一种解决μC/OS中优先级反转问题的方案

A Solution and Implementation of Priority Inversion Problem of C/OS

针对实时系统中的优先级反转问题,提出了一种采用优先级继承机制来解决优先级反转问题的方案,并给出了在μC/OS中的实现。该方案基于互斥信号量,描述了相应的数据结构和主要算法并对算法作了简要的分析。

The real-time system has latency priority inversion problem, inherence mechanism and give a implement in μC/OS system. The architecture of the solution is described. this paper described a solution of this problem using priority solution is based on a mutex semaphore and the algorithm architecture of the solution is described.
