An Embedded Software Memory Management Method

Abstract

The invention relates to an embedded software memory management method, and relates to the technical field of embedded software memory management. The present invention adopts the method of static allocation, presets the number of partitions in the system memory area and the number and size of memory blocks in each partition, and then adopts a dynamic memory allocation method for the user memory area based on the pool memory management mechanism. The memory allocator handles memory application and release requests, and improves the traditional dynamic memory allocation and release algorithms. This method uses a combination of static allocation of system memory area and dynamic allocation of user memory area, which increases the flexibility of the system, and at the same time limits the generation of a large number of fragments, avoiding the occurrence of memory leaks, and this method can effectively reduce the application and It takes time to release memory and improve the efficiency of dynamic memory management.

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
