This paper expounds the cause of priority inversion problem and its effect for real-time system performance firstly, and then,two approaches named scheduler lock and priority ceiling protocol are employed inμC/OS-Ⅱfor reducing priority inversion phenomenon.

The second way is priority ceiling emulation.
第二种方法是使用优先级封顶模拟(priority ceiling emulation)。
This method also implements a form of priority ceiling. The ceiling is the priority of the server thread itself.
这个方法也实现了一类优先级提升。提升的优先级为服务线程自身的优先级。
Finally the Realtime Threads Feature Group adds mutex support for both priority inheritance and priority ceiling protocols.
最后,实时线程组为互斥锁支持了优先级继承协议和优先级天花板协议。
