Abstract

The invention discloses a memory area management method, electronic equipment and a storage medium, a memory area comprises a safe memory area and a non-safe memory area, and the method comprises thefollowing steps: obtaining a memory allocation request; when the current memory request scene is an unsafe scene, performing memory allocation on the memory allocation request by utilizing the safe memory area and the unsafe memory area; and when the current memory request scene is a safe scene, performing memory allocation on the memory allocation request by utilizing the safe memory region. By means of the mode, the use efficiency of the safe memory area can be improved, and waste of storage resources is reduced.

Description

technical field [0001] The present application relates to the technical field of computers, in particular to a method for managing memory areas, electronic equipment and storage media. Background technique [0002] At present, for the security system, in order to protect the copyright of digital media and prevent illegal copying of content, the security memory area is allocated to memory allocation requests in security scenarios, such as secure video playback. However, the secure memory area is invisible to the system, causing the system's visible memory to be lower than the actual total memory, and the system cannot allocate the secure memory area to memory allocation requests in non-secure scenarios, such as regular video playback, web browsing, and games Wait. [0003] On some platforms, the secure memory area accounts for a relatively large proportion, and on some platforms, the secure memory area can reach hundreds of megabytes. Waste of resources. Contents of the i...
