[0001] This application belongs to the technical field of terminals, and particularly relates to a method, apparatus, and electronic device for processing pages. Background Art

[0002] Nowadays, as the functions of application programs in electronic devices such as mobile phones become more and more abundant, during the operation of application programs in electronic devices, more and more Graphics Processing Unit (GPU) memory will be occupied. To avoid memory tension in the GPU, in related technologies, usually when an application program enters the background for operation, all pages of the application program in the GPU memory will be compressed.

[0003] However, since page compression consumes the computing resources of the Central Processing Unit (CPU), it will consume a large amount of system power consumption. Summary of the Invention

[0004] The purpose of the embodiments of this application is to provide a method, apparatus, and electronic device for processing pages, which can solve the technical problem that the existing compression method consumes a large amount of system power consumption.

[0020] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0021] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such terms can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually of the same category, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means an "or" relationship between the associated objects before and after.

[0022] To solve the above technical problems, the present application provides a method for processing a page. Next, in conjunction with the accompanying drawings, the method for processing a page provided in the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0023] As Figure 1 shown, Figure 1 It is a schematic flowchart of a method for processing a page provided by an embodiment of the present application. The embodiment of the present application provides a method for processing a page, and the method may include:

[0024] S101, when the first application is running in the background of the electronic device and the electronic device does not meet the target compression condition, compress the first page of the first application in the GPU memory to obtain a first compressed page, and retain the second page of the first application in the GPU memory, where the first page is a page with a compression ratio greater than a first threshold, the second page is a page with a compression ratio less than or equal to the first threshold, and the target compression condition is a trigger condition for compressing all pages in the GPU memory;

[0025] In this embodiment, the first application is any application program in the electronic device. When the first application runs in the foreground of the electronic device, the first application will occupy GPU memory to store graphic data such as textures, frame buffers, and rendering caches to support the rendering tasks and computing tasks of its interface. When the first application switches to the background for running, the rendering tasks and some computing tasks will pause. Therefore, most of the data in the GPU memory will not be accessed in a short time, and these data can be compressed to release the GPU memory and reduce the system memory pressure.

[0026] However, the data in the GPU memory is stored and managed in the form of pages. Therefore, when the first application switches to the background of the electronic device for running, the data in the GPU memory can be compressed in units of pages.

[0027] Therefore, when the first application switches to the background of the electronic device for running, it can be further determined whether the electronic device meets the target compression condition, where the target compression condition is the trigger condition for compressing all pages in the GPU memory. If the electronic device meets the target compression condition, all pages of the first application in the GPU memory are compressed; if the electronic device does not meet the target compression condition, the first page with a high compression rate in the first application can be selected from the GPU memory for compression, while the second page with a low compression rate is retained. Retaining the second page means that for the second page with an insignificant compression effect, it is not compressed and its original page is directly retained to avoid consuming the system power during the compression process.

[0028] Among them, the compression rate refers to the proportion of the reduction in the size of the data after compression, that is:

[0029] Compression rate = 1 - size after compression / original size

[0030] For example, the original size of a page in a certain GPU memory is 16 KB, and it becomes 4 KB after compression. Then, according to the above formula, the compression rate of this page is calculated to be 75%.

[0031] Specifically, the compression rate of each page can be compared with a preset first threshold. If the compression rate is greater than the first threshold, the page is determined as the first page with a high compression rate and is compressed to obtain the first compressed page after compression. If the compression rate is less than or equal to the first threshold, the page is determined as the second page with a low compression rate and is retained. Among them, the first threshold can be set to 50% or 40%.

[0032] In addition, in some embodiments, the method further includes:

[0033] When the first application runs in the background of the electronic device and the electronic device meets the target compression condition, all pages of the first application in the GPU memory are compressed.

[0034] In this embodiment, when the first application switches to running in the background of the electronic device, it can be further determined whether the electronic device meets the target compression condition. If the electronic device meets the target compression condition, it can be considered that the GPU memory in the electronic device is relatively tight, or the compression ability of the electronic device is relatively good. Therefore, all pages of the first application in the GPU memory can be compressed to maximize the release of video memory space.

[0035] In this way, when the first application switches to running in the background and the electronic device meets the target compression condition, all pages of the first application in its GPU can be compressed, which can maximize the release of GPU memory, effectively relieve the system memory pressure, and thus improve the system fluency.

[0036] In some embodiments, the target compression condition includes any one of the following:

[0037] The available memory in the GPU is less than a third threshold;

[0038] The compression rate of the electronic device is greater than a fourth threshold.

[0039] In this embodiment, the available memory refers to the video memory that is not currently occupied by the GPU, that is, the GPU resources that can still be used for allocation. If the available memory in the GPU is less than the pre-set third threshold, it can be considered that the GPU memory is relatively tight. Therefore, the electronic device meets the target compression condition and all pages in the first application that switches to running in the background need to be compressed to maximize the release of video memory space.

[0040] The compression rate refers to the speed of processing compression tasks and decompression tasks. If the compression rate of the device is higher than the fourth threshold, it means that the system can quickly complete the compression of the data in the GPU memory, and the data compression will not significantly affect the system performance. Therefore, the electronic device meets the target compression condition, and all pages in the first application that switches to running in the background are compressed to maximize the release of video memory.

[0041] Specifically, the compression capabilities of different electronic devices are determined by the platform capabilities of their hardware platforms. Flagship platforms are equipped with GPUs and CPUs with higher computing power. Therefore, flagship platforms have stronger compression and decompression capabilities, and the time taken to compress or decompress a large amount of data is also shorter. Their compression rate is usually greater than the fourth threshold. In contrast, mid - to - low - end platforms have lower computing power, and their compression and decompression capabilities are not as good as those of flagship platforms. Their compression rate is usually less than or equal to the fourth threshold. If an electronic device on a mid - to - low - end platform compresses or decompresses a large amount of data, it takes more time and is prone to jamming. Therefore, electronic devices on flagship platforms usually meet the target compression conditions, while those on mid - to - low - end platforms do not meet the target compression conditions.

[0042] If the available memory in the GPU is greater than or equal to the third threshold, and the compression rate of the electronic device is less than or equal to the fourth threshold, then it can be considered that the available memory in the GPU is sufficient, and the compression rate of the electronic device is slow. Therefore, this electronic device does not meet the target compression conditions, and it is necessary to select the first page with a higher compression rate in the GPU memory for compression and retain the second page with a lower compression rate.

[0043] Through the above method, when the available memory in the GPU is insufficient or the compression rate of the electronic device is high, the first compression can be triggered to ensure that the GPU resources are maximally released when the memory is tight, and to avoid affecting the foreground - running applications due to insufficient video memory. At the same time, on high - performance electronic devices, the high compression rate feature can be fully utilized to maximize the release of GPU resources.

[0044] S102, clear the first page.

[0045] In the embodiments of the present application, after the compression of the first page is completed to obtain the compressed first compressed page, the system will release the original first page, freeing up space in the GPU memory, enabling the system to more efficiently utilize the GPU resources. Since the compression rate of the second page is low, the second page can be retained in the GPU memory to avoid additional CPU computing overhead during subsequent decompression.

[0046] In the present application, when the first application enters the background and the electronic device does not meet the target compression conditions, only the first page with a higher compression rate in the GPU memory is compressed to generate the first compressed page, and the original first page is cleared, while the second page with a lower compression rate remains in the GPU memory. Through the above method, only the page with a high compression rate in the GPU memory can be selected for compression, which not only releases the GPU resources but also takes into account reducing the computing power burden of the electronic device, avoiding the ineffective compression of low - compression - rate pages, and reducing the power consumption of the system while ensuring the release of memory space.

[0047] In some embodiments, the first page is a page associated with a large page identifier, and the second page is a page associated with a small page identifier. The method further includes:

[0048] Compress the third page of the first application, where the third page is a page that is not associated with the large page identifier and is not associated with the small page identifier.

[0049] In this embodiment, before compressing the pages of the first application in the GPU memory, for any page in the first application, the system will first check whether there is a large page identifier or a small page identifier associated with the page. Among them, the large page identifier is used to indicate that the page associated with it has a compression ratio less than or equal to the first threshold, and the small page identifier is used to indicate that the page associated with it has a compression ratio greater than the first threshold.

[0050] Therefore, if there is a large page identifier associated with the page, the page is determined as the second page, and the second page is retained without compressing it; if there is a small page identifier associated with the page, the page is determined as the first page, and the first page is compressed.

[0051] Among them, both the large page identifier and the small page identifier are identifiers added to the page by the system based on the comparison result of the compressed size and the original size of the page when the page is compressed for the first time.

[0052] If a certain page has neither an associated large page identifier nor an associated small page identifier, it can be considered that the page has not been compressed before. Then, the page is determined as the third page, and the third page can be compressed. During the compression process, it is determined whether the third page is the first page or the second page, and the corresponding identifier is added to it.

[0053] In this way, the pages can be classified based on the identifiers associated with the pages, and it can be determined which pages are suitable for compression, thereby avoiding ineffective compression of pages with a low compression ratio and improving the compression efficiency. At the same time, for pages that cannot be pre-classified by identifiers, compression is still performed to ensure the release of GPU resources as much as possible.

[0054] In some embodiments, the compressing the third page of the first application includes:

[0055] During the compression process of the third page, when the size of the compressed page of the third page reaches the second threshold, stop compressing the third page and associate a large page identifier with the third page.

[0056] In this embodiment, for a third page that has neither an associated large page identifier nor an associated small page identifier, it can be compressed, and during the compression process, the size of the already compressed part is continuously checked, that is, the size of the compressed page obtained by compressing the third page is checked in real time. And based on the size of the compressed page, it is dynamically determined whether to continue compressing the third page.

[0057] If during the compression of the third page, the size of the compressed page of the third page reaches the second threshold, it can be considered that the compression rate of the third page is low, and the third page already meets the standard of the second page. Then, the subsequent compression of the third page can be stopped in advance, and the third page can be directly determined as the second page with a low compression rate, and an associated large page identifier is added to it. Then, during the subsequent compression process, the third page can be directly determined as the second page, and the compression of this page can be directly skipped.

[0058] If after the compression of the third page is completed, the size of the compressed page of the third page is still smaller than the second threshold, it indicates that the compression rate of the third page is high and meets the standard of the first page. Then, an associated small page identifier can be conditionally added to it. Then, during the subsequent compression process, the third page can be directly determined as the first page, and the third page can be compressed.

[0059] Among them, since the first threshold is a pre-set compression rate standard, the product of the page size of the third page and the first threshold can be determined as the second threshold. Then, as long as the size of the compressed page of the third page reaches the second threshold, it can be determined that the compression rate of the third page is low.

[0060] For example, if the first threshold is 50%, and the page size of the third page is 16Kb, then the second threshold is 8Kb. During the compression of the third page, if it is found that the size of the compressed page has reached 8Kb when the third page is compressed to 60%, the subsequent compression of the third page can be stopped, and an associated large page identifier can be directly added to the third page.

[0061] Through the above method, the processing progress of the page can be judged in real time, the subsequent page compression can be terminated in advance when the page meets the standard of the second page, the waste of computing power can be reduced, and the overall compression efficiency can be improved. And an identifier is added to the unmarked third page during compression, which is convenient for judging the compression rate of the page during the subsequent compression process.

[0062] In some embodiments, the method further includes:

[0063] When the CPU of the electronic device is in a low-load state and the first application is running in the foreground of the electronic device, compress the fourth page of the first application in the GPU memory to obtain a fourth compressed page;

[0064] Associate the fourth compressed page with the fourth page.

[0065] In this embodiment, when the CPU of the electronic device is in a low-load state, it can be considered that there are fewer computing tasks in the current CPU and the overall utilization rate is low. For example, a state where the CPU occupancy rate is lower than 20% can be determined as the CPU being in a low-load state.

[0066] Then, when the CPU of the electronic device is in a low-load state, even if the first application is still running in the foreground of the electronic device, the fourth page that can be compressed in the first application in the GPU memory can be searched in advance, and the fourth page is compressed to obtain a fourth compressed page. After the fourth compressed page is obtained by compression, the original fourth page is still retained, and the fourth page and the fourth compressed page are associated and the fourth compressed page is stored.

[0067] For example, the compressible fourth page can be a page of static resources in the first application, and the static resources can include textures, maps of the user interface, etc.

[0068] Then, in the case where the first application is subsequently switched to the background of the electronic device, page compression of the first application is triggered. At this time, since the fourth compressed page has been pre-compressed and the compressed fourth compressed page and the fourth page are associated and stored. Therefore, the system can directly release the fourth page and use the already compressed fourth compressed page without performing additional compression calculations.

[0069] In the above-described manner, pages in the application running in the foreground can be pre-compressed when the CPU is in a low-load state, and the compressed data is associated with the original page, so that compression can be avoided when system resources are tense, and reasonable allocation of CPU computing power is achieved.

[0070] In some embodiments, after clearing the first page, the method further includes:

[0071] When the interval duration between the wake-up time of the first application running in the background and the current time is less than a first duration, decompress the first compressed page to obtain the first page, where the wake-up time is the time after the current time when the first application is switched to the foreground.

[0072] In this embodiment, after the first application is switched from running in the foreground to running in the background, in order to release the GPU memory, the first page can be compressed into a first compressed page, and then the first page is released. Subsequently, when the first application is switched back from the background to the foreground, the GPU needs to re-render the interface. At this time, the compressed first compressed page must be decompressed to restore the original resources to ensure normal display and interaction.

[0073] In this embodiment, when the first application is running in the background, the user's behavior can be predicted in real time. When it is predicted that the user will switch the first application to the foreground at the wake-up moment, and the time interval between the wake-up moment and the current moment is less than the first duration, it can be considered that the user is about to switch the first application to the foreground. Then, the pre-uncompression of GPU resources can be triggered in advance at the current moment. That is to say, even if the first application is still running in the background, the first compressed page can be automatically decompressed to obtain the first page.

[0074] In this way, when the user actually switches the first application to the foreground, there is no need to wait for decompression, and the first page can be directly used.

[0075] Through the above method, when it is predicted that the first application is about to be switched to the foreground, the GPU resources can be decompressed in advance, thereby reducing the loading delay during application switching, improving the smoothness of application switching, avoiding the user waiting for resource decompression when opening the application, and improving the system response speed.

[0078] A clearing module 202, configured to clear the first page.

[0079] In the present application, when the first application enters the background and the page processing device does not meet the target compression condition, only the first page with a higher compression ratio in the GPU memory can be compressed to generate a first compressed page, and the original first page is cleared, while the second page with a lower compression ratio remains in the GPU memory. Through the above method, only the page with a high compression ratio in the GPU memory can be selected for compression, which not only releases GPU resources but also takes into account reducing the computing power burden of the page processing device, avoids the ineffective compression of pages with a low compression ratio, and reduces the consumption of system power while ensuring the release of memory space.

Through the above method, only the page with a high compression rate in the GPU memory can be selected for compression, which not only releases GPU resources but also reduces the computing power burden of the electronic device, avoids ineffective compression of pages with a low compression rate, and reduces the consumption of system power while ensuring the release of memory space.
