Description: 模拟进程调度的C语言实现
一、 实验目的
体会UNIX 系统的进程调度方法，并通过一个简单的进程调度模拟程序的实现，加深对进程调度算法，进程切换的理解。
二、 实验内容
采用静态优先数的方法，编写一进程调度程序模拟程序。模拟程序只对你所设置的“虚拟PCB”进行相应的调度模拟操作，即每发生“调度”时，显示出当前运行的“PCB名字”、优先数、运行时间等，而不需要对系统中真正的PCB等数据进行修改。-C UNIX Two experimental use of static content priorities in a way, to prepare a process scheduler simulation program. Simulation program only right you have set up a "virtual PCB" accordingly scheduling simulation operation, that is, each occurrence "Dispatch" shows that the current operation "PCB name" priority number, running time, without the need for a real system, such as PCB data changes.

Description: 1. 最早截止时间优先EDF（Earliest DeadlineFirst）算法是非常著名的实时调度算法之一。在每一个新的就绪状态，调度器都是从那些已就绪但还没有完全处理完毕的任务中选择最早截止时间的任务，并将执行该任务所需的资源分配给它。在有新任务到来时，调度器必须立即计算EDF，排出新的定序，即正在运行的任务被剥夺，并且按照新任务的截止时间决定是否调度该新任务。如果新任务的最后期限早于被中断的当前任务，就立即处理新任务。按照EDF算法，被中断任务的处理将在稍后继续进行。
-1. The first priority deadline for EDF (Earliest DeadlineFirst) algorithm is a very famous one in real-time scheduling algorithm. In every state of readiness for a new, scheduler from those already in place but has not fully dealt with the mandate to select the earliest deadline for the task, and the implementation of the tasks required for the allocation of resources to it. In the arrival of new tasks, the scheduler must immediately calculate EDF, from the new sequencing, that is the task of running was curtailed, and new tasks in accordance with the deadline for deciding whether to dispatch the new tasks. If the new mission as early as the deadline for the immediate task was interrupted immediately to deal with new tasks. In accordance with the EDF algorithm, the task was interrupted to deal with will be at a later date to continue. Platform: |

Description: By Le Trung Thang,April 2012
By default, the Linux kernel build used in the many open source distributions is the normal/default kernel which doesn’t support real time scheduling. If an embedded developer wants to compare the scheduling policies of Linux to a real time operating system it is more useful to compare RTOS performance to a version of Linux that does have real-time features.
Fortunately, in addition to this default kernel, there is also available a Real-time kernel version that supports a real-time scheduling policy. In this article and in the code examples that are included, an effort is made to compare the real time operations of standard and real-time Linux with normal RTOS operation and evaluate the differences and similarities.
