data stored in the first buffer space is display data of chapters 21 to 30, in this case, the first buffer space does not include any first target chapter. At this time, the coprocessor deletes all chapter information in the first buffer space, that is, deletes the display data of chapters 1 to 10.

In step S509, the coprocessor wakes up the application processor and sends a request for allocating the display data of the first target chapter to the application processor.

The coprocessor wakes up the application processor and sends an allocation request of the display data of the first target section which does not exist in the first cache space to the application processor.

For example, if the first target chapter is chapter information from chapter 6 to chapter 15, the first buffer space includes part of the display data of the first target chapter (i.e., chapter 6 to chapter 10). In this case, the coprocessor needs to send a chapter allocation request of display data from chapter 11 to chapter 15 to the application processor.

For another example, if the first target chapter is chapter information from chapter 6 to chapter 15, the first cache space does not include any first target chapter. In this case, the coprocessor needs to send a chapter allocation request of display data from chapter 6 to chapter 15 to the application processor.

In step S510, the application processor sends the requested display data of the first target chapter to the coprocessor.

And the application processing sends the requested display data of the first target chapter to the coprocessor in sequence.

In step S511, the coprocessor stores the requested display data of the first target chapter in the corresponding first cache space.

And the coprocessor sequentially adds pages corresponding to each chapter information to the chapter chain table of the first cache space based on the sorting order of the chapter information. At this time, the chapter link table of the first buffer space includes display data of chapters 6 to 15.

In step S512, the coprocessor determines the target page from the chapter information corresponding to the catalog information.

The coprocessor determines a target page from a plurality of pages of chapter information selected by a user. The target page may be a first page of the plurality of pages of the chapter information.

In some embodiments, the coprocessor may also record the page when the user finally closes the e-book while reading each chapter, and determine that page as the target page. For example, when the user reads the electronic book in the last week, page 21 in chapter 20 has already been read, and after the user closes the electronic book, the reading situation of the user in chapter 20 is recorded. When the user selects chapter 20 from the catalog list, the user jumps directly to the position where the user read last time, i.e. page 21 in chapter 20 is directly determined as the target page.

In step S513, the coprocessor loads the display data of the target book page from the first buffer space to display the target book page.

The coprocessor loads display data corresponding to the target page from the first cache space to display the target page.

The embodiment of the application also provides a display device of the electronic book. Based on the structure of the electronic device, the display device of the electronic book provided in the embodiment of the present application is described. Referring to fig. 8, fig. 8 is a schematic structural diagram of a display device of an electronic book according to an embodiment of the present application. The display device 600 of the electronic book is applied to the electronic device, the electronic device includes an application processor and a coprocessor electrically connected to the application processor, and the power consumption of the coprocessor during operation is smaller than that of the application processor during operation.
