摘　　要：针对电力应用系统对嵌入式操作系统的实时性和安全性要求,以目前流行的嵌入式操作系统uC/OS-II内核为基础,巧妙地应用伙伴算法增强了内存管理模块的功能,并实现了存取控制和审计跟踪等安全功能,同时解决了内存空间的泄漏问题。经测试,本设计能很好的满足电力应用的要求。According to the time and security requirement of electric application on embedded operating system, the buddy system to enhance the capacity of memory management skillfully is applied, which is based on the uC/OS-Ⅱ. At the same time, the security policies are realized, such as, the secure access to memory and audit come true, and the problem of memory leaking is resolved. By testing, it is well adaptive in electric application.
