摘要： 由于快速性、实时性、可靠性的要求，使得许多嵌入式应用使用自己的内存管理程序，该文概要地分析了嵌入式操作内存管理的实现原理以及它们的内存分配与回收、内存保护算法。在此基础上详细阐述面向通信领域的一种内存管理方法——UB(内存分块管理)内存管理算法，并描述了它的实现方法。

Abstract: Because of the demand of the celerity, real time and credibility , most of the application of embedded system has used themselves memory management. This paper discusses the design principal of the memory management of embedded operating system and described its arithmetic of distribute , reclaim and protection. In this base , a new measure of memory management , algorithm of UB (memory part management) memory management are described particular, and its implemention is depicted.
