【摘要】 随着Linux操作系统的成功,改进Linux的设计和性能,使其应用于实时领域受到了越来越多人的关注。考虑到Linux目前的时钟粒度仍然粗糙,它将直接影响到整个内核的实时性能,文中提出了一种基于Linux操作系统下时钟系统的改进机制,找出修改时钟系统提高实时性的具体方法。实验结果显示,所作改进以不大的代价有效地提高了Linux的实时性能。更多还原

【Abstract】 Along with the success of Linux,how to improve Linux performance and to satisfy real-time requirement appeales more and more intension of developers.Because Linux timer granularity is granulated,it can affect real-time capability of entire kernel immediately.In this paper,put forward the improvement mechanism of timer system based on Linux operation system,find out the method of modifying timer system and enhancing real-time capability.Experiment result shows it is effective to improve Linux real-time capability by lower cost.更多还原
