μC/OS-Ⅱ动态任务优先级调整机制初探

Preliminary Study on Dynamic Task Priority Adjustment Mechanism of μC/OS-Ⅱ

动态任务优先级调整机制可让嵌入式系统运行时灵活切换工作模式,对μC/OS-Ⅱ动态调整任务优先级的任务管理机制进行了深入探讨,并基于PC机Win/XP系统下的DOS命令窗口(cmd)模式给出了应用实例,接着对实例的运行结果进行了测试与分析,最后对该机制可能的应用场景进行了初步探讨,拓宽了μC/OS-Ⅱ内核的应用领域。

This paper discusses the task management mechanism of μC/OS-Ⅱ dynamic task priority adjustment in depth,and an application example is given based on the cmd mode under PC Win/XP system.Then operation results of the application example are tested and analyzed.Finally,the possible application scenarios of the mechanism are discussed.The mechanism broadens the application field of μC/OS-Ⅱ kernel.
