摘要
Linux是一种通用操作系统,但不适合实时应用。针对上述问题,通过对Linux时钟系统管理方面的研究,提出一种针对时钟的改进策略,以此为基础,根据实时应用的特点设计高精度定时器。实验证明,改进方案能有效提高Linux的时钟精度,满足实时方面的需求。
Linux is designed to be a general-purpose operating system, it is not suitable for real-time applications, but because of its open source, many solutions have been put forward to enhance its real-time ability. Inspired mostly by Gettimeofday(GTOD), the paper gives a method based on timer management improvement for high resolution timers. Experiments on the modified OS show that the improvement gives a better result for applications with real time constraints than original Linux kernel.
