Abstract

The invention provides a memory management method and an apparatus, wherein the method comprises: part of the display memory of the terminal is used as a reserve of physical memory, when the terminalis low on physical memory, moves resources that are temporarily unused in physical memory to display memory, by adopting the technical scheme, the high access speed of the display memory is fully utilized, the memory exchange rate is ensured, and the problem that the related technology cannot meet the needs of different users due to the defects of the technology for the memory resource shortage issolved.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a memory management method and device. Background technique [0002] In related technologies, with the rapid development of software technology, the demand for physical memory resources by application software is also increasing. On the one hand, it is because the volume and functions of application software are constantly increasing, resulting in the need for more memory. On the other hand, in many scenarios, it is necessary to trade space for performance, that is, to use physical memory as a cache to improve the performance of the application. This cache technology has performance bottlenecks in the hardware itself (such as insufficient CPU performance of the central processing unit, disk It is especially useful when the input and output IO performance is insufficient). [0003] It is precisely because of the continuous increase in the memory demand of software that in the u...
