Detailed Description
The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
It will be appreciated that in order to enable the display of screen-to-screen data, the screen is typically signally connected directly to the processor. For example, taking an electronic device as an example, during a startup process of the electronic device or a process of switching from a screen off state to a screen on state, the processor sends a control signal to the screen through the signal connection channel, and at the same time, the screen sends a feedback signal to the processor. After receiving the feedback signal, the processor sends a data signal (screen data) to the driving circuit of the screen. Meanwhile, the driving circuit of the screen converts the received data signals into driving signals of the screen, and drives the screen to display data information, so that display is completed.
With the development of display control technology, in order to flexibly adapt to various display modes of a device, a plurality of processors are configured in a related display system to control one screen respectively. For example, as shown in fig. 1, the electronic device 100 shown in fig. 1 includes a first processor 110 and a second processor 120, and a screen 200, where the first processor 110 and the second processor 120 can control the screen 200 respectively. It should be noted that the number of processors in the embodiment of the present application may be further greater, and is not limited to only two processors in fig. 1.
In the process that the plurality of processors respectively control one screen, in order to ensure the consistency and the synchronism of the display of the screen data, when the control authority is transferred from the last processor to the next processor, the last processor can synchronously display the screen data of the current control screen to the next processor. The inventors have found in research that, as the screen size of the electronic device is larger, more data is needed to synchronize screen data. In the related screen data synchronization process, the screen data is formed by pixel values of pixels at each position of the screen, so that in the specific data synchronization process, the pixel values of the pixels at each position of the screen are synchronized from one processor to another processor at one time, and thus, the amount of data synchronized at a time is large. Taking 1920x1080 resolution of 3 bytes per pixel as an example, 6.2MB of data needs to be synchronized between the two processors, and this amount of data is sufficient to create a frame loss phenomenon when switching processors.
Therefore, the inventor proposes a screen data processing method, a device and an electronic apparatus which can improve the above problems in the present application. Therefore, in the process of switching the processors, the second processor which controls the screen synchronizes part of the screen data to the first processor before switching, and further, when the processors are actually switched, the second processor only synchronizes part of the screen data in the whole screen data, so that the first processor controls the screen to display based on the generated whole screen data, thereby reducing the data quantity of the synchronized data and the time consumed by synchronization in the switching process of the processors, and eliminating negative effects such as frame loss caused by synchronizing a large amount of screen data for a single time.
Embodiments of the present application will be described in detail below with reference to the accompanying drawings.
Referring to fig. 2, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen and a plurality of processors, each processor is configured to individually control the screen, and the method includes:
step S110: the method comprises the steps that a first processor acquires first screen data synchronized when a second processor transfers the right of controlling the screen to the first processor, wherein the first screen data are part of data in complete screen data, the first processor is a processor for controlling the screen currently, and the second processor is a previous processor for controlling the screen.
In the related screen data synchronization process, screen data synchronization is performed in units of pixels. In this way, the last processor with control authority, during the synchronization of the screen data to the next processor, transmits data describing the pixel values, for example RGB values, displayed by each pixel point. In contrast, in the embodiment of the present application, the electronic device performs modeling recognition on the content of the screen data in advance, so as to classify the content displayed on the screen, for example, may be classified into clock data, power data, date data, and the like.
Further, some attributes such as display position, size, display content, display subject, and the like may be configured for each classified data. It is understood that the display position refers to where the data of the category is displayed on the screen, and the size is the size of the data of the category, and the display content refers to the content of the data of the category to be presented to the user. For example, for clock-like screen data, the content to be presented to the user is time, for example, the current time is 12 points, and the display content is "12". For clock-like screen data, the content to be displayed to the user is the electric quantity, for example, the current electric quantity is 98%, and the display content is 98%. Further, the display theme therein characterizes at least one of a font style, a font size, an icon style, and a background picture.
Then, based on the foregoing, in the embodiment of the present application, there may be at least two implementations of the first screen data. In one mode, the first screen data is data characterizing the display content in the complete screen data. For example, the first screen data includes the aforementioned "12" characterizing the current time, and may also include "98%" characterizing the current power. In this way, the second screen data is the aforementioned attribute.
Alternatively, the first screen data is pixel data of an area in the complete screen data where the content is automatically and dynamically changed. The area in which the content is automatically and dynamically changed may be the aforementioned area in which the time is displayed, the area in which the amount of electricity is displayed, or the area in which the push information is displayed. Accordingly, in this embodiment, screen data of an area other than the area in which the content is automatically and dynamically changed is the second screen data.
It should be noted that, the complete screen data is data representing the content displayed by each pixel of the screen.
It will be appreciated that the screen of the electronic device is typically not dynamically changed except for data that dynamically changes time, power, etc. For example, in a desktop scene, icons on the desktop, descriptive text next to the icons, and the background of the entire desktop are typically static. The icons on the desktop and the descriptive text beside the icons are usually changed correspondingly after the system or the application program is updated. Similarly, the background to the desktop is changed after the user reconfigures. In this way, the electronic device may divide the display area of the screen in advance, so that each control unit in the display area may identify an area where the content is automatically and dynamically changed and an area other than the area where the content is automatically and dynamically changed, and further take the screen data corresponding to the area where the content is automatically and dynamically changed as the first screen data.
As a distinguishing method, the electronic device may establish a coordinate system with a position of a certain pixel point of the screen as an origin of coordinates, so as to divide the screen into regions by coordinates, and further, distinguish regions where contents are automatically and dynamically changed from regions other than the regions where contents are automatically and dynamically changed by coordinates.
As described above, the first processor is a processor currently configured to have the right to control the screen. Then in order to facilitate each control unit to identify whether it is already a control unit with control rights, as a way, one control unit may add data about the transfer of identification rights to the screen data during synchronization of the screen data to the other control units. Alternatively, the screen data synchronized in the embodiments of the present application may include two parts, one part being a data header and the other part being a data body. The data header may store some configuration information, such as an identification of a transmitting processor of the screen data currently synchronized, an identification of a receiving processor of the screen data currently synchronized, whether to perform rights transfer, and the like. While in the data body the screen data to be synchronized can be stored. In this way it is possible for the processor to determine, by means of the content in the data header, at the same time as the screen data, whether the currently synchronized screen data is the aforementioned first screen data or the aforementioned second screen data, and also to know whether a transfer of control rights has currently taken place, in particular to which processor.
It should be noted that, for each processor, there is a corresponding storage area for storing data. Then synchronizing screen data to another processor for one processor may be understood as one particular processor transferring screen data in its corresponding memory area to the memory area of the other processor corresponding to the stored data.
Step S120: and acquiring second screen data which are synchronized in advance by the second processor before the permission is handed over, wherein the second screen data are part of the whole screen data.
It can be appreciated that in order to reduce the data amount of screen data synchronized at the time of control authority transfer. And the processor with the control authority can synchronize part of the screen data in the part of the current screen data to the second processor after meeting the data synchronization condition, namely the processor can synchronize the second screen data to other processors after meeting the data synchronization condition. The synchronization is understood to mean that the processor currently having control authority transfers the second screen data from the storage area corresponding to itself to the storage area corresponding to the other processor. In this way, the first processor acquires the second screen data that the second processor previously synchronized before the rights are handed over, which can be understood as reading out the second screen data that the second processor previously synchronized before the rights are handed over from the storage area to which the first processor corresponds.
Step S130: complete screen data is generated based on the first screen data and the second screen data.
It should be noted that, in the embodiment, the implementation of the first screen data and the second screen data may take many forms, and then the corresponding first processor performs the process of generating the complete screen data based on the specific implementation of the first screen data and the second screen data.
Optionally, in the manner that the first screen data is data characterizing the display content in the complete screen data and the second screen data is the attribute described above, the data synchronized by the second processor in synchronizing the data to the first processor is generated based on the content object. In this manner, the first processor determines the specific content of the displayed content object from the first screen data and generates the display form of the specific content from the second screen data in the course of generating the complete screen data. For example, the first screen data received by the first processor includes a specific content of time (content object) of 12, and the second screen data received in advance includes identification data on an analog clock and identification data on a background picture of solid black, in which case the first processor generates a background picture of black and displays an analog clock on the background picture, and the analog clock displays complete screen data of time 12. For another example, the first screen data received by the first processor includes 98% of the specific content of the electric quantity (content object), and the second screen data received in advance includes identification data on the analog battery and identification data on the background picture that is solid black, in which case the first processor generates a background picture that is black and displays an analog battery on the background picture, and the analog battery displays complete screen data of 98% of the electric quantity.
The identification data is data for identifying the content object. For example, if the transmitted identification data is time_1, it may be identified as a mode clock, and for another example, if the transmitted identification data is time_2, it may be identified as a digital clock. The amount of data synchronized can be reduced by transmitting the identification data instead of directly synchronizing the pixel data of the content it identifies.
Optionally, in the manner that the first screen data is the pixel data of the area where the content is automatically and dynamically changed in the complete screen data, the screen data of the area other than the area where the content is automatically and dynamically changed is the second screen data, the data synchronized between the control units is the direct pixel data. Also, it is understood that the second processor performs in a coordinate manner in generating the first screen data and the second screen data. The first processor performs the stitching of the pixel data according to the coordinate areas corresponding to the first screen data and the second screen data in the process of generating the complete screen data, so as to generate the complete screen data. For example, as shown in FIG. 3, in the screen content shown in FIG. 3, area 99 may be used to display time, power, push information, etc., while area 98 may be used to display a desktop or display an interface for a particular application. It will be appreciated that the time, power, and push information pertains to dynamically changing content, and that the desktop or interface of a particular application may be relatively static content, the second processor may determine region 99 as being the region where the content is automatically dynamically changed, and region 98 as being a region other than the region where the content is automatically dynamically changed. It is to be understood that, when the control authority is transferred, only the pixel data of the region 99 is synchronized, and the amount of data required for the synchronization data when the control authority is switched can be reduced, compared with the case where the pixel data corresponding to the region 99 and the region 98 are synchronized in advance when the control authority is transferred.
In addition, there may be other region division methods other than the region division method shown in fig. 3. For example, as shown in fig. 4, if the area 97 is configured in the area 98 for displaying a time control, then the area 97 may also be determined as an area where the content is automatically changed dynamically, in which way the first screen data includes the pixel data of the area 99 and the area 97, and the second screen data includes the pixel data of the area 96.
Step S140: the full screen data is displayed based on controlling the screen.
In the screen data processing method, when the electronic device comprises a screen and a plurality of processors, each processor is used for independently controlling the screen, a first processor used for currently controlling the screen acquires first screen data synchronized by a previous second processor used for controlling the screen, the first screen data is partial data in complete screen data, acquires second screen data pre-synchronized by the second processor before the permission handover, the second screen data is partial data in the complete screen data, and then generates complete screen data based on the first screen data and the second screen data; and controlling the screen to display based on the generated complete screen data.
Therefore, in the process of switching the processors, the second processor which controls the screen synchronizes part of the screen data to the first processor before switching, and further, when the processors are actually switched, the second processor only synchronizes part of the screen data in the whole screen data, so that the first processor controls the screen to display based on the generated whole screen data, thereby reducing the data quantity of the synchronized data and the time consumed by synchronization in the switching process of the processors, and eliminating negative effects such as frame loss caused by synchronizing a large amount of screen data for a single time.
Referring to fig. 5, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen and a plurality of processors, each processor is configured to individually control the screen, and the method includes:
step S210: the method comprises the steps that a first processor acquires first screen data synchronized when a second processor transfers the right of controlling the screen to the first processor, wherein the first screen data are part of data in complete screen data, the first processor is a processor for controlling the screen currently, and the second processor is a previous processor for controlling the screen.
Step S220: and acquiring second screen data which are synchronized in advance by the second processor before the permission is handed over, wherein the second screen data are part of the whole screen data.
Step S230: complete screen data is generated based on the first screen data and the second screen data.
Step S240: and controlling the screen to display based on the generated complete screen data.
Step S250: and after the first processor detects that the data synchronization condition is met, synchronizing second screen data in screen data corresponding to the current display scene to the second processor, wherein the first screen data represents the display content of the current display scene, and the second screen data represents the display theme of the current display scene.
In the display theme selection scenario, the user frequently switches the display theme so as to select a display theme required by the user. Based on the foregoing, after the display theme is updated, the processor currently having the right to control the screen synchronizes the display theme selected by the user as the second screen data to the second processor, and the last synchronized second screen data will cover the last synchronized second screen data, so if the second screen data is continuously synchronized multiple times, the second screen data will not contribute to the final generation of the completed screen data, but only will be covered by the second screen data received later, which will cause great resource waste.
In order to improve the problem, as one mode, the step of synchronizing the second screen data in the screen data corresponding to the current display scene to the second processor after the first processor detects that the data synchronization condition is satisfied includes:
when the first processor detects that the data synchronization condition is met, acquiring target data, wherein the target data is part of data in second screen data in screen data corresponding to a current display scene; synchronizing the target data to the second processor and starting to detect whether a continuous transmission condition is met; and if the requirement of synchronizing the data except the target data in the second screen data in the screen data corresponding to the current display scene is met, synchronizing the data except the target data to the second processor.
Wherein, optionally, the continuous transmission condition includes: and failing to detect that the data synchronization condition is met again within a specified time period after the target data is synchronized to the second processor. It can be understood that if the satisfaction of the data synchronization condition is not detected again within the specified duration, it can be determined that the user has determined the display theme required by the user, and the switching of the display theme is not performed again within a short time. In this case the first processor may synchronize the remaining data not yet synchronized among the data requiring pre-synchronization to the second processor.
Further, optionally, the second screen data includes font style data, font size data, icon style data, and background picture data, and the target data is one of the font style data, font size data, icon style data, and background picture data, which has the smallest data amount. It will be appreciated that synchronizing the data with the smallest amount of data can further reduce wasted data transmission resources. For example, the font style data, font size data, icon style data, and background picture data included in the second screen data are sequentially 100k, 110k, 500k, and 1MB in size. The target data may in this case be determined to be font style data of 100k, since if the currently selected display theme is still switched, the wasted transmission resources, i.e. the resources consumed for transmitting this 100k, whereas if all data of 100k, 110k, 500k and 1MB are synchronized directly to the second processor, and if the currently selected display theme is still switched, more transmission resources are wasted (i.e. 1MB +500k +110k +100k = 1734KB transmission resources are wasted).
As one way, the data synchronization condition includes: after the electronic equipment is started; or when a display theme of the electronic device is changed, wherein the display theme includes at least one of a font style, a font size, an icon style, and a background picture.
It should be noted that, among the multiple processors of the electronic device provided in the embodiments of the present application, the data processing capabilities of different processors may be different. Data processing capability is understood herein as the amount of data or threads that can be processed per unit time. For example, if the first processor is a general-purpose processor and the second processor is a low-power processor, the data processing capability of the first processor is greater than that of the second processor. Then, as an adaptation manner, when the general-purpose processor is used as the first processor, the generated first screen data synchronized to the other processors (e.g., low power consumption processors) is pixel data of an area where the content is automatically dynamically changed in the complete screen data. If the general processor is used as the second processor, the generated first screen data synchronized with other processors (for example, the general processor) is the data representing the display content in the whole screen data, so that the authority of the control screen is adapted to the data processing capacity of the processor for obtaining the authority of the control screen and the data quantity required to be processed in the mutual switching process of the general processor and the low-power consumption processor, and the overall operation effect of the electronic equipment is further improved.
It will be appreciated that in the manner in which the first screen data is the data characterizing the display content in the complete screen data, the synchronized data is the indicative data identifying the display content and the display subject, and the complete screen data may be generated only after the pixel data is generated for the processor receiving the indicative data identifying the display content and the display subject, so that the data processing capability requirement for the processor generating the complete screen data based on the indicative data identifying the display content and the display subject is relatively high. In the case where the first screen data is the pixel data of the region where the content is automatically and dynamically changed in the whole screen data, the operation required for the processor that acquires the right to control the screen is simply the stitching of the pixel data, and the data processing capacity of the processor is relatively low. Therefore, the data processing capacity of the processor that obtains the authority of the control screen can be adapted to the amount of data that needs to be processed by the aforementioned configuration.
According to the screen data processing method, in the process of switching the processors, because the second processor which controls the screen synchronizes part of the screen data to the first processor before switching in advance, when the processors are actually switched, the second processor only synchronizes part of the screen data in the whole screen data, so that the first processor controls the screen to display based on the generated whole screen data, the data quantity of the synchronized data and the time consumed by synchronization in the switching process of the processors are reduced, and negative effects such as frame loss caused by single synchronization of a large amount of screen data are eliminated.
Furthermore, in the screen data processing method provided in this embodiment, the first processor synchronizes the second screen data with the second processor, so that the second screen data stored in the other processors can be updated in real time, and further, after the first processor transfers the control authority to the screen to the second processor, the second processor can also generate the screen data quickly.
Referring to fig. 6, an embodiment of the present application provides a screen data processing method applied to an electronic device, where the electronic device includes a screen and a plurality of processors, each processor is configured to individually control the screen, and the method includes:
step S310: when the electronic device enters a low power consumption mode, the second processor hands over the right to control the screen to the first processor and synchronizes the first screen data to the first processor.
It should be noted that, in this embodiment, the electronic device entering the low power consumption mode may be entering the low power consumption mode based on an event configured by automation, for example, when detecting that the electric quantity is lower than a specified value, triggering the entering the low power consumption mode, or when detecting that no application program other than a system program is running in the electronic device, triggering the entering the low power consumption mode. Furthermore, the low power consumption mode may also be entered in response to a manual operation by a user.
The low power mode may be a mode in which some functions are turned off (e.g., network access functions are turned off), or may be a sleep mode. Wherein in the sleep mode, the electronic device may only display power and time in the screen.
Step S320: the method comprises the steps that a first processor acquires first screen data synchronized when a second processor transfers the right of controlling the screen to the first processor, wherein the first screen data are part of data in complete screen data, the first processor is a processor for controlling the screen currently, and the second processor is a previous processor for controlling the screen.
Step S330: and acquiring second screen data which are synchronized in advance by the second processor before the permission is handed over, wherein the second screen data are part of the whole screen data.
Step S340: generating complete screen data based on the first screen data and the second screen data;
step S350: and controlling the screen to display based on the generated complete screen data.
According to the screen data processing method, in the process of switching the processors, because the second processor which controls the screen synchronizes part of screen data to the first processor before switching in advance, when the electronic equipment enters a low-power mode to execute actual switching of the processors, the second processor only synchronizes part of screen data in the whole screen data, so that the first processor controls the screen to display based on the generated whole screen data, and negative effects such as frame loss and the like caused by single synchronization of a large amount of screen data are eliminated.
Referring to fig. 7, a screen data processing method provided in an embodiment of the present application is applied to an electronic device, where the electronic device includes a screen, a first processor and a second processor, and the first processor and the second processor are configured to time-share control the screen display, and the method includes:
step S410: the first processor monitors screen control rights.
Step S420: and if the first processor monitors that the authority for controlling the screen is transferred from the second processor to the first processor, receiving screen content description information synchronized by the second processor, wherein the screen content description information characterizes the content to be displayed by the screen.
It will be appreciated that the screen content description information herein is description information generated based on the displayed content object, and is different from the pixel value of each specific pixel point. For example, in the example of a display clock, the content of the screen data in the form of the corresponding screen content description information may be "clock displaying a specified pattern at a specified position", and the screen data in the form of the corresponding pixel value may be the pixel value of each pixel point specified by this clock.
Step S430: the first processor controls the screen to display based on screen content description information.
