摘要
嵌入式系统内存配置较小,不能采用一般桌面系统的内存管理方式,选取合适的内存管理策略在嵌入式系统设计中起着重要的作用。介绍了嵌入式系统设计中内存管理的范围、对内存分配的要求以及可能出现的问题,对内存分配的方式进行了详细的阐述,给出了内存碎片、内存丢失、执行时间不固定等问题的解决方法。
Memory is always small in embedded system because of cost, so it is very important to adopt an appropriate manner in memory management in embedded system. So the importance, its scope and possible problems of memory management in embedded real-time system are first introduced, and then memory request-and-release manner is explained in detail, and at last the solution to the problems of memory fragment, memory-losing and unfixed performing time is given.
