| Abstract: | 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 poli- cies 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. |
