摘要
通过深入研究嵌入式实时内核UC/OS-Ⅱ和其在ARM7处理器上的移植范例,介绍了其调度策略及实现,描述了任务切换的完整过程,分析了UC/OS-Ⅱ的内核切换点和就绪表等关键问题,结合应用实例验证了该内核的实时性.
By studying UC/OS-Ⅱ, a real-time kernel for embedded system, and an example of its porting to an ARM7 microprocessor, this paper introduces the schedule strategy and its implementation, elaborates the whole process of context switch, analyzes the switch point and ready table of the kernel, and finally demonstrates the real-time performance with an example.
