一种提高μC/OS-Ⅱ操作系统安全性与稳定性的方法
A Method for Improving Security and Stability of μC/OS-Ⅱ Operating System
摘要
Abstract
This paper analyzes the security and stability of μOS-Ⅱ operating system. Using the MPU (Memory Protection Unit) of Cortex-M3 core,the memory is divided into two areas called privileged level and user level. μC/OS-Ⅱ ported to Cortex- M3 kernel is improved and optimized. It makes the operating system and user tasks run under different access levels,and uses different stack pointers to enhance the security and stability of system.关键词
