Transplant of Embedded Real-time Operating System μC/OS-II

Yan Ren-hui

Abstract

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.
