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: RT-Thread RTOS，这是一款由国内RT-Thread工作室开发的开源实时操作系统。起初RT-Thread是一个实时的内核(全抢占优先级调度，调度器时间复杂度O(1))，但在发展过程中，RT-Thread实时操作系统得到了来自全国嵌入式开发工程师的鼎力支持，为RT-Thread添砖加瓦，现在它已慢慢变成一个完善的、全功能的操作系统：文件系统，网络协议栈，图形界面组件。。。只有您想不到，没有您做不到：RT-Thread是一个平台，您可以把您的创意汇聚在一起，小平台大社区，RT-Thread的开发人员就在您的身边。-RT-Thread RTOS, this is a studio by domestic RT-Thread operating system developed by open source real-time. At first RT-Thread is a real-time kernel (full preemption priority scheduling, scheduler, time complexity of O (1)), but in the development process, RT-Thread operating system by real-time embedded development engineers from the full National support and building blocks for the RT-Thread, now it has gradually become a complete, full-featured operating system: file system, network protocol stack, graphical interface components. . . Only you can not think without you can not do: RT-Thread is a platform, you can put your ideas come together, a small platform, large communities, RT-Thread of the developers on your side.

Description: 初次接触实时多任务操作系统的人，往往对实时程序的运行机制感到很困惑：任务在什么时候投入运行？操作系统以什么机制决定目前应该运行哪一个任务？本任务什么时候放弃了对CPU的控制？为了解答以上问题，我们从分析一个很简单的实时调度程序入手，来说明一下多任务程序的运行过程-Initial contact with real-time multitasking operating system, often real-time operating system program was very confusing: When does the task into operation? What mechanisms determine the current operating system to which a task should run? The task of the CPU when to give up control? To answer these questions, we analyze a very simple real-time scheduler to start, to illustrate the operation of the process of multi-task program Platform: |

Description: 这是一个基于命名管道的进程通信及调度程序框架的试验版本。一个solution中包含3个Project.其中，AppScheduling是进程调度程序（这个是将来可以使用的版本），TestJiuGong和TestPlayer分别是九宫格导航和播放器的简单模拟（将来会被实现真实功能的程序所替换。）
AppScheduling的功能：启动后自动隐藏窗口，启动九宫格导航。九宫格导航按1键后退出，启动播放器；播放器按0键后退出，启动九宫格导航；九宫格导航按0键后退出整个系统（包括AppScheduling）。
进程间通信采用命名管道，为实现多次通信，每次启动一个新的线程。-This is a process of communication based on named pipes and the pilot version of the scheduler framework. In a solution containing 3 Project. Which, AppScheduling is the process scheduler (this is the version used in the future), TestJiuGong and TestPlayer are squared simple navigation and players simulate (in the future will be achieved by replacing the real function of the program. ) AppScheduling features: auto hide windows startup, start squared navigation. Style Box Navigation exit Press 1 to start the player player press 0 to exit, start squared navigation squared navigation press the 0 key to exit the system (including AppScheduling). Inter-process communication using named pipes, for the realization of multiple communications, every time you start a new thread. Platform: |
