摘要
分析μC/OS-Ⅱ的任务调度算法,指出其优势和需要改进之处。在此基础上,对μC/OS-Ⅱ的任务调度算法进行了扩展,使之可以支持优先级共享和分时调度,并给出了实现任务管理的核心算法的设计。实践证明,对μC/OS-Ⅱ的任务调度算法的扩展是可行的。
In this paper we analyzed μC/OS-Ⅱtask scheduler,and pointed out its advantage and its problem to be improved.Based on the analysis,we extended μC/OS-Ⅱtask scheduler to make it support time-sharing scheduling and priority sharing,and the design of implementing the core algorithm of the task scheduler is proposed in this paper as well.Implementation showed that the extension on μC/OS-Ⅱtask scheduler is feasible.
