Detailed Description
The technical solutions of the present invention will be clearly and completely described with reference to the embodiments, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
With the development of display screen technology at present, the application of color screens on wearable devices has become standard, the requirements on functions and interaction experience are higher, but more colors than monochrome data which need to be processed by a processor are limited by the main frequency, the memory space and the no-graphics hardware acceleration and cost of a main control chip, so that the display efficiency of the display system of the wearable device is lower on the basis of the existing main control chip, and the user experience is reduced. Based on the above, the embodiment of the invention provides a data display method, a data display device and electronic equipment, and the technology can be applied to applications requiring data display.
For the convenience of understanding the present embodiment, first, a data display method disclosed in the embodiment of the present invention is described in detail; the method is applied to the wearable device; the wearable device includes: the device comprises an interface processing module, a resource loading module and a content caching module; the interface processing module and the resource loading module are respectively connected with the content caching module; the content caching module comprises at least one first caching block and at least one second caching block; the cache content in the first cache block can not be deleted, and the cache content in the second cache block can be deleted; the first cache block is pre-stored with main interface data of the wearable device, and the second cache block is pre-stored with sub-interface data except the main interface data;
As shown in fig. 1, the method comprises the steps of:
Step S102, reading main interface data of the wearable device from the first cache block through an interface processing module, and displaying the main interface data through a display screen.
And step S104, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through the display screen.
Referring to a schematic structural diagram of a wearable device shown in fig. 2, the wearable device includes: the system comprises a main interface, a functional interface, a notification interface, an interface manager (corresponding to the interface processing module), a graphic library, a resource loader (corresponding to the resource loading module), an input subsystem, a content caching module and a display screen driving module (corresponding to the display screen). The input subsystem also includes a key driver and a touch screen driver. Wherein, the function interface and the notification interface belong to the sub-interfaces.
The content caching module is a caching pool, namely all available caching spaces; referring to a schematic structure of a content caching module shown in fig. 3, a cache pool is divided into a plurality of cache blocks and a cache linked list; the buffer memory block buffers different contents according to different interfaces or display contents. The cache pool is provided with a fixed cache block (corresponding to the first cache block) and a releasable cache block (corresponding to the second cache block), the cache content of the fixed cache block is undeletable, the cache content of the releasable cache block is deletable, the cache linked list is a directory of the cache blocks, and the logic sequence of the cache blocks is adjusted according to the use frequency and the current interface so as to improve the cache searching efficiency. The content to be displayed on the display screen is cached in different modes through the content caching module, so that the purposes of frame rate and experience optimization can be achieved.
The main interface is generally an interface displayed after the system is started and an interface which can be directly slid and switched in the transverse direction and the longitudinal direction, belongs to a primary interface and is also an interface which appears at the highest frequency; the method has the advantages that the method is convenient to use, the method is easy to operate, the hand-following sliding is required to be supported, the created delay, the sliding response speed and the refreshing speed are required to be the highest, therefore, for a main interface, the interface cache is selected, the whole interface is generally cached in a fixed cache block, and when the method is actually realized, the data is read from FLASH (hard disk) more slowly than from cache, and an interface manager can access a main interface cache mechanism to quickly read and display the whole screen content from a cache module when the interface is switched in a sliding manner, so that the reading time is shortened; meanwhile, the interface manager can perform main interface cache locking through the interface provided by the content cache module, so that the interface is not destroyed in the background.
The function interface is generally an interface accessed by clicking the application icon, the reminding interface is generally a notification interface, and the function interface and the notification interface are both directly jumped. Because the capacity of the buffer pool is limited, all interfaces of the device cannot be buffered, for the sub-interfaces, resource buffering is selected, and display elements used in each sub-interface are generally buffered in a releasable buffer block, so that the number of times of resource loading is reduced and the reading speed is improved.
The resource loader is a module for reading pictures and characters. When in actual implementation, the resource loader reads the sub-interface resources by calling the interface of the content caching module, and then rapidly displays the sub-interface resources through the display screen. When the resources exist in the cache, the resource loader reads the resource data from the content cache module more quickly, when the resources do not exist in the cache, the content cache module can read the resource data from FLASH (which can be understood as hardware) first, and applies for a cache block with a corresponding size from a cache pool to store the resource data, and transmits the resource data to the resource loader.
The data display method is applied to wearable equipment, and the wearable equipment comprises the following steps: the system comprises an interface processing module, a resource loading module and a content caching module, wherein the interface processing module and the resource loading module are respectively connected with the content caching module, the content caching module comprises at least one first caching block and at least one second caching block, and main interface data of the wearable device are prestored in the first caching block and cannot be deleted; sub-interface data other than the main interface data are stored in the second cache block in advance. Reading main interface data of the wearable device from the first cache block through an interface processing module, and displaying the main interface data through a display screen; the sub-interface data is read from the second cache block through the resource loading module, and is displayed through the display screen, in the mode, the main interface data is stored in the first cache block, the sub-interface data is stored in the second cache block, the display efficiency of the interface data can be improved by reading related data from the cache, and because the use frequency of the main interface data is high and the main interface data stored in the first cache block cannot be deleted, the main interface data is directly read from the first cache block, the display efficiency of the interface data of the wearable device can be further improved, and the user experience is improved.
The embodiment of the invention also provides another data display method, which is realized on the basis of the method of the embodiment; in the method, if the picture and the character exist in the sub-interface data at the same time, the mapping relation of the picture and the character in the sub-interface data is stored in the content cache module, and the picture and the character with the mapping relation are stored adjacently; the method comprises the following steps:
step one, reading main interface data of the wearable device from the first cache block through an interface processing module, and displaying the main interface data through a display screen.
Specifically, the main interface data may be stored in the first cache block through the following step a:
and a step a, when a first power-on instruction is received, loading main interface data through an interface processing module, and storing the main interface data into a first cache block.
The hardware resources of the small wearable device are limited, so that the interfaces cannot be displayed in a superimposed mode, only one interface is in a created and displayed state at any moment, and therefore, the old interfaces are destroyed and new interfaces are created when the interfaces are switched, and the picture and font resources used in the interfaces need to be initialized during creation, so that the memory storage resources need to be applied.
For the main interfaces, the number of the main interfaces can be more than 8, but the capacity of a cache pool is fixed according to the hardware selection, and the size of a cache block can be dynamically applied.
Referring to a schematic diagram of a main interface caching method shown in fig. 4, according to the selection of a cache pool, different space capacities and cache allocation strategies, each main interface can dynamically apply for a cache block with a screen size, the main interface is locked and resides in a fixed cache block, and needs to be preloaded and stored in the cache before the system is started, specifically, when the startup animation is displayed on power-on, the animation playing interval can be utilized, and the pre-caching of the main interface resources can be performed at the same time, so that after the startup animation is played, the display content of the main interface is ready, the interfaces can be guaranteed to respond to the user operation fastest, the creation process does not need to be waited, and due to the resident cache characteristic of the interfaces, the repeated destroying and creation process of the interfaces is not involved when the main interface is switched back and forth.
And step two, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through a display screen.
Specifically, the sub-interface data is stored in the second cache block through the following steps b and c:
Step b, according to the size information of the display element in the sub-interface data, acquiring a target cache area matched with the size information from the cache areas except the first cache block in the content cache module through the resource loading module, and determining the target cache area as a second cache block corresponding to the display element;
Step c, storing the display element into a corresponding second cache block; wherein the display element comprises a picture and/or a character in the sub-interface data.
The display elements, namely the resources, comprise pictures and fonts used in the sub-interfaces, and all the display elements of the sub-interfaces share all the cache spaces except for the cache space locked by the main interface in the cache pool. Referring to a schematic diagram of a sub-interface resource caching method shown in fig. 5, each resource (picture or font) in a sub-interface dynamically applies for picture cache blocks or font cache blocks with different sizes from all cache spaces except for the cache pool locked by a main interface according to the size of the resource (picture or font), and stores the picture or font into the corresponding picture cache block or font cache block.
The content caching module (corresponding to the caching pool) also comprises a caching linked list; the buffer chain table stores first identification information corresponding to the main interface in each first buffer block (corresponding to the fixed buffer block) and second identification information corresponding to the sub-interface data (corresponding to the display element of the sub-interface) in each second buffer block (corresponding to the picture buffer block or the font buffer block).
Therefore, the above-mentioned buffer chain table can be responsible for maintaining the sequence of the buffer blocks corresponding to each main interface, always keep the main interface searching path between adjacent interfaces nearest to improve efficiency, and can also maintain and replace the content of the buffer blocks to ensure that the common content of the current sub-interface can be buffered to the greatest extent to improve access speed. Meanwhile, the cache linked list can be closely related according to the pictures and fonts in the same sub-interface, namely the pictures and fonts in the same sub-interface can be automatically adjusted to the front of the cache pool, and the search hit rate of resources and fonts in the same sub-interface is improved.
In actual implementation, if the pictures and the characters exist in the display elements at the same time, when the appointed picture in the sub-interface data is loaded through the resource loading module, the appointed character with the mapping relation with the appointed picture is loaded at the same time, and the appointed character is displayed at the appointed position of the appointed picture according to the mapping relation.
Specifically, N pictures are cached in the picture caching block, M groups of fonts are cached in the font caching block, a mapping relation exists between the N pictures and the M groups of fonts, when one or more pictures in the N pictures are loaded, one or more groups of fonts in the M groups of fonts are automatically loaded according to the mapping relation, the fonts also correspond to the positions of the pictures, and when the pictures are loaded, the corresponding characters are loaded and displayed according to the mapping relation and the positional relation of the fonts.
In actual implementation, if the display element includes a character, the second buffer block corresponding to the display element also stores lattice information corresponding to the character.
In actual implementation, if the display element comprises a character, and the character is not displayed in the display screen, character information associated with the character is stored in a second cache block corresponding to the display element; wherein the character information includes: size information and coding information of the characters.
For some scenes, the characters may not need to be actually displayed in the screen, but the size information and/or the dot matrix information (graphic information of the characters) of the characters need to be used, the content caching module can determine the sliding behavior of the user in the next step according to the sliding/operating behavior of the user in the current interface, and determine whether the font caching mode is to cache the character information or the dot matrix information according to the sliding behavior of the user in the next step. Fig. 6 is a schematic diagram showing that when the text exceeds the display range, dot matrix information of the characters is not needed, that is, when the characters are not displayed on the screen, only information such as the sizes and codes of the characters are cached, and the total maximum draggable size is calculated according to the size information of the characters so as to be used for typesetting calculation. By the cache mechanism, the memory space can be saved, the high utilization rate is achieved, and the hit rate of the character lattice data cache is improved. Because the character information occupies less space, the character information can be put into an internal RAM (random access memory ) buffer memory, and the RAM is used for exchanging data with a CPU or temporarily storing data. Caching is just one use of RAM. For example, when a file is opened, the content of the file needs to be cached by using a RAM, so that the content of the file can be modified and then stored in a FLASH (hard disk). The internal RAM refers to a space available for buffering inside the main control chip, and the access speed of the RAM is far higher than that of the external RAM because the RAM is inside the chip.
Specifically, referring to a schematic diagram of a caching mechanism of character information shown in fig. 7, for the character "you", the cached size information is "wide=16, high=16"; the buffered encoded information is "code=0×1". For the character "good", the cached size information is "wide=16, high=16"; the buffered encoded information is "code=0×2". The sequence of character caching is realized by maintaining the content and the sequence of a caching linked list, the caching linked list can sequentially adjust the cached content in the next interface according to the current interface so as to improve the cache searching speed, besides, the characters have no other special caching rules, and the highest frequency of use of the characters is the forefront of the caching linked list.
The file processing method is applied to the wearable equipment, and the wearable equipment comprises the following steps: the device comprises an interface processing module, a resource loading module and a content caching module, wherein the interface processing module and the resource loading module are respectively connected with the content caching module, and the content caching module comprises at least one first caching block and at least one second caching block. When a first power-on instruction is received, loading main interface data through an interface processing module, and storing the main interface data into a first cache block, so that the interfaces can respond to user operation fastest without waiting for a creation process; acquiring a second cache block through a resource loading module, and storing display elements into the corresponding second cache block; the number of times of resource loading can be reduced, and the reading speed can be improved; the content caching module comprises a caching linked list; the cache chain table stores first identification information corresponding to the main interface data in each first cache block and second identification information corresponding to the sub-interface data in each second cache block, and the cache chain table maintains and replaces the content of the cache block to ensure that the common content of the current sub-interface can be cached to the greatest extent so as to improve the access speed. Meanwhile, the cache chain table can carry out nearby association according to the pictures and fonts in the same interface, namely the pictures and fonts in the same interface can be automatically adjusted to the front of the cache pool, so that the search hit rate of resources and fonts in the same interface is improved.
The embodiment of the invention also provides another data display method, which is realized on the basis of the method of the embodiment; as shown in fig. 8, the method includes the steps of:
step S202, reading main interface data of the wearable device from the first cache block through an interface processing module, and displaying the main interface data through a display screen.
The main interface data comprises time interface data; the first buffer memory block corresponding to the time interface data comprises: the hour hand buffer is fast, the minute hand buffer block and the second hand buffer block.
In wearable devices, the time interface often requires a display of different styles of time, such as a display with a pointer. Because of the limited hardware performance and memory space, the pointer needs to be rotated, which is extremely computationally intensive, and the time interface is typically a primary main interface, resulting in poor device interaction experience. According to the characteristics of the pointer clock, the occurrence frequency of the simultaneous change of the hour hand, the minute hand and the second hand is only one hour, most of the situations are only that the second hand is active, and aiming at the situations, an independent buffer memory space can be opened for the hour hand and the minute hand, and a buffer memory pool is resident, so that the display of three hands per second is not needed, and the calculated amount is greatly reduced.
Specifically, referring to the schematic diagram of a time interface caching method shown in fig. 9, the hour hand, the minute hand and the second hand dynamically apply for corresponding hour hand cache blocks from a cache pool according to the image sizes of the hour hand, the minute hand cache blocks and the second hand cache blocks, each rotated pointer is fixedly cached in the pointer size cache block and is not released, wherein the rotated pointer is fixedly cached in the hour hand cache block, the rotated minute hand is fixedly cached in the minute hand cache block, the rotated second hand is fixedly cached in the second hand cache block, thus each pointer does not need to rotate during each display, the sequence of each pointer cache block is maintained through a cache list, and target cache data is quickly found, so that the display of three hands is controlled.
And step S204, reading the sub-interface data from the second cache block through the resource loading module, and displaying the sub-interface data through the display screen.
Step S206, aiming at each piece of main interface data, if the data content in the main interface data is larger than the displayable area corresponding to one display screen, according to the preset division granularity, performing paging processing on the data content in the main interface data through an interface processing module to obtain a plurality of paging data corresponding to the main interface data;
In step S208, each piece of paging data is stored in the corresponding first cache block.
When the appointed content in the main interface data is required to be displayed, acquiring appointed paging data corresponding to the appointed content; specified paging data is synthesized and displayed.
In general, a text long interface will also appear in the primary main interface.
