Abstract

The invention provides a terminal memory recovery processing method and device, and the method comprises the steps: triggering a memory recovery operation when detecting that a system idle memory is smaller than a preset threshold value; determining a memory page set through a predetermined algorithm; determining an application system to which each memory page in the memory page set belongs; determining a to-be-recovered memory page set from the memory page set according to a preset recovery ratio of each application system; and performing memory recovery processing according to the memory page set to be recovered, according to the method and the device, the problem that different influences of the same management operation on the system are not considered for the same memory recovery mechanism under multiple systems in the prior art is solved, and the effects of ensuring that all system functions are not influenced and simultaneously not influencing or reducing the user experience canbe achieved under the condition of heavy load of the system memory.

Description

Technical field [0001] The present invention relates to the field of communications, and in particular to a method and device for recycling terminal memory. Background technique [0002] Memory is a key resource of the system. When the memory is tight, there will be freezes, slower response and running speed, task running errors, and even system restarts and crashes. Therefore, memory management is one of the core technologies of the system, which plays a key role in improving the user experience of the system and the stability of system operation. Multi-system refers to running multiple application systems based on one operating system kernel. As the requirements for mobile phone security increase, multi-systems are increasingly used as an important technical solution for improving mobile phone security. However, multiple systems will greatly increase memory usage. Therefore, it is necessary to better manage memory according to the characteristics of multiple systems. Otherwis...
