Embedded system buffer internal memory distribution method

Abstract

Said method includes defining data block buffering pool data management unit structure, designing MB memory block buffer pool manager, buffer type memory allocation process and buffer memory releasing process. The present invention adopts embedded system buffer type memory allocation method, said method utilizing data block buffering pool posting distributed memory to data block buffering pool instead of immediately recovering system. Said invented method can directly use idleness data cell, until need to call system memory allocation, capable of avoid calling more operation system memory allocation and memory releasing, thereby raising system efficiency.

Description

Technical field [0001] The invention relates to the field of memory allocation strategies of an embedded system, in particular to a buffer memory allocation method of an embedded system. Background technique [0002] With the development of embedded systems, the research on the memory allocation mechanism of embedded systems is becoming more and more important. In many cases, the memory allocation mechanism is a key element that affects the efficiency of the program, so this aspect has always been the focus of research in the embedded field. Although there are many methods and related theories on the memory allocation mechanism, there are still many areas that need to be improved, and continuous research and exploration are needed. [0003] The memory allocation mechanism is an important and difficult problem in the research of embedded systems, because it must satisfy some characteristics, which are necessary for embedded systems, which is the difficulty. The following are the c...
