Memory allocation management method and memory allocation management system

Abstract

The invention discloses a memory allocation management method and a memory allocation management system. The method comprises the following steps: receiving the memory allocation request carried with memory size from an application program; seeking a memory block chain table with node memory size adaptive to needed memory size in a memory block chain table set aiming at the application program; in the sought memory block chain table, when the residual memory size of the node memory relative to the needed memory size is not lower than the preset lower limiting value of the node memory, allocating the memory equal to the needed memory in the node memory of one memory block to the application program, and classifying the residual memory into the target memory block chain table. According to the invention, the residual memory is classified into the target memory block chain table in which the node memory size is equal to the residual memory size, so that the memory fragments generated in the memory allocation process can be reasonably managed, and the memory utilization rate can be effectively increased.

Description

technical field [0001] The invention relates to the technical field of computer memory management, in particular to a memory allocation management method and system. Background technique [0002] As we all know, during the running process of an application program, it usually needs to allocate memory when it needs memory. Specifically, memory allocation refers to a method of allocating or reclaiming storage space during program execution. Common memory allocation methods include static memory allocation and dynamic memory allocation. The so-called dynamic memory allocation (DynamicMemoryAllocation) refers to the method of dynamically allocating or reclaiming storage space in the process of program execution. Dynamic memory allocation does not need to pre-allocate storage space like static memory allocation methods such as arrays, but is allocated by the system in real time according to the needs of the program, and the allocated size is the size required by the program. ...

Problems solved by technology

[0003] However, in practical applications, for the above two memory allocation methods, when the memory allocation management system frequently applies for and releases memory during the running of the application program, the prior art method of allocating and releasing memory through system calls is prone to memory loss. Fragmentation, which leads to low memory utilization. If it runs for a long time, it will lead to system instability, and the longer the running time, the more prone to problems the system will have, and even slower and slower
