Priority inversion is the most problem in the real-time system.At present,priority inheritance and priority ceiling are often adopted to prevent the phenomenon of priority inversion.However,the two ways have some disadvantages in a given situation.So fault-tolerant is adopted to improve the reliability of the system.This paper expanded priority inheritance based on fault-tolerant to allow a better solution to the problem of priority inversion and ensured the real-time performance of the real-time system.
