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Lnux的实时性能
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
