摘要
在嵌入式系统的开发中使用实时操作系统是当前的趋势并具有广阔的前景。针对在嵌入式微处理器上移植实时操作系统的需求,介绍嵌入式实时操作系统μC/OS-Ⅱ的内核结构和特点,MCF5307微处理器的主要特点和性能指标。分析将μC/OS-Ⅱ操作系统移植到MCF5307微处理器所需要解决的问题,重点介绍移植过程中需要修改和编写的文件和代码,同时说明移植过程中需要注意的问题。最后通过一个多任务调度的程序实例对移植结果进行了测试,说明移植工作达到了设计目的。
Using real- time operating system in the developing of embedded system is the current trend. Focus on the demand that use real - time operating system in embedded microprocessor,it introduces the structure and the character of the embedded real - time operating system μC/OS - Ⅱ , the feature and performance of MCF5307 microprocessor. Analyzing the problems faced in the transplanting ofμC/OS- Ⅱ to MCF5307 ,mainly introduces the files and the code need to be modified,and the problems should be noticed in the transplanting. The transplanting result is tested with a multitask schedule program at last, the result shows that the transplanting satisfies the demand of designing.
