In one embodiment, as shown in figure 3, providing a kind of internal memory processing method, the present embodiment is applied in this way It is illustrated for electronic equipment as shown in Figure 1.This method comprises:

Step 302, the occupied recyclable memory page of application to be processed is obtained.

Application to be processed indicates the application for needing recycle committed memory.The memory (also known as deposit by arbitrary access Reservoir, random access memory, RAM) indicate the memory (i.e. running memory) used when operation program, it can only temporarily deposit Store up data, for CPU switching cache data, but memory itself cannot be used for store data long term.It is common, wait locate It ought to be with for background application.Background application is the application in running background；Accordingly, before the application in front stage operation is Platform application.The operation of one application (Application, abbreviation APP) is usually to be embodied by the operation of relevant multiple processes 's.Process (process) is program in computer about the primary operation activity on certain data acquisition system, is that system carries out resource The basic unit of distribution and scheduling, is the basis of operating system configuration.When foreground application is run the process that is related to be foreground into Journey, the process that background application is related to when running is background process.

It applies and needs committed memory space in the state of operation to store the data in operational process.Different applies The memory headroom that different operating statuses occupies is not of uniform size fixed identical.Page is that operating system internally deposits the list being managed Position, the unit memory size that the page of different electronic equipment settings occupies are not necessarily identical.Such as it is interior in electronic equipment It deposits space and is divided into 100000 pages, the page that application to be processed occupies is page 100 to page 200, and Page 130 therein to page 200 is recyclable memory page.

In one embodiment, electronic equipment can pre-recorded to be processed apply running occupied all pages, And recoverable page is obtained from all pages.Recyclable memory page table, which is shown, may be recovered, and treat place after recycling Ought to and other application operation do not impact or caused by influence lesser page.

In one embodiment, electronic equipment can record in all pages, which page is recyclable memory page, Which page is that page not can be recycled, and the recyclable memory of application occupancy to be processed is obtained according to the record information Page.

Step 304, the dependence ratio to be processed applied and relied on by foreground application is obtained.

Relying on indicates that an application needs to be used in another or the data of multiple applications and could smoothly realize to this The relationship of the execution of one application.There are two applications of dependence, the applications of the application and dependence that are respectively relied on.By In the operation of application be usually to be embodied by the operation of relevant multiple processes, the dependence between also show as process it Between dependence.For example depend on using a certain process a in A and relied on using a certain process b in B, i.e. process b by process a, Process a needs just to be able to achieve the execution to process a using the data of process b, also illustrates and depends on using A using B, or answers It is relied on B by application A, needs just to be able to achieve the execution for applying A to this using the data of application B using A, at this point, being using A The application being relied on.It is to be appreciated that the application relied on is also possible to apply for first, the second application may be background application.Electricity Sub- equipment can be detected from background application set, whether there is the background application relied on by foreground application to inquire.

Dependence ratio reflects the degree of dependence of application being relied on using being relied on by it, and degree of dependence is bigger, then according to Bad ratio is also corresponding bigger.In one embodiment, electronic equipment can record each application to the dependence ratio of other application, and It reads among the numerous dependence ratios recorded, application to be processed is by the dependence ratio of foreground application.

In one embodiment, when application to be processed is not relied on by foreground application, then relying on ratio is 0.

Step 306, application to be processed is obtained to the free time length of each recyclable memory page.

It is not applied always and is used by the data stored in page, system is indicated to the free time length of page After the application storage allocation page to be processed, the data stored in the page after the last time is by use, in not by The duration of use state.Electronic equipment carrys out each page of real-time update according to the data service condition of each page Free time length, when be ready for application to be processed occupy page recycle when, each of state-of-the-art record can be obtained The free time length of recyclable memory page.

In one embodiment, it initiates when the last time to situations such as the distribution, recycling, release of page, or to place The case where service condition cached in reason device is inquired determines to make the data for the page being accordingly related to With, and the data to page the most the last of the system time under corresponding situation will be generated and use the time, current time and The difference of the nearest time is the free time length to correspondence memory page.

In one embodiment, electronic equipment can create corresponding timestamp, timestamp record pair to each page The data in page are answered to use the time in the last.In an operating system, whenever active initiates to the distribution of memory, returns It receives, release waiting time, the liveness of correspondence memory page can be updated, and the renewal time is recorded in the timestamp. Or the service condition in timing check processor caching, can determine that the data in current cache all is currently used number According to, and the timestamp of involved page is updated, which is recorded in the timestamp.It optionally, can will most New record to renewal time replace last renewal time, to reduce the resource occupation of renewal time.

Step 308, according to the free time length of each recyclable memory page and dependence ratio-dependent duration threshold value.

Duration threshold value indicates the critical numerical value for deciding whether to recycle recyclable memory page.Duration threshold value can root The dependence ratio of application to be processed is determined, free time length according to the free time length and foreground application of each recyclable memory page Different or dependence ratio is different, and identified duration threshold value is also not necessarily identical.

In one embodiment, electronic equipment can calculate the weighted average of the free time length of all recyclable memory pages, Or can also to choose a free time length from the free time length of all recyclable memory pages, by the free time length of selection or The calculated weighted average of person, which is used as, refers to duration, and is arranged between different reference durations, dependence ratio and duration threshold value Corresponding relationship, according to the corresponding relationship obtain with this with reference to duration and the corresponding duration threshold value of dependence ratio.Such as it can be at this In the free time length for all recyclable memory pages that application to be processed occupies, choose in being close with median, or place In the free time length on a certain position that sorts, using the free time length of selection as with reference to duration.Wherein, duration threshold value and dependence Ratio and reference duration are positively correlated, bigger with reference to duration, and/or dependence ratio is bigger, then corresponding determining duration threshold value It is bigger.

Step 310, the page that free time length is more than duration threshold value is chosen from recyclable memory page to be recycled.

Electronic equipment can be according to identified duration threshold value, from the recyclable memory page that the application to be processed occupies, choosing Taking free time length is more than that the page of the duration threshold value is recycled, and to release the recyclable memory page of the duration threshold value, is supplied Foreground application or other application are used, and the integrated treatment efficiency of system is improved.Optionally, electronic equipment can by it is above-mentioned into Journey Memory recycle module 234 carries out the recycling of page according to the duration threshold value from recyclable memory page, and release long-time is not The memory used, improve memory service efficiency, and make recycle page after, influenced caused by the application to be processed also compared with It is small.In one embodiment, the storing data in the memory of recycling can store to the non-volatile memory medium of electronic equipment or It in other external storage mediums, for example can be to store the storing data in the memory of recycling to the flash memory of electronic equipment Or in the non-volatile memory medium built in hard disk etc..

For example, recyclable memory page has page 100, and corresponding free time length is respectively between 5 seconds to 15 minutes, when When determining duration threshold value is 5 minutes, the page that free time length is more than 5 minutes can be recycled from the page of page 100, The page of recycling is discharged, so that the idle page of electronic equipment accordingly increases, and can be supplied to foreground application Or other background applications are used.

Above-mentioned internal memory processing method, when by obtaining the occupied recyclable memory page of application to be processed and its free time It is long, and the dependence ratio to be processed applied and relied on by foreground application is obtained, then according to the free time length and dependence ratio come really Periodically long threshold value, and the page for being more than duration threshold value to free time length recycles, since the object of recycling is in recyclable Page is deposited, and is not necessarily that all recyclable memory pages are recycled, but according to the sky with each recyclable memory page The dependence ratio that idle length and application to be processed are relied on by foreground application, choosing free time length is more than corresponding duration threshold value Page is recycled, and further reduced the influence on system operation to application and foreground application to be processed, and the page recycled can It releases and is used for other application, guaranteed in the case where whole system memory becomes larger, most to the negative effect of each application It is small, and memory service efficiency is improved, maintain the balance between the recycling and operation to application memory to be processed.

In one embodiment, step 304 includes: whether to detect the data stored in each recyclable memory page by foreground Using dependence；The dependence ratio to be processed applied and relied on by foreground application is determined according to testing result.

Testing result includes that page is not relied on by foreground application or relied on by foreground application.Electronic equipment can for for Each recyclable memory page for being distributed of processing application, detect the data stored in correspondence memory page within a preset period of time whether It is used and arrives by foreground application, if so, determining that the page is relied on by the foreground application.Or it can be answered for the foreground With detecting it within a preset period of time, if having to use and stored in the recyclable memory page distributed by be processed apply Data, and determine that the page used is relied on by foreground application.Wherein, which can be to be at current time The period of preset duration only namely nearest period, the when a length of preset duration of the nearest period, which can It to be empirically worth any appropriate duration of setting, for example is 10 minutes or half an hour etc..Or the preset time period is also The period of front stage operation can be currently held in for foreground application.For example, foreground application 10 points 20 seconds 35 minutes to current time, It is held in front stage operation, then current slot is 10 points of 35 minute 20 seconds periods to current time.

Optionally, which can receive for the dependence sum of the recyclable memory page relied on by foreground application and client The ratio between sum of page.By detecting whether the data stored in each recyclable memory page are relied on by foreground application；In turn The dependence ratio to be processed applied and relied on by foreground application is determined according to testing result, and the standard of identified dependence ratio can be improved True property.

In one embodiment, step 310 includes: that free time length is chosen from recyclable memory page more than duration threshold value , not by foreground application rely on page recycled.

Electronic equipment can further reject the page relied on by foreground application, never be relied on by foreground application recyclable Free time length is chosen in page and is more than the page of duration threshold value, and the page of selection is recycled.By never by The page that free time length is more than duration threshold value is chosen in the page that foreground application relies on to be recycled, and can prevent from being answered by foreground It is recovered with the page of dependence and foreground application is impacted.

In one embodiment, in one embodiment, step 306 includes: to obtain the time of each recyclable memory page The renewal time of stamp record, the free time length of corresponding recyclable memory page is calculated according to renewal time.

Electronic equipment can create one by above-mentioned resource prioritization and limitation management module 222 for each page Timestamp, the timestamp indicate the time that corresponding page is used recently for recording corresponding renewal time, renewal time. When detect memory in each page by use, the renewal time that the timestamp can be recorded be updated.

Wherein, it initiates whenever the last time to situations such as the distribution, recycling, release of page, or delays in processor The case where service condition deposited is inquired determines to use the data for the page being accordingly related to, and will produce System time under raw corresponding situation is as the renewal time.It, can be according to the timestamp when starting to execute Memory recycle mechanism The renewal time of record and present system time can calculate the free time length of corresponding page.Current time is nearest with this The difference of time is the free time length to correspondence memory page.

Renewal time recording each recyclable memory page in the way of software creation time stamp, more according to this The new time determines free time length, can effectively be compatible with different processors, improve the versatility to Memory recycle.

In one embodiment, step 306 includes: to obtain by the way that the every of LRU management unit records is not used at most recently The renewal time of a recyclable memory page calculates the free time length of corresponding recyclable memory page according to renewal time.

In memory management in the processor or cache unit, setting is corresponding to be not used (Least at most recently Recently Used, LRU) administrative unit, for being counted to the memory used recently.LRU administrative unit is recordable every The renewal time of a memory address and the memory address, when the memory of a certain address is used to, processor will be corresponding Memory address and renewal time are put into LRU administrative unit and save.It, can be according to the memory when starting to execute Memory recycle mechanism Corresponding relationship between address and page would know that the corresponding page of each memory address, and then can be from LRU administrative unit The middle renewal time for reading corresponding page.Wherein, it initiates whenever the last time to feelings such as the distribution, recycling, release of page Shape, or the case where inquire the service condition cached in processor, determine the number to the page being accordingly related to According to being used, and the system time under corresponding situation will be generated as the renewal time.

After LRU administrative unit is used completely, it can produce interrupting information and notify operating system, operating system is reading LRU pipe Data therein can be emptied after managing the data of unit, so that LRU administrative unit can restart work, store each memory address And its information such as corresponding renewal time.

In the present embodiment, by creating LRU administrative unit, the service condition of each memory can be accurately tracked, is mentioned The accuracy of the high renewal time detection to page, also improves the convenience of Memory recycle.

In one embodiment, step 308 include: calculated according to the free time length of each recyclable memory page it is to be processed Using the average free duration to recyclable memory page；According to average free duration and rely on ratio-dependent duration threshold value.

Average free duration can be applied in occupied recyclable memory page to be to be processed, the occupancy duration of each page Average value.Electronic equipment can call corresponding computing unit to be counted according to the occupancy duration of each page counted on It calculates, to calculate the average free duration.Optionally, can using calculated average free duration as above-mentioned reference duration, And duration threshold value is determined with reference to duration and dependence ratio according to this.

By determining duration threshold value according to average free duration and dependence ratio, the effect of the calculating to duration threshold value can be improved Rate, and calculate simply, to also correspondingly increase the efficiency to Memory recycle.

In one embodiment, as shown in figure 4, step 308 includes:

Step 402, it obtains and the corresponding relationship to be processed using between corresponding recycling ratio and restarting duration.

After restarting duration refers to that the recyclable memory page that application to be processed occupies is recovered corresponding recycling ratio, then The duration spent when secondary starting.The corresponding relationship indicates that this, using in shared memory, recycles the recyclable memory of different proportion Afterwards, corresponding restarting duration.Optionally, which can be between corresponding recycling ratio and restarting duration The table of comparisons, or recycling proportional curve.The curve is corresponding restarting duration under different recycling ratios.According to the correspondence Relationship chooses suitable recycling ratio referring to different restarting durations, as the recyclable memory occupied to the application The recycling ratio of page.

Step 404, according to corresponding between the ratio of dependence and recyclable memory page and recycling ratio and restarting duration Relationship determines the recycling quantity of page.

The settable corresponding starting duration threshold value of electronic equipment, when restarting duration is reached the starting duration threshold value, Corresponding ratio is as the reference ratio to recyclable memory page.Starting duration threshold value can be preset empirical value, and difference is answered Can be not necessarily identical with corresponding starting duration threshold value, such as can be corresponding to determine according to the normal starting duration of corresponding application Starting duration threshold value, using 1.5 times of normal starting duration or 2 times of duration as the starting duration threshold value.It is indicated with reference to ratio Reference to page recycling ratio.According to determining reference ratio, in conjunction with the total of the ratio of dependence and recyclable memory page Number determines the recycling quantity to recyclable memory page.Recycling quantity is the recycling quantity to page, which is positive integer.

In one embodiment, pair between ratio and restarting duration is recycled in the application of different application types It should be related to also not necessarily identical.The application type is the influence on system operation of application to be processed to be arranged according to after to Memory recycle Type.Application type includes unrelated class, linear class and non-linear class.Unrelated class is indicated to the recyclable interior of application to be processed After being stored back to receipts, no matter recycle how much, to it is corresponding application and do not make significant difference.Linear class is indicated with to recyclable memory Recycling ratio increases, and the restarting duration of corresponding application is consequently increased, wherein the restarting duration and recycling ratio Relationship linear or close to linear increase between example.Non-linear class indicates other types neither unrelated class also non-linear class. Wherein, not making significant difference indicates that the corresponding restarting duration of different recycling ratios is equal beyond ratio compared to normal starting duration Less than preset proportional region.The restarting gone out close to linear expression difference recycling ratio according to the close slope fit of correspondence Duration, the error between the restarting duration under corresponding recycling ratio are no more than the error in preset range.

For example, as shown in Fig. 5 A, 5B to 5C, unrelated class, linear class and non-linear class respectively in one embodiment Application recycling proportional curve.Wherein, the abscissa in the recycling proportional curve indicates recycling ratio, and ordinate expression is in Restarting duration under corresponding recycling ratio.Wherein, the recycling proportional curve of unrelated class, which has reflected, applies and can return Page is received after being recycled in different recycling ratios, corresponding restarting duration does not change or varies less. Under different recycling ratios, corresponding slope does not change or varies less the recycling proportional curve of linear class, and non-thread Then some places slope is larger for the recycling proportional curve of property class, and some places slope is relatively small.For the application of non-linear class, The corresponding recycling ratio of minimum slope can be chosen, as the recycling ratio to recyclable memory page, i.e., as above-mentioned reference than Example.

Electronic equipment is directed to different applications, when recycling corresponding restarting after memory according to different recycling ratio It is long, affiliated application type is applied provided with this, and be arranged corresponding with the application type with reference to ratio.It is recyclable interior according to this Deposit page, dependence ratio recycling quantity corresponding with reference ratio-dependent.Further, with reference to ratio and ratio can be relied on according to this Example, determines the recycling ratio of recyclable memory page occupied to application to be processed, so can by determining recycling ratio with can return The sum for receiving page is multiplied, and the product of calculating is as recycling quantity.

When the product quantity is not integer, can choose with the approximate integer of the product, such as can according to four house five The mode entered determines that an immediate integer can be determined as recycling quantity, or also according to modes such as truncation method or transfer methods Corresponding integer is as recycling quantity.

Illustrated for determining recyclable quantity in the way of rounding up.For example, when recyclable memory page has page 100 When, if recycling ratio is 30.5%, obtained product is 30.5, then page 31 can be recycled from the recyclable memory pages of page 100, if When recycling ratio is 21.2%, then page 21 can be recycled.

By determining recycling quantity according to the restarting duration, further maintains and application memory to be processed is returned Receive the balance between operation.

Step 406, when choosing the K big free time from the free time length of each recyclable memory page according to recycling quantity It is long, using the free time length of selection as duration threshold value.

Wherein, the quantity of the free time length big more than K is recycling quantity, and K is no more than the natural number of recycling quantity.Electricity Sub- equipment can be ranked up from big to small according to the free time length of each recyclable memory page, and choose the big free time length of K, Using the free time length as duration threshold value.Wherein, the quantity of the free time length big more than K is the recycling quantity.It can manage Xie Di, K are no more than the natural number of recycling quantity.For example, the total quantity of recyclable memory page has 100, when determining returns When to receive quantity be 50, then K=51 can be from the free time length of 100 recyclable memory pages, when choosing for the 51st big free time Long, using the free time length as duration threshold value, and choosing free time length is more than in 50 recycling of the 51st big free time length Page is deposited to be recycled.

By choosing the big free time length of K as duration threshold value, improve recyclable memory is recycled it is flexible Property.

In one embodiment, step 302 includes: inquiry all pages to be processed using occupied memory；From Recyclable memory page is obtained in all pages.

Optionally, electronic equipment can record the different pages using occupied memory in real time, and be directed to each quilt The page of occupancy, further records whether it can be recovered in real time.For example, when there are the data in a certain page by Other application or application to be processed institute in use, then determine that the page is expendable page, when be recorded by Data in the page of occupancy are in nothing using state, or in the nothing When preset duration, then determine the page for recyclable memory page.
