Research on reducing priority inversion problem in real-time control systems

Bases on the real-time operating systemμC/OS-Ⅱ,this paper analyses the reason that priority inversion bechanced and then gives exposition how to adjust this problem by mutual exclusive semaphores and time slice.On the precondition,of ensuring mutex visiting of the shared resources,the proposed approach limits the occurrence of priority inversion on one level,and alleviates the priority inversion phenomenon occurrence inμC/OS-Ⅱ.
