Linux的雏形，也就是Linux的创始人公布的最初代码。 现在各种分析Linux的书太多了，但对于初学者来说都过于复杂，难以理解，这个最初版本相对来说要简单多了，但一样可以让我们了解Linux的基本实现过程，大小只有70多K-Linux prototype, is the founder of Linux announced the initial code. Now, all kinds of analysis of the Linux too many books, but for a newcomer are too complicated to understand, the initial version to be relatively more simple, but you can help us understand the basic realization of Linux process, the size of only 70 K

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

easyVM是一个虚拟机，模拟了8086及一些简单外设，可以跑MS-DOS 6.22。 是一高校毕业设计作品。 在看雪论坛上置顶精华，是不可多得的研究虚拟机的参考资料和代码实现。-easyVM is a virtual machine, to simulate the 8086 and some simple peripherals, you can run MS-DOS 6.22. Is a college graduate design work. Watching the snow Forum Top essence, is a rare study of the virtual machine and code reference implementation.
