| Abstract: | 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. |
