摘　　要：μC/OS-II作为一种实时性、源代码公开的嵌入式内核,已经被移植到8位、16位乃至32位单片机上。由于μC/OS-II其自身的高稳定性和实时性,并且具有可固化、可剪裁的特点,已经在许多领域都得到了应用。本文不讨论移植代码编写的具体过程,而是以凌阳单片机SPCE061A为例着重讨论了在移植μC/OS-II前需要了解的几个基本问题以及在移植μC/OS-II的过程中,OSCtxSw()和OSIntCtxSw()两个函数的比较、任务堆栈的设计以及用户中断服务子程序的编写等三个应注意的问题和以及处理它们的技巧。As a real-time ,code-open embedded kernel, μC/OS-Ⅱ has already been ported in 8-bit、16-bit and 32-bit MCU. And it has been applied to many different fields for it is real-time and has high stability and can be solidified and clipped, This paper does not discuss how the code is written, but mainly discusses several basic problems you should know before porting the μC/OS-Ⅱ and three major issues which you should pay attention to when you begin porting it. The three issues are ： differences between OSCtxSw0和OSIntCtxSw0、how to design the task stack and how to write ISR. The examples given are based on MCU SPCE061A.
