随着科技的发展,嵌入式系统的应用越来越广泛,为了进行射频功率校准系统的嵌入式软件开发,需要将嵌入式实时操作系统μC/OS-Ⅱ移植到sharp lh79520微处理器上.分析了嵌入式实时操作系统μC/OS-Ⅱ的代码结构,接着,对目前流行的嵌入式微处理器sharp lh79520的特点进行了说明,详细介绍了μC/OS-Ⅱ在sharp lh79520处理器上的移植过程,特别对OS_CPU_A.ASM文件的修改给出了详细的移植代码,最后对移植的代码进行了严格的测试,结果表明移植后的μC/OS-Ⅱ操作系统内核运行稳定可靠,验证了移植的成功.%With the development of technology, the application of embedded system is getting more and more widespread. The transplantation of the embedded real-time operating system μC/OS-Ⅱ into sharp lh79520 microprocessor is needed to develop the embedded software of RF power calibration system. The code structure of the embedded real-time operating system μC/OS- Ⅱ is analyzed. The characteristics of popular embedded microprocessor sharp lh79520 are described. The transplant process of μC/OS-Ⅱ into sharp lh79520 processor is presented. The transplant code for modifying the OS_CPU_A. ASM file is offered. The strict testing of the transplant code was conducted. The results indicate that the kernel of the transplanted μC/ OS- Ⅱ operating system runs stably and reliably.
