摘要
研究了源码开放的嵌入式实时操作系统μC/OS Ⅱ及基于ARM7体系结构的AT91R40008微控制器,在设计的嵌入式应用平台上实现了实时操作系统μC/OS Ⅱ。整个实现工作要点可概括为:编写介于底层硬件和操作系统之间的BSP包程序;对内核中与处理器相关文件的修改;对移植好的系统进行整体测试,改善系统的实时性能。
This paper studies real time operating system μC/OS-Ⅱ with open source code and AT91R40008 based on ARM7 architecture. μC/OS-Ⅱ is implemented on the designed embedded application platform. The implementation includes: writing BSP packet acting between the hardware and the operating system; modifying the files related to processor in kernel; overall testing the transplanted system and improving the real time performance of system implemented.
