摘　　要：优先级继承协议和天花板优先级协议都可在一定程度上解决实时系统(RTOS)中的优先级倒置。文中讨论在嵌入式实时操作系统μC/OS-II中的优先级倒置问题。通过对比选择合适的优先级天花板协议进行详细的系统分析设计,在μC/OS-II应用中避免优先级倒置问题。Both priority inheritance protocol and priority ceiling protocol are common solutions to priority inversion in real- time system （RTOS）. Discuss the priority inversion in the real- time system named μC/OS-Ⅱ. To compare the two solution and good analysis for choose and design to avoid priority inversion in the use of μC/OS-Ⅱ.
