摘　　要：Applications with real-time constraints are not only growing in the field of embedded system,but gainingpopularity in the desktop environment as well. At the same time, using an opened source system,Linux,as the sup-ported OS is more and more appealing to many developers. So it is regarded as a potential aspect by many users to im-prove Linux performance to satisfy the real-time requirements. The article discusses the mutex implementation ofLinux in depth and on the basis of that, gives rise to methods to improve the deficiency. An implementation underversion of 2.2 series is brought forward.Applications with real-time constraints are not only growing in the field of embedded system,but gaining popularity in the desktop environment as well.
