本次程序的题目为：进程管理――支持多个进程并发运行的简单的进程管理模拟系统，对本实验的分析要求是：⑴系统中的同步机构采用信号量上的P、V操作的机制；⑵控制机构包括阻塞和唤醒操作；⑶时间片中断处理程序处理模拟的时间片中断；⑷进程调度程序负责为各进程分配处理机；⑸根据用户的需求来创建n个进程(n为即满足用户需求,又不超出系统可容的最大进程数),各进程互斥地访问使用临界资源 S1、S2；⑹使用动态优先数(如：随阻塞次数的增加而减小优先数，以提高其优先权)；⑺进程结束后应能够撤消；⑻进程间能实现“发送”和“接收”两个消息缓冲通信操作；⑼系统在运行过程中随机打印出各进程的状态变换过程、系统的调度过程及公共变量的变化情况，在一个进程运行完毕，进入完成状态后，可以将该进程撤消，也可以动态的创建另一个新的进程。-the procedures on the topic of : process management-- to support multiple concurrent processes running a simple process management simulation system for the analysis of the experimental requirements are : 1 system of institutions using synchronous signals on the amount of P, V operation of the mechanism; 2 control agencies, including obstruction and awaken operation ; 3-time interrupt handling procedures-time simulation of interruption; 4 process scheduler is responsible for the allocation process processors; together according to the user"s needs to create process n (n that meet user needs, without exceeding the system can accommodate

线程同步机制。 互斥器的功能和临界区域很相似。区别是：Mutex所花费的时间比Critical Section多的多，但是Mutex是核心对象(Event、Semaphore也是)，可以跨进程使用，而且等待一个被锁住的Mutex可以设定TIMEOUT，不会像Critical Section那样无法得知临界区域的情况，而一直死等。-Thread synchronization mechanism. Mutex" s function and the critical region is very similar. The difference is: Mutex spent more time than the multi-Critical Section, but the Mutex is the core object (Event, Semaphore is), you can cross-process use, and has been locked waiting for a Mutex can be set to TIMEOUT, not as Critical Section did not know the critical situation in the region, for so long and so die.

页式虚拟存储管理中地址转换和缺页中断，这是赏完操作系统课时做的实习设计，有完备的分析余与设计，如实验目的，实验内容，实验模块的实现，采用的是采用先进先出页面置换算法。-Page storage management in virtual address translation and page fault, which is the operating system rewards End internship hours to do the design, there are more than a complete analysis and design, such as experimental purposes, the experiment content, laboratory module, used in the application of advanced first-out page replacement algorithm.
