Abstract

The invention provides a memory allocation method and device, an electronic device and a readable storage medium. A memory of the electronic device comprises a first memory area and a second memory area. The method comprises the steps of receiving a memory allocation request which comprises memory capacity needing to be allocated; comparing the memory capacity needing to be allocated with a capacity range of a preset memory block, and obtaining a comparison result; and allocating memory blocks of a corresponding capacity from a first memory area to a second memory area according to the comparison result. According to the method, by allocating the memory blocks in different memory areas, the memory blocks with different sizes are separated to be managed, memory fragmentization caused by mixed use of the memory blocks with different sizes is avoided, and thus the fragmentization occurrence probability is reduced.

Description

technical field [0001] The present invention relates to the technical field of computer storage, in particular to a memory allocation method, device, electronic equipment and a readable storage medium. Background technique [0002] At present, when receiving a memory allocation request, the electronic device directly selects a suitable area from the available memory blocks of the entire memory, without distinguishing the size of the required memory capacity. As a result, memory blocks of small capacity are continuously distributed throughout memory. After the system has been running for a period of time, the allocation and release of memory blocks continues in the system. The free physical memory of the system is divided by the used memory blocks. The large continuous physical memory blocks are 0, and the free memory blocks can only satisfy small-capacity memory blocks. distribute. That is to say, the system may still have many free memory blocks, but it cannot meet the la...
