This internal memory delivery system 10 comprises and module 11, acquisition module 12, determination module 13, determination module 14 are set, find module 15 and release module 16.Module 11-16 comprises computerize programmed instruction.
Associated between priority limit under residual capacity that internal memory 30 is set and electronic installation 100 Programs 40 of module 11 is set.In electronic installation 100, each program 40 is all to there being a priority, and this priority is for the importance of sign program 40.In the present embodiment, numerical value corresponding to priority is larger, and the importance of read-me 40 is lower, and wherein, the priority of the program 40 of running background is all greater than 0, and the priority of the program 40 of front stage operation all equals 0.
In the present embodiment, described association can comprise: for example, for example, when the residual capacity of internal memory 30 is less than the first pre-set threshold value (40,000,000 (M)) and is more than or equal to the second pre-set threshold value (16M), under electronic installation 100 Programs 40, priority limit is more than or equal to the first pre-setting priority (for example 15); For example, for example, when the residual capacity of internal memory 30 is less than the second pre-set threshold value (16M) and is more than or equal to the 3rd pre-set threshold value (8M), under electronic installation 100 Programs 40, priority limit is more than or equal to the second pre-setting priority (for example 7); For example, for example, when the residual capacity of internal memory 30 is less than the 3rd pre-set threshold value (8M) and is more than or equal to the 4th pre-set threshold value (3M), under electronic installation 100 Programs 40, priority limit is more than or equal to the 3rd pre-setting priority (for example 1); For example, for example, when the residual capacity of internal memory 30 is less than the 4th pre-set threshold value (3M) and is more than or equal to the 5th pre-set threshold value (0M), under electronic installation 100 Programs 40, priority limit is greater than the 4th pre-setting priority (for example 0).
Acquisition module 12 is for the current residual capacity every a default very first time interval acquiring internal memory 30.Described very first time interval is by user or systemic presupposition, as is 50 milliseconds (ms).
When electronic installation 100 needs releasing memory 30, determination module 13, for according to the current residual capacity of internal memory 30 and described association, is determined the affiliated priority limit of theory of the program 40 that electronic installation 100 will discharge.For example, if the current residual capacity of internal memory 30 is 30M, is less than described the first pre-set threshold value and is greater than described the second pre-set threshold value, determination module 13 determines that the theoretical affiliated priority limit of program 40 that electronic installation 100 will discharge is more than or equal to 15.It should be noted that, when the residual capacity of internal memory 30 is less than described the first pre-set threshold value, and electronic installation 100 is current there is no program 40 when discharging, and illustrates that electronic installation 100 needs releasing memory 30.
Determination module 14, for whether there is the program 40 of moving according to priority limit under above-mentioned theory, is judged the actual affiliated priority limit of the current program that will discharge 40 of electronic installation 100.
