为提高μcos-ii 移植代码的稳定性和可靠性，避免在实际使用过程中可能出现的问题，针对 DSP TMS320F28335在进行32位数据存取时，要求偶地址对齐这一特殊情况，通过仔细分析中断过程中堆栈指针的变化，对μcos-ii的任务栈空间结构做出了相应的调整，并基于这种调整给出了移植函数及应用程序编写的指导性说明，同时设计了一个用于测试移植代码的实验。结果表明：文中所提的移植方法是可行的，能够使μcos-ii达到任务调度的目的。

In order to improve the stability and reliability of the codes for transplant μcos-ii and avoid possible problems in the using process, this paper analyzed the changes of stack pointer in the interrupt process carefully by contraposing to the fact that DSP TMS320F28335 expects memory wrappers or peripheral-interface logic to align any 32-bit read or write to an even address, made some adjustments of the task stack structure ofμcos-ii and gave a guidance of coding for transplant functions and applications based on these adjustments. At last, an experiment was designed to test the transplant codes. The result shows that this method is feasible and can achieve the task switch purpose ofμcos-ii.
