摘　　要：嵌入式系统中,内存是十分有限而且是十分珍贵的资源,而在系统运行过程中随着内存不断被分配和释放,整个系统内存区域极有可能产生越来越多的碎片,导致系统瘫痪。通过深入研究不同的内存分配策略,并分析它们的优缺点,指导不同需求下嵌入式系统内存分配策略的选择,分析LiteOS系统的存储管理模块,突显了两种内存分配策略的实际应用。In embedded systems,memory is a very limited and precious resource,and as memory is continuously allocated and released during system operation,the entire system memory area is highly likely to generate more and more fragments,leading to system paralysis.By conducting in-depth research on different memory allocation strategies and analyzing their advantages and disadvantages,guidance is given to the selection of memory allocation strategies for embedded systems on different requirements.The storage management module of LiteOS system is analyzed and highlights the practical application of two memory allocation strategies.
