1．虚拟存储器的引入 局部性原理：程序在执行时在一较短时间内仅限于某个部分；相应的，它所访问的存储空间也局限于某个区域，它主要表现在以下两个方面：时间局限性和空间局限性。 2．虚拟存储器的定义 虚拟存储器是只具有请求调入功能和置换功能，能从逻辑上对内存容量进行扩充的一种存储器系统 (1. The introduction of virtual memory locality principle: program execution in a relatively short period of time limited to a particular part of it Accordingly, it has access to the storage space is also limited to a particular region, it is mainly manifested in the following two aspects: the time limitations and space limitations. 2. The definition of virtual memory Virtual memory is just a request for redeployment of functions and displacement functions, from the logical to expand the memory capacity of a memory system)

一个微型操作系统源码。抛砖引玉，希望有更多的国人开发和共享操作系统源码。(a micro-source operating system. Comment hope more people development and sharing of the operating system source code.)

说明：  simulink燃气轮机模型 可进行仿真(simulink gas turbine LM2500)

说明：  用标准C实现shell功能,是操作系统的作业，Linux里面的she(Shell to achieve using standard C function, the operation is the operating system, Linux inside she)

简单的文件系统试验源代码，可用于操作系统的大型实验~~(Simple test source code of the file system, the operating system can be used for large-scale experiments to ~)

说明：  一个forth语言的开发环境，既是语言又是操作系统。forth语言很好大家可以接触下试试(A forth language development environment, only a language but also the operating system. forth under the language of good contacts we can try)

用ADS开发的2440程序,并且有UCOS2操作系统(With the the ADS development of 2440 program)

用STM32与AD7124设计用于测温的系统(STM32 and AD7124 tempreture control)

加深进程概念的理解；掌握选择进程调度算法的准则；掌握进程调度算法。 (Deepen the process of understanding of the concept master scheduling criteria selection process algorithm master process scheduling algorithm.)

操作系统实验演示代码(三个实验，作业管理，内存管理，文件管理)(Experimental demonstration of the operating system code (three experiments, operations management, memory management, document management))
