摘要
标准Linux是典型的分时系统,具有较差的实时性。随着Linux操作系统在实时应用领域的不断扩展,增强Linux系统的实时性变得尤为必要。以分析Linux内核调度策略及算法为出发点,从整个Linux系统的角度讨论了几种不同的增强Linux系统实时性的方法,并总结了当前Linux系统实时性研究的方向。
The standard Linux is a typical time-sharing system, it has a poor real-time performance. But according to the applications of the Linux OS are expanding on real-time domain, it becomes necessary to enhance the performance of the Linux system. This paper analyses the schedule policies and schedule algorithms of the Linux kernel, and discusses several different kinds of methods about enhancing real-time performance of the Linux system from the total Linux system. They authors summarizes the current research's developments of the Linux system.
