[0021] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] At present, the evaluation of virtual memory page management strategy (memory swap strategy) is usually based on the following key indicators:

[0023] First, the Page Fault Rate: This is the most direct indicator. When a page fault occurs, the operating system of the electronic device must read the page from the hard disk into the memory, which is a costly operation. The lower the page fault rate, the better the performance of the memory swap strategy is usually.

[0024] Second, hit rate: This refers to the probability that the required page is already in memory when a page is referenced. The higher the hit rate, the better the performance of the memory swap strategy is generally.

[0025] Third, memory utilization: A high memory utilization rate means that the operating system of the electronic device effectively utilizes the available memory. If the memory utilization rate is low, memory resources may be wasted.

[0026] Fourth, execution time: For some specific workloads, the total execution time to complete the work can be measured to evaluate the performance of the memory swap strategy.

[0027] Fifth, fairness: In some cases, you may want to ensure that all processes have fair access to memory resources. For example, if a process often causes page faults due to its memory swap strategy, while another process can remain in memory, it may cause unfairness.

[0028] The way to evaluate these indicators is usually to run them through simulation or real system, and then measure and count the above indicators.

[0029] However, the inventors have found through research that the traditional page fault rate as an evaluation criterion may not truly reflect the system performance, especially when page faults mainly occur in I / O intensive background tasks. The hit rate may be misleading. For example, some policies may cause certain pages to reside in memory for a long time, which improves the hit rate, but in fact the usage rate of these pages is not high, which may lead to a waste of memory resources. High memory utilization is not always a good thing, especially when it leads to a higher page fault rate. In addition, excessive memory utilization may cause the system to be slow to respond to new memory requirements. Although fairness is an important indicator, it is difficult to quantify and may be interpreted differently in different environments. For example, some environments may focus more on overall performance rather than fairness.

[0030] In view of the above problems, the inventors have discovered after long-term research and proposed the memory management method, device, electronic device and storage medium provided in the embodiments of the present application. The performance evaluation of the memory exchange strategy is performed by memory recovery ratio, memory recovery error rate and / or memory recovery efficiency, which can make the evaluation results more comprehensive and accurate. Among them, the specific memory management method is described in detail in the subsequent embodiments.

[0031] See also Figure 1 , Figure 1 The flowchart of the memory management method provided by an embodiment of the present application is shown. The method is used to evaluate the performance of the memory exchange strategy by using the memory recovery ratio, memory recovery error rate and / or memory recovery efficiency, which can make the evaluation result more comprehensive and accurate. In a specific embodiment, the memory management method is applied to Fig. 9 The memory management device 200 and the electronic device 100 ( Fig.10 ). The following will take an electronic device as an example to illustrate the specific process of this embodiment. Of course, it can be understood that the electronic device used in this embodiment may include a smart phone, a tablet computer, a wearable electronic device, etc., which is not limited here. Figure 1 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0032] Step S110: When the memory of the electronic device is managed by a target memory swap strategy, determine an indicator to be evaluated that reflects the performance of the target memory swap strategy, wherein the indicator to be evaluated includes one or a combination of memory recovery ratio, memory recovery error rate, and memory recovery efficiency.

[0033] Optionally, the electronic device may pre-set and store multiple memory exchange strategies, wherein the multiple memory exchange strategies can all be used to perform memory management on the electronic device, wherein the memory exchange strategy may include Swap. As a method, the multiple memory exchange strategies each correspond to different strategies, for example, the strategy corresponding to one of the multiple memory exchange strategies is "triggering memory page replacement according to the running state of the application running on the electronic device", and the strategy corresponding to one of the multiple memory exchange strategies is "triggering memory page replacement according to the running parameters of the electronic device", etc., which are not limited here.

[0034] In this embodiment, the electronic device can select a target memory exchange strategy from multiple memory exchange strategies, and perform memory management on the electronic device through the target memory exchange strategy. Based on this, when the electronic device is managed through the target memory exchange strategy, an evaluation indicator to be used to reflect the performance of the target memory exchange strategy can be determined. Optionally, the target memory exchange strategy can be any one of the multiple memory exchange strategies.

[0035] In some embodiments, the electronic device may randomly select a memory exchange strategy from multiple memory exchange strategies as a target memory exchange strategy; the electronic device may select a memory exchange strategy from multiple memory exchange strategies in ascending order as a target memory exchange strategy; the electronic device may select a memory exchange strategy from multiple memory exchange strategies in descending order as a target memory exchange strategy; the electronic device may select a memory exchange strategy from multiple memory exchange strategies as a target memory exchange strategy according to an input selection instruction, etc., which are not limited here.

[0036] In some embodiments, the electronic device may be pre-set with an indicator to be evaluated that is used to reflect the performance of the target memory exchange policy. Therefore, when the electronic device is memory managed by the target memory exchange policy, the indicator to be evaluated that is used to reflect the performance of the target memory exchange policy may be obtained from the local of the electronic device. Optionally, in addition to being used to reflect the performance of the target memory exchange policy, the indicator to be evaluated may also be used to reflect other memory exchange policies other than the target memory exchange policy among multiple memory exchange policies, which is not limited here.

[0037] As an implementable manner, the electronic device may be pre-set with only the indicator to be evaluated, and when the memory of the electronic device is managed by the target memory exchange strategy, the indicator to be evaluated may be directly obtained from the local of the electronic device. As another implementable manner, the electronic device may be pre-set with multiple evaluation indicators including the indicator to be evaluated, and when the memory of the electronic device is managed by the target memory exchange strategy, the indicator to be evaluated may be screened out from the multiple evaluation indicators.

[0038] In some implementations, the indicator to be evaluated may include one or a combination of a memory recycling ratio, a memory recycling error rate, and a memory recycling efficiency. The memory recycling ratio may be used to evaluate the overall recycling capability of the target memory swap strategy, the memory recycling error rate may be used to evaluate the error rate of the target memory swap strategy, and the memory recycling efficiency may be used to measure the recycling efficiency of the target memory swap strategy.

[0039] Optionally, the higher the evaluation value corresponding to the memory recovery ratio under the target memory swap policy, the better the effect of the memory swap policy, and the lower the evaluation value corresponding to the memory recovery ratio under the target memory swap policy, the worse the effect of the memory swap policy; the higher the evaluation value corresponding to the memory recovery efficiency under the target memory swap policy, the better the effect of the memory swap policy, and the lower the evaluation value corresponding to the memory recovery efficiency under the target memory swap policy, the worse the effect of the memory swap policy; the higher the evaluation value corresponding to the memory recovery error rate under the target memory swap policy, the worse the effect of the memory swap policy, and the lower the evaluation value corresponding to the memory recovery error rate under the target memory swap policy, the better the effect of the memory swap policy.

[0040] Step S120: Calculate the evaluation value corresponding to the indicator to be evaluated.

[0041] In this embodiment, when the indicator to be evaluated is determined, the evaluation value corresponding to the indicator to be evaluated can be calculated.

[0042] As a method, the electronic device may be pre-set and store a target evaluation value calculation algorithm. When the indicator to be evaluated is determined, the evaluation value corresponding to the indicator to be evaluated may be calculated by the target evaluation value calculation algorithm.

[0043] As another way, the electronic device may be pre-set and store multiple evaluation value calculation algorithms. When determining the indicator to be evaluated, the target evaluation value calculation algorithm may be determined from the multiple evaluation value calculation algorithms based on the indicator to be evaluated, and the evaluation value corresponding to the indicator to be evaluated may be calculated by the target evaluation value calculation algorithm. Optionally, determining the target evaluation value calculation algorithm from the multiple evaluation value calculation algorithms based on the indicator to be evaluated may include: determining the target evaluation value calculation algorithm from the multiple evaluation value calculation algorithms based on the type of the indicator to be evaluated; determining the target evaluation value calculation algorithm from the multiple evaluation value calculation algorithms based on the number of indicators to be evaluated, etc., which is not limited here.

[0044] In some implementations, if the number of indicators to be evaluated is one (such as a memory recovery ratio), the evaluation value corresponding to the one indicator to be evaluated can be calculated, and the evaluation value corresponding to the one indicator to be evaluated can be determined as the evaluation value corresponding to the indicator to be evaluated. If the number of indicators to be evaluated is multiple (such as including a memory recovery ratio, a memory recovery error rate, and a memory recovery efficiency), the evaluation values ​​corresponding to each of the multiple indicators to be evaluated can be calculated respectively, and the evaluation value corresponding to the indicator to be evaluated can be determined based on the evaluation values ​​corresponding to each of the multiple indicators to be evaluated.

[0045] As an implementable method, determining the evaluation value corresponding to the indicator to be evaluated based on the evaluation values ​​corresponding to each of the multiple indicators to be evaluated may include: summing the evaluation values ​​corresponding to each of the multiple indicators to be evaluated to obtain the evaluation value corresponding to the indicator to be evaluated; taking a weighted sum of the evaluation values ​​corresponding to each of the multiple indicators to be evaluated to obtain the evaluation value corresponding to the indicator to be evaluated; averaging the evaluation values ​​corresponding to each of the multiple indicators to be evaluated to obtain the evaluation value corresponding to the indicator to be evaluated, etc., without limitation herein.

[0046] Step S130: Based on the evaluation value, the target memory swap policy is processed.

[0047] In this embodiment, when the evaluation value corresponding to the indicator to be evaluated is obtained, the target memory swap policy can be processed based on the evaluation value.

[0048] In some embodiments, processing the target memory swap strategy based on the evaluation value may include: based on the evaluation value, increasing the probability that the target memory swap strategy is selected; based on the evaluation value, decreasing the probability that the target memory swap strategy is selected; based on the evaluation value, increasing the score of the target memory swap strategy; based on the evaluation value, decreasing the score of the target memory swap strategy; based on the evaluation value, maintaining the use of the target memory swap strategy; based on the evaluation value, stopping the use of the target memory swap strategy, etc., without limitation herein.

[0049] A memory management method provided in an embodiment of the present application determines an indicator to be evaluated that is used to reflect the performance of a target memory exchange strategy when memory management is performed on an electronic device through a target memory exchange strategy, wherein the indicator to be evaluated includes one or a combination of memory recovery ratio, memory recovery error rate, and memory recovery efficiency, calculates an evaluation value corresponding to the indicator to be evaluated, and processes the target memory exchange strategy based on the evaluation value, thereby performing a performance evaluation of the memory exchange strategy through the memory recovery ratio, memory recovery error rate, and / or memory recovery efficiency, which can make the evaluation result more comprehensive and accurate.

[0050] See also Figure 2 , Figure 2The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 2 The process shown is described in detail, and the method may specifically include the following steps:

[0051] Step S210: When the memory of the electronic device is managed by a target memory swap strategy, determine an indicator to be evaluated that reflects the performance of the target memory swap strategy, wherein the indicator to be evaluated includes one or a combination of several of a memory recovery ratio, a memory recovery error rate, and a memory recovery efficiency.

[0052] Step S220: Calculate the evaluation value corresponding to the indicator to be evaluated.

[0053] For the detailed description of step S210 to step S220, please refer to step S110 to step S120, which will not be repeated here.

[0054] Step S230: If the evaluation value is equal to or higher than the evaluation threshold, the memory management of the electronic device is continued through the target memory swap strategy.

[0055] In some embodiments, the electronic device may be pre-set and stored with an evaluation threshold, wherein the evaluation threshold is used as a basis for judging the evaluation value corresponding to the indicator to be evaluated. Therefore, in this embodiment, when the evaluation value corresponding to the indicator to be evaluated is obtained, the evaluation value may be compared with the evaluation threshold to determine the size relationship between the evaluation value and the evaluation threshold. Optionally, the evaluation value may be lower than the evaluation threshold, may be equal to the evaluation threshold, or may be higher than the evaluation threshold. Among them, if the evaluation value is equal to or higher than the evaluation threshold, it can be determined that the indicator to be evaluated corresponding to the memory management of the electronic device through the target memory exchange strategy is higher, indicating that the effect of memory management of the electronic device through the target memory exchange strategy is better; if the evaluation value is lower than the evaluation threshold, it can be determined that the evaluation value corresponding to the memory management of the electronic device through the target memory exchange strategy is lower, indicating that the effect of memory management of the electronic device through the target memory exchange strategy is poor.

[0056] As an implementable manner, if the evaluation value is equal to or higher than the evaluation threshold, the memory management of the electronic device can be maintained through the target memory exchange strategy, so that better memory management of the electronic device can be achieved. Optionally, if the evaluation value is equal to or higher than the evaluation threshold, the probability of the target memory exchange strategy being selected can also be increased, for example, the priority of the target memory exchange strategy can be increased, the target memory exchange strategy can be marked, etc., which are not limited here.

[0057] Step S240: If the evaluation value is lower than the evaluation threshold, an alternative memory exchange strategy is selected from multiple memory exchange strategies, and memory management of the electronic device is performed using the alternative memory exchange strategy, wherein the evaluation value corresponding to the alternative memory exchange strategy is greater than the evaluation value corresponding to the target memory exchange strategy.

[0058] As an implementable method, if the evaluation value is lower than the evaluation threshold, a memory exchange strategy with a corresponding evaluation value greater than the evaluation value corresponding to the target memory exchange strategy can be selected from multiple memory exchange strategies as an alternative memory exchange strategy, and the memory of the electronic device is managed through the alternative memory exchange strategy, that is, the memory management of the electronic device is switched from the target memory exchange strategy to the alternative memory exchange strategy. Based on this, the memory management of the electronic device by replacing the memory exchange strategy with a higher evaluation value can effectively improve the memory management effect of the electronic device.

[0059] Optionally, if there is only one memory exchange policy among multiple memory exchange policies whose corresponding evaluation value is greater than the evaluation value corresponding to the target memory exchange policy, then the one memory exchange policy can be determined as the replacement memory exchange policy; if there are multiple memory exchange policies whose corresponding evaluation values ​​are greater than the evaluation value corresponding to the target memory exchange policy, then the memory exchange policy with the highest corresponding evaluation value can be determined from the multiple memory exchange policies as the replacement memory exchange policy; if there are multiple memory exchange policies whose corresponding evaluation values ​​are greater than the evaluation value corresponding to the target memory exchange policy, then the memory exchange policy with the highest priority can be determined from the multiple memory exchange policies as the replacement memory exchange policy.

[0060] Step S250: If the evaluation value is lower than the evaluation threshold, the memory exchange parameters of the target memory exchange policy are changed to obtain a changed memory exchange policy, and memory management of the electronic device is performed through the changed memory exchange policy.

[0061] As an implementable method, if the evaluation value is lower than the evaluation threshold, the memory exchange parameters of the target memory exchange strategy can be changed to obtain the changed memory exchange strategy, and the memory of the electronic device is managed by the changed memory exchange strategy. Based on this, by changing the memory exchange parameters of the memory exchange strategy, an attempt can be made to improve the memory management effect of the electronic device.

[0062] Optionally, changing the memory swap parameters of the target memory swap policy may include: changing the triggering condition of the memory swap policy; changing the memory swap size corresponding to the memory swap policy; changing the memory swap time corresponding to the memory swap policy, etc., which are not limited here.

[0063] Compared with the memory management method provided in one embodiment of the present application, Figure 1 The memory management method shown in this embodiment also maintains memory management of the electronic device through the target memory exchange strategy when the evaluation value is equal to or higher than the evaluation threshold, or, when the evaluation value is lower than the evaluation threshold, selects an alternative memory exchange strategy with a higher evaluation value from multiple memory exchange strategies, and manages the memory of the electronic device through the alternative memory exchange strategy, or, when the evaluation value is lower than the evaluation threshold, changes the memory exchange parameters of the target memory exchange strategy to obtain a changed memory exchange strategy, and manages the memory of the electronic device through the changed memory exchange strategy, so that different processing methods for the target memory exchange strategy can be determined according to different sizes of the evaluation value, which can improve the memory utilization efficiency and overall performance of the electronic device.

[0064] See also Figure 3 , Figure 3 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 3 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0065] Step S310: when the memory of the electronic device is managed by a target memory swap strategy, determining an indicator to be evaluated that reflects the performance of the target memory swap strategy, wherein the indicator to be evaluated includes a memory recovery ratio.

[0066] The specific description of step S310 can be found in step S110 , which will not be repeated here.

[0067] Step S320: Determine a first number of memory pages that are swapped from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory swap policy.

[0068] In this embodiment, the indicator to be evaluated includes a memory recovery ratio. Optionally, the memory recovery ratio can be used to evaluate the overall recovery capability of the memory swap strategy, which can be calculated by dividing the number of recovered pages by the number of all pages in the memory. In practice, the number of all pages in the memory is an instantaneous value, which can be taken as the value at the end of a round of operations.

[0069] In some embodiments, the memory exchange policy may be provided with a management period (i.e., a round of operation), wherein the management period may set the duration of application program operation, the number of times the application program is run, the number of times the application program is clicked, etc., which are not limited here. Based on this, when the memory of the electronic device is managed by the target memory exchange policy, the number of memory pages replaced from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory exchange policy may be determined as the first number.

[0070] Step S330: Determine a second number of memory pages corresponding to the remaining memory pages in the memory of the electronic device at the end of the management period indicated by the target memory swap policy.

[0071] In some embodiments, when memory management is performed on an electronic device through a target memory exchange policy, the number of memory pages remaining in the memory of the electronic device at the end of the management period indicated by the target memory exchange policy (the end of a round of operations) can be determined as the second number.

[0072] Step S340: Calculate the evaluation value corresponding to the memory recovery ratio based on the first number and the second number.

[0073] In some implementations, when the first number and the second number are obtained, the evaluation value corresponding to the memory recovery ratio can be calculated based on the first number and the second number. Optionally, the evaluation value corresponding to the memory recovery ratio can be calculated by dividing the first number by the second number.

[0074] Step S350: Based on the evaluation value, the target memory swap policy is processed.

[0075] For the detailed description of step S350, please refer to step S130, which will not be repeated here.

[0076] Compared with the memory management method provided in one embodiment of the present application, Figure 1 The memory management method shown in this embodiment also determines a first number corresponding to memory pages replaced from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory exchange policy, determines a second number corresponding to memory pages remaining in the memory of the electronic device at the end of the management period indicated by the target memory exchange policy, and calculates an evaluation value corresponding to the memory recovery ratio based on the first number and the second number, thereby improving the accuracy of the evaluation of the memory management policy.

[0077] See also Figure 4 , Figure 4 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 4The process shown is described in detail, and the memory management method may specifically include the following steps:

[0078] Step S410: when the memory of the electronic device is managed by a target memory swap strategy, determining an indicator to be evaluated that reflects the performance of the target memory swap strategy, wherein the indicator to be evaluated includes a memory recovery error rate.

[0079] For the detailed description of step S410, please refer to step S110, which will not be repeated here.

[0080] Step S420: Determine a third quantity corresponding to error pages generated by the electronic device during the management period indicated by the target memory swap policy.

[0081] In this embodiment, the indicator to be evaluated includes a memory recovery error rate. Optionally, the memory recovery error rate can be used to evaluate the error rate of the memory swap strategy, which can be calculated by dividing the cumulative error page increment by the number of all pages in the memory. In practice, the cumulative error page refers to the error page that has accumulated since the start of the test, and the number of all pages in the memory is an instantaneous value, which can be taken as the value at the end of a round of operations.

[0082] In some embodiments, the memory swap policy may be provided with a management period (i.e., a round of operation). Based on this, when the memory of the electronic device is managed by the target memory swap policy, the number of error pages generated by the electronic device during the management period indicated by the target memory swap policy may be determined as the third number.

[0083] Step S430: Determine a fourth number corresponding to the memory pages remaining in the memory of the electronic device at the end of the management period indicated by the target memory swap policy.

[0084] In some embodiments, when memory management is performed on an electronic device through a target memory exchange policy, the number of memory pages remaining in the memory of the electronic device at the end of the management period indicated by the target memory exchange policy (the end of a round of operations) can be determined as a fourth number.

[0085] Step S440: Calculate an evaluation value corresponding to the memory recovery error rate based on the third number and the fourth number.

[0086] In some implementations, when the third number and the fourth number are obtained, the evaluation value corresponding to the memory recovery error rate can be calculated based on the third number and the fourth number. Optionally, the evaluation value corresponding to the memory recovery error rate can be calculated by dividing the third number by the fourth number.

[0087] Step S450: Based on the evaluation value, the target memory swap policy is processed.

[0088] For the detailed description of step S450, please refer to step S130, which will not be repeated here.

[0089] Compared with the memory management method provided in one embodiment of the present application, Figure 1 The memory management method shown in this embodiment also determines a third number corresponding to error pages generated by the electronic device during the management period indicated by the target memory exchange policy, determines a fourth number corresponding to memory pages remaining in the memory of the electronic device at the end of the management period indicated by the target memory exchange policy, and calculates an evaluation value corresponding to the memory recovery error rate based on the third number and the fourth number, thereby improving the accuracy of the evaluation of the memory management policy.

[0090] See also Figure 5 , Figure 5 The flowchart of the memory management method provided by an embodiment of the present application is shown in FIG. Figure 5 The process shown is described in detail, and the memory management method may specifically include the following steps:

[0091] Step S510: when the memory of the electronic device is managed by a target memory swap strategy, determining an indicator to be evaluated that reflects the performance of the target memory swap strategy, wherein the indicator to be evaluated includes memory recycling efficiency.

[0092] For the detailed description of step S510, please refer to step S110, which will not be repeated here.

[0093] Step S520: Determine a fifth number corresponding to memory pages that are replaced from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory swap policy.

[0094] In this embodiment, the indicator to be evaluated includes memory recycling efficiency. Optionally, the memory recycling efficiency can be used to evaluate the memory recycling of the memory swap strategy. The higher the memory recycling efficiency, the more benefits can be obtained from replacing pages with the minimum error page cost, which can be calculated by dividing the number of recycled pages by the cumulative error page increment.

[0095] In some embodiments, the memory swap policy may be provided with a management period (i.e., a round of operation). Based on this, when the memory of the electronic device is managed by the target memory swap policy, the number of memory pages swapped from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory swap policy may be determined as the fifth number.

[0096] Step S530: Determine a sixth quantity corresponding to error pages generated by the electronic device during the management period indicated by the target memory swap policy.

[0097] In some implementations, when memory management is performed on an electronic device using a target memory swap policy, the number of error pages generated by the electronic device during a management period indicated by the target memory swap policy may be determined as a sixth number.

[0098] Step S540: Calculate the evaluation value corresponding to the memory recycling efficiency based on the fifth number and the sixth number.

[0099] In some implementations, when the fifth number and the sixth number are obtained, the evaluation value corresponding to the memory recycling efficiency can be calculated based on the fifth number and the sixth number. Optionally, the evaluation value corresponding to the memory recycling efficiency can be calculated by dividing the fifth number by the sixth number.

[0100] Step S550: Based on the evaluation value, the target memory swap policy is processed.

[0101] For the detailed description of step S550, please refer to step S130, which will not be repeated here.

[0102] Compared with the memory management method provided in one embodiment of the present application, Figure 1 The memory management method shown in this embodiment also determines a fifth number corresponding to memory pages replaced from the memory of the electronic device to the hard disk of the electronic device during the management period indicated by the target memory exchange policy, and determines a sixth number corresponding to error pages generated by the electronic device during the management period indicated by the target memory exchange policy, and calculates an evaluation value corresponding to the memory recovery efficiency based on the fifth number and the sixth number, thereby improving the accuracy of the evaluation of the memory management policy.

[0107] Step S630: obtaining an evaluation value corresponding to each memory group of the plurality of memory groups of the indicator to be evaluated.

[0108] In this embodiment, the memory of the electronic device includes multiple memory groups (such as the memcg memory group in Linux, where the LRU linked list is managed in units of memory groups, that is, the smallest unit for the memory swap policy to take effect), wherein each of the multiple memory groups may include one or more processes.

[0109] In some implementations, the multiple memory groups may be divided according to the process names included therein, may be divided according to the types of processes included therein, may be divided according to the number of processes included therein, etc., which are not limited here.

[0110] In this embodiment, the target memory exchange strategy is used to perform memory management on multiple memory groups respectively. Based on this, the indicators to be evaluated (one or a combination of memory recovery ratio, memory recovery error rate and memory recovery efficiency) can be set for the multiple memory groups respectively. When the target memory exchange strategy is used to perform memory management on the multiple memory groups respectively, the evaluation value corresponding to each memory group in the multiple memory groups can be obtained.

[0111] Step S640: Based on the evaluation value corresponding to each memory group, determine the overall evaluation value corresponding to the indicator to be evaluated.

[0112] In this embodiment, when the evaluation value corresponding to each memory group is obtained, the overall evaluation value corresponding to the indicator to be evaluated can be determined based on the evaluation value corresponding to each memory group. Optionally, when the evaluation value corresponding to each memory group is obtained, the evaluation value corresponding to each memory group can be summed to obtain the overall evaluation value corresponding to the indicator to be evaluated; or, when the evaluation value corresponding to each memory group is obtained, the evaluation value corresponding to each memory group can be weighted and summed to obtain the overall evaluation value corresponding to the indicator to be evaluated.

[0113] Step S650: Based on the overall evaluation value, the target memory swap strategy is processed.

[0123] In this embodiment, when the application program running on the electronic device and the evaluation value corresponding to the indicator to be evaluated are determined, the target memory swap strategy can be processed based on the application program and the evaluation value.

[0124] In some embodiments, when determining an application running on an electronic device, the running memory requirement of the application can be determined, and the target memory exchange strategy can be processed based on the running memory requirement and the evaluation value. For example, if the running memory requirement of the application is large, and the evaluation value corresponding to the memory exchange efficiency under the target memory exchange strategy is low, it can be switched to perform memory management on the electronic device through an alternative memory exchange strategy; if the running memory requirement of the application is low, and the evaluation value corresponding to the memory exchange efficiency under the target memory exchange strategy is low, it can continue to perform memory management on the electronic device through the target memory exchange strategy.

[0133] In this embodiment, when the operating parameters of the electronic device and the evaluation values ​​corresponding to the indicators to be evaluated are determined, the target memory swap strategy can be processed based on the operating parameters and the evaluation values.

[0134] For example, if the operating parameters indicate that the remaining power of the electronic device is insufficient, and the evaluation value corresponding to the memory exchange efficiency under the target memory exchange strategy is low, then the memory management of the electronic device can be continued through the target memory exchange strategy to extend the usage time of the electronic device; if the operating parameters indicate that the remaining power of the electronic device is sufficient, and the evaluation value corresponding to the memory exchange efficiency under the target memory exchange strategy is low, then it can be switched to memory management of the electronic device through an alternative memory exchange strategy to improve the memory management effect of the electronic device.
