Embedded software memory management method

Abstract

The invention relates to the technical field of embedded software memory management, in particular to an embedded software memory management method. By means of static allocation, the partition area quantity in a system memory area and quantity and size of memory blocks in each partition area are preset, then a dynamic memory allocation mode is adopted for a user memory area on the basis of a pool-type memory management mechanism, memory application and release requests are processed through creating of a memory allocator, and traditional dynamic memory allocation and release algorithms are improved. By combination of static system memory area allocation and dynamic user area allocation, system flexibility is improved while generation of a great quantity of fragments is limited, and memoryleakage is avoided. In addition, by adoption of the method, time consumption in memory application and release can be effectively reduced, and dynamic memory management efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of embedded software memory management, in particular to an embedded software memory management method. Background technique [0002] Due to the real-time, flexibility and stability requirements of embedded systems, there are special strategies for memory management. Good program performance partly depends on its effective memory management capabilities, while the performance of conventional heap memory managers will be affected by memory fragmentation and memory recovery requirements, especially in application environments where memory is frequently allocated and released, it is more likely to become bottleneck in system performance. Not only that, but a potential memory leak could exhaust a long-running system's memory, causing a drastic drop in system performance and eventually crashing. In order to solve the problems of memory fragmentation in the heap brought about by the embedded system during memory...

Problems solved by technology

The traditional memory pool management mechanism can only allocate memory blocks of fixed size, which has poor flexibility; although other memory pool management methods can realize dynamic allocation of memory blocks, the memory space managed by the memory pool is created by defining a global array, and the array name is used as The memory pool address pointer is passed to the generation function, which is obviously not flexible enough
