FIG. 2 is a flow diagram of a memory processing method in one embodiment. The memory processing method in this embodiment is described by taking the electronic device in fig. 1 as an example. As shown in fig. 2, the memory processing method includes steps 202 to 206.

Step 202, a memory page identifier set corresponding to a currently running application program is obtained.

The currently running application refers to an application currently in a running state, and may specifically include at least one of a foreground application and a background application. The memory page identifier set is used for storing identifiers corresponding to the memory pages. The foreground application refers to an application in an operating state of a user on the electronic device, and the background application refers to an application which is not operated by the user but runs in a background of the electronic device.

Specifically, the electronic device may obtain a currently running application program, and obtain a memory page identifier set corresponding to the currently running application program. The memory page identifier set is used to record the identifier of the memory page corresponding to the currently running application program.

In one embodiment, the memory page identification set is used to record the identification of the memory pages used by the currently running application.

In an embodiment, when the foreground application is changed, the electronic device may obtain a currently running application program, and obtain a memory page identifier set corresponding to the currently running application program.

Step 204, determining foreground application and background application in the currently running application program.

Specifically, the electronic device may determine a currently running foreground application and a currently running background application from currently running application programs, respectively.

In one embodiment, the electronic device may determine a foreground application and a background application in the currently running application program by running the task list. The electronic equipment can acquire an operating task list within a preset time length, and foreground application and background application in the currently operating application program are determined through the operating task list. That is, the electronic device may obtain a list of a group of recently-running tasks, sort the tasks according to time, rank the most recently-used application at the forefront, that is, the foreground application, and rank the other applications as background applications.

In one embodiment, the electronic device may obtain an application process information list of its own running, and determine a foreground application and a background application in the currently running application according to the application process information list. And when the process contains the background running code, judging that the application program corresponding to the process is background application. And when a certain process in the application process information list is in the display state of the front-end interface, judging that the application program corresponding to the process is foreground application.

For example, the foreground application is switched from the application a to the application B, and the application a enters the background to continue running, so that the application a and the application B are currently running applications, the application B is the foreground application, and the application a is the background application.

Step 206, obtaining foreground memory page identifiers corresponding to foreground applications in the memory page identifier set, and adjusting priorities of foreground memory pages corresponding to the foreground memory page identifiers; the priority of the adjusted foreground memory page is higher than the priority of the background memory page of the background application.

The foreground memory page identifier refers to an identifier of a memory page corresponding to a foreground application, and the foreground memory page refers to a memory page corresponding to the foreground application. The background memory page refers to a memory page corresponding to the background application.

Specifically, the priority refers to the priority of memory usage. The electronic device may obtain a foreground memory page identifier corresponding to the foreground application from the memory page identifier set. The electronic device may determine a foreground memory page corresponding to the foreground memory page identifier, and adjust the priority of the foreground memory page to increase the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page applied in the background.

In an embodiment, the electronic device may further obtain, from the memory page identifier set, a background memory page identifier corresponding to the background application. The background memory page identifier refers to an identifier of a memory page corresponding to the background application. The electronic device may determine a background memory page corresponding to the background memory page identifier, and the electronic device may adjust the priority of the foreground memory page to increase the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, a memory page identifier set corresponding to a currently running application program is obtained, foreground applications and background applications in the currently running application program are determined, and the currently running application program can be divided into the foreground applications and the background applications. The foreground memory page identifiers corresponding to the foreground applications in the memory page identifier set are acquired, the memory pages of the foreground applications and the memory pages of the background applications can be distinguished, the priority of the foreground memory page corresponding to the foreground memory page identifiers is adjusted, the priority of the foreground memory page can be improved, and the adjusted priority of the foreground memory page is higher than the priority of the background memory page of the background applications. By improving the priority of the foreground memory page, the foreground application can obtain higher memory use priority, the foreground application delay is lower, and the response speed is higher.

In one embodiment, the obtaining a foreground memory page identifier corresponding to a foreground application in the memory page identifier set, and adjusting the priority of a foreground memory page corresponding to the foreground memory page identifier includes:

A page repetitive loading error (FAE) refers to a process of loading a page to a memory for the first time, releasing a memory space of the page after the page is not accessed for a period of time, and then generating a page missing interrupt again when the page is accessed again, and needing to read related data from the external memory to the memory again. The time difference between reading the external memory and directly reading the internal memory is very large, which results in the response delay of the application. In this embodiment, by increasing the priority of the foreground application using the memory, the number of times of repeated loading errors of the page of the foreground application is reduced, so that the starting speed of the foreground application can be increased.

In one embodiment, the method further comprises: acquiring background memory page identifications corresponding to background applications in a memory page identification set, and adjusting the priority of the background memory pages corresponding to the background memory page identifications; the priority of the adjusted foreground memory page is higher than the priority of the adjusted background memory page.

Specifically, the electronic device may obtain a foreground memory page identifier corresponding to the foreground application from the memory page identifier set. The electronic device may determine a foreground memory page corresponding to the foreground memory page identifier and adjust a priority of the foreground memory page to increase the priority of the foreground memory page.

Moreover, the electronic device may further obtain a background memory page identifier corresponding to the background application from the memory page identifier set. The electronic device may determine the background memory page corresponding to the background memory page identifier, and the electronic device may adjust the priority of the background memory page to reduce the priority of the foreground memory page, so that the adjusted priority of the foreground memory page is higher than the adjusted priority of the background memory page.

In one embodiment, the electronic device may determine a foreground memory page corresponding to the foreground memory page identifier and a background memory page corresponding to the background memory page identifier, and the electronic device may obtain priorities of the foreground memory page and the background memory page and compare the priorities of the foreground memory page and the background memory page. When the priority of the foreground memory page is lower than that of the background memory page, the priority of the foreground memory page is adjusted to improve the priority of the foreground memory page, so that the priority of the foreground memory page is higher than that of the background memory page.

In one embodiment, when the priority of the foreground memory page is lower than the priority of the background memory page, the electronic device may adjust the priority of the background memory page to lower the priority of the background memory page, so that the priority of the foreground memory page is higher than the priority of the background memory page.

In this embodiment, by obtaining the background memory page identifier corresponding to the background application in the memory page identifier set, the background application can quickly and accurately find the background memory page being used by the background application through the background memory page identifier. The priority of the background memory page corresponding to the background memory page identifier is adjusted, so that the priority of the adjusted foreground memory page is higher than that of the adjusted background memory page, the priority of the foreground memory page is improved, foreground application obtains higher memory use priority, background application obtains lower memory use priority, the requirement of the background application on the memory can be reduced, and the memory response of the foreground application is promoted.

The first application identifier refers to an application identifier corresponding to a foreground application, and the second application identifier refers to an application identifier corresponding to a background application. After the electronic device determines the currently running application program, foreground application and background application in the currently running application program can be determined.

The application identifier and the memory page identifier of the same application program have a corresponding relationship. For example, the application A has a tag A, the application A has a corresponding memory page tag A-1, the application A has multiple memory pages using the same memory page tag, or different memory page tags, such as A-1, A-2, A-3, etc.

Specifically, in the case where there is an update in the application of the electronic device itself, it may be determined that there is an updated application.

and secondly, when the electronic equipment installs the application program, the electronic equipment updates the configuration file of the application program through a system framework, and the allocated application identification is recorded in the configuration file. The application identifier may be stored in a Page Table (PTE for short) and corresponds to the name of the application package. When the application program runs, the application identifier of the application program is marked in the memory page, and the application identifier is used as the memory page identifier of the memory page. In one embodiment, the electronic device uses an android operating system on which the application runs.

In one embodiment, the Kernel may obtain the application identifier corresponding to the currently running application program through a foreground perception removal mechanism.

And sixthly, the Kernel accesses the configuration file of the foreground application through a foreground perception removal mechanism and acquires the application identifier of the foreground application from the configuration file.

FIG. 5 is a diagram illustrating adjusting the priority of memory pages according to an embodiment. The electronic equipment adjusts the priority of the memory pages through the active linked list and the inactive linked list. The priority of the active linked list is higher than the priority of the inactive linked list. When the memory page identifier corresponds to the application identifier of the foreground application, it indicates that the memory page corresponding to the memory page identifier is a foreground memory page. When the memory page identifier corresponds to the application identifier of the background application, the memory page corresponding to the memory page identifier is a background memory page.

When a memory page in an active linked list or a non-active linked list is accessed, the electronic device may determine whether the accessed memory page is a foreground memory page or a background memory page.

And when the accessed memory pages are background memory pages and the background memory pages are in the active linked list, the electronic equipment moves the background memory pages to the inactive linked list. And when the accessed memory pages are background memory pages and the background memory pages are in the inactive linked list, keeping the background memory pages in the inactive linked list.

And under the condition that the accessed memory pages are foreground memory pages and the foreground memory pages are in the inactive linked list, the electronic equipment moves the foreground memory pages to the active linked list. And under the condition that the accessed memory page is a foreground memory page and the foreground memory page is in the active linked list, the electronic equipment keeps the foreground memory page in the active linked list.

And when the memory page is a clean memory page, the electronic equipment recovers the clean memory page through a recovery process. And when the memory pages are dirty memory pages, writing the dirty memory pages back to the head of the inactive linked list from the tail of the inactive linked list.

Through the memory processing of the implementation, the memory allocation and recovery priority of foreground application and background application and the probability of the memory pages of the foreground application and the background application being recovered in the system are adjusted, the demand of the background application on the memory can be reduced, the memory response of the foreground application is promoted, and the user experience of the foreground application is promoted.

the electronic device downloads the application program or updates the installed application program.

When installing an application, the electronic device configures an application identification for the installed application.

And then, the electronic equipment configures the memory page identifier corresponding to the application identifier for the updated memory page of the application program.

When the foreground application is changed, the electronic device obtains a memory page identifier set corresponding to the currently running application program.

Then, the electronic device determines a foreground application and a background application in the currently running application program, and obtains a first application identifier of the foreground application and a second application identifier of the background application.

Further, the electronic device determines, from the memory page identifier set, a foreground memory page identifier that matches the first application identifier.

Then, the electronic device determines the linked list where the foreground memory page corresponding to the foreground memory page identifier is located.

Optionally, the electronic device moves the foreground memory page to the active linked list under the condition that the foreground memory page is in the inactive linked list; under the condition that the foreground memory page is in the active linked list, the electronic equipment keeps the foreground memory page in the active linked list; the priority of the active linked list is higher than the priority of the inactive linked list.

Optionally, from the memory page identifier set, the electronic device determines a background memory page identifier matched with the second application identifier, and determines a linked list where the background memory page corresponding to the background memory page identifier is located.

And under the condition that the background memory pages are in the active linked list, the electronic equipment moves the background memory pages to the inactive linked list.

Optionally, in a case that the background memory pages are in the inactive linked list, the electronic device retains the background memory pages in the inactive linked list.

Further, the electronic device starts to recycle the memory page from the tail of the inactive linked list, and when the memory page is a clean memory page, the electronic device performs a recycling process on the clean memory page. And when the memory pages are dirty memory pages, writing the dirty memory pages back to the head of the inactive linked list from the tail of the inactive linked list.

In this embodiment, a unique application identifier is configured for each application program, and when the application program runs, a memory page identifier corresponding to the application identifier is applied to the memory page tag of the application program. When the foreground application is changed, the identification of the memory page corresponding to the currently running application program is recorded through the memory page identification set, so that the foreground memory page corresponding to the foreground application and the background memory page corresponding to the background application are accurately determined according to the corresponding relation between the application identification and the memory page identification.

The priority of the active linked list is higher than that of the inactive linked list, foreground memory pages are moved from the inactive linked list to the active linked list, and the foreground memory pages can be moved to a frequently-accessed queue. Under the condition that the foreground memory page is in the active linked list, the foreground memory page is kept in the active linked list so as to be kept in the frequently accessed queue, the priority of the foreground application for using the memory can be improved, the number of times of repeated loading errors of the foreground application page is reduced, and the starting speed of the foreground application can be accelerated.

For the background memory pages in the active linked list, the background memory pages are moved to the inactive linked list, but the background memory pages in the inactive linked list are not moved, so that the background memory pages can be all placed in the queue which is accessed infrequently, the priority of the background application for using the memory can be reduced, and the starting speed of the foreground application can be accelerated.

And the usable memory space can be increased by recycling the clean memory pages in the inactive linked list, so that the normal operation of the application program is ensured.

It should be understood that although the various steps in the flowcharts of fig. 2-3 are shown in order as indicated by the arrows, the steps are not necessarily performed in order as indicated by the arrows. The steps are not performed in the exact order shown and described, and may be performed in other orders, unless explicitly stated otherwise. Moreover, at least some of the steps in fig. 2-3 may include multiple sub-steps or multiple stages that are not necessarily performed at the same time, but may be performed at different times, and the order of performance of the sub-steps or stages is not necessarily sequential, but may be performed in turn or alternating with other steps or at least some of the sub-steps or stages of other steps.
