Memory allocation method, device, storage medium and electronic equipment

Abstract

The embodiment of the present application discloses a memory allocation method, device, storage medium, and electronic equipment. In the embodiment of the present application, when a memory allocation request is received, the memory demand corresponding to the memory allocation request is determined; Whether there is a continuous free memory page matching the memory demand; when there is no continuous free memory page matching the memory demand in the memory space, determine the target memory page and the neighborhood range of the target memory page; Release the non-free memory pages within the range of the neighborhood of the target memory page to obtain continuous free memory space; respond to the memory allocation request based on the continuous free memory space, the scheme passes the free memory pages around A certain range of non-free pages is released to form continuous free memory pages, which can meet the memory application requirements and improve the efficiency of memory allocation.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a memory allocation method, device, storage medium and electronic equipment. Background technique [0002] All programs in the computer run in the memory, and the memory is also a medium for temporarily storing the calculation data in the central processing unit and exchanging data with external storage such as external disks. Therefore, the use of memory has a very large impact on computer performance. This is especially true for embedded terminals. The Android system is an operating system based on the Linux kernel for mobile terminals, and all available memory is limited to the system random access memory. [0003] As the system runs, after multiple allocation and release requests, the free page frames of the memory will become scattered, which makes it difficult to find physically continuous page frames when memory needs to be allocated. Once there are ...

[0003] As the system runs, after multiple allocation and release requests, the free page frames of the memory will become scattered, which makes it difficult to find physically continuous page frames when memory needs to be allocated

Once there are too many fragments, even if the total free memory pages meet the demand, but because the required continuous memory cannot be allocated, it will lead to a low success rate of memory allocation when allocating high-order continuous memory
