模拟操作系统对内存分配和释放的四种情况。用户可以自行设定将要分配和释放的内存大小来查看相应的结果。(Simulation of the operating system on memory allocation and release of the four types of circumstances. Users can set their own distribution and release to the memory size to see results.)

经典问题魔兽世界（wumpus world）的程序，还比较简单，只能在dos下文字表示，没有图示(classic World of Warcraft (chat world) procedures, but also relatively simple, only under the dos text, there is no icon)

操作系统作业源代码，方便学习操作系统课程的同学使用 (this is the codes for students who learn computer system.)

UG开发代码,开发型材的代码,UG对话框的源文件,可以参考(UG)

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

简单写字板，精选ios编程学习源码，很好的参考资料。(Simple WordPad, selection of learning IOS programming source code, a good reference.)

1）设计一程序，由一个进程创建三个子进程，三个子进程一个是生产者进程，两个是消费者进程。 2）父子进程都使用父进程创建的共享存储区进行通信，由生产者进程将一个数组中的十个数值发送到由5个缓冲区组成的共享内存中。? 3）两个消费者进程轮流接收并输出这十个数值，同时将两个消费者进程读出的数值进行累加求各和。 4）考虑生产者进程生产的速度和消费者进程速度。(1) a program is designed to create three sub processes from one process, three sub processes is the producer process, and the two is the consumer process. 2) the father child process communicates with the shared storage area created by the parent process, and sends ten values in one array to the shared memory composed of 5 buffers by the producer process. L 3) the two consumer processes take turns to receive and output the ten values, and add values to each of the two consumer processes. 4) take into account the production speed of the producer process and the speed of the consumer process.)

内存静态分配： 程序还有一些错误，益出处理不知道怎么加入。此程序开始不是我写的的，我在别人的基础上理解并改动了一些。实验课已经结束了，没时间在做了，以后有机会再改。(static memory allocation : there are some procedural error, derived from processing do not know how to join. This is not the beginning of the proceedings I write, I others on the basis of understanding and change some of it. Experiments over, and no time to do in the future will have the opportunity to change.)

对于OPT算法，在有多个页面可选的情况下，先淘汰较早进入的页面）。 3. 计算缺页次数及缺页率。 测试用例格式如下： 输入： 算法（1 OPT，2 FIFO，3 LRU） 内存块数 页面序列（页面1,页面2,页面3,...) 输出： 页面变化时内存块装入页面列表1-是否命中/页面变化时内存块装入页面列表2-是否命中/... 缺页次数 其中： 页面变化时内存块装入页面列表：内存块1装入页面,内存块2装入页面,内存块3装入页面...，未装入任何页面时由 -”表示 是否命中：1-命中，0-缺页">

处理及调度源代码，用C++来编程，模拟处理机调度，实验报告(Processing and scheduling source code, using C++, programming, analog processor scheduling, lab reports)
