摘　　要：从不同以往的实时内核概念出发,研究了μC/OS-II内核组成结构,包括了抢占式任务调度、任务间通信等高级功能。分析了ARM7处理器的移植关键逻辑部件,并通过μC/OS-II内核对于ARM7处理器相关文件代码的移植分析和详细探讨,明晰了μC/OS-II内核在ARM7处理器移植过程中的重点和难点问题。制定了严密移植代码调试步骤并且证明了移植的正确性,移植方法对ARM应用的操作系统移植具有普遍的指导意义。The structure ofkeruel is researched including process management, scheduling, kernel synchronization, hard protection and so on, and then the ARM7 processor＇ s essential logical units concerning on transplant are analyzed, the transplant files of the μC/OS-Ⅱ kernel concerning on its debugging and porting to ARM7 processors and gives strict steps which verify porting is successful. So the method has common guidance in porting operator system to ARM and provides valuable knowledge and experience on μC/OS-Ⅱ kernel.
