| 摘 要： | 在有大量的外部事件的计算机系统中，实时操作系统必须在有限的时间内接收和处理。这样的要求不是只有多道程序设计能满足的，还有实时操作系统一般是依靠一些特别的策略和技术来完成这些任务。Linux操作系统利用静态的可抢占的优先调度到大部分没有实时的多道程序设计系统中。作为一个在实时系统中的修改，优等权的分配是和每个任务的时间约束联系在一起的。本文阐述了Linux实时调度的几种机制。

| Abstract: | Real time operating system are used in environments where a large number of events, mostly external to the computer system, must be accepted and processed in short time with in a certain deadline. Such requirements usually cannot be met only by multiprogramming alone, and real time operating system usually relies on some specific policies and techniques for doing their jobs. Linux implements static priority-driven preemptive scheduling common to most non real-time multiprogramming system. As a modification in the real time systems, priority assignment is associated with the time constraint associated with each task.This article gives several scheduling of real-time Linux. |
