计科操作系统课程“读者写者”问题的经典解决。(Branch of the operating system programs, " wrote the reader" as a problem to solve classic.)

用纯C语言编写的一个Linux下的Shell，包含tch和bash的基本功能（包含重定向和后台运行），暂时不支持管道。已经在cygwin和Ubantu 7.10下测试通过。 主要包含： makefile 编译生成myshell可执行文件 myshell.c 主函数（涉及程序入口） utility.c 所有功能函数（将近1000行） myshell.h（包含宏定义、结构体声明、库函数的头文件，及utility.c中的所有函数的声明） readme 用户手册（当用户在myshell里输入help <command> 时，输出<command>的使用说明） (With pure C language under Linux in a Shell, contains tch and bash the basic functions (including redirect and running in the background), the moment does not support the pipeline. Has been under cygwin and test Ubantu 7.10. Mainly includes: makefile compiler generated executable file myshell main function myshell.c (relating to procedures for entrance) utility.c all the features of function (nearly 1000 lines) myshell.h (contains macro definition, the structure declaration, the first document library, and all utility.c statement function) readme user' s manual (when users enter help in myshell <command> , The output <command> The use of explanation))

在采用多道程序设计的系统中，往往有若干个进程同时处于就绪状态。当就绪进程个数大于处理机数时，就必须依照某种策略来决定哪些进程优先占用处理机。本实验模拟在单处理机情况下的处理机调度，帮助学生加深了解处理机调度的工作。 二、实验类型 设计型。 三、预习内容 预习课本处理机调度有关内容，包括进程占用处理机的策略方法。 四、实验要求与提示 设计进程调度算法，进程数不定；包含几种调度算法，并加以实现；输出进程的调度过程——进程的状态、链表等。要求使用优先权法和轮转法模拟进程调度过程。 【提示】：简化假设 1） 进程为计算型的（无I/O） 2） 进程状态：ready、running、finish 3） 进程需要的CPU时间以时间片为单位确定 【提示】：算法描述 1） 优先权法——动态优先权，当前运行进程用完时间片后，其优先权减去一个常数。 2） 轮转法 (err)

Microsoft MS-DOS6.0 完整源代码，包括所有外部命令，安装程序，DOSSHELL等。每个源文件均包括开发历史、更新说明、注释。这样一套源码对你的意义，实在无法以笔墨形容(Microsoft the MS-DOS6.0 complete source code, including all external commands, the installation procedure, DOSSHELL and so on. Each source document includes the development history, the renewal explanation, the annotation. This kind of set of sources code to your significance, really is unable to the words to describe )

于渊的 一个操作系统的实现 光盘源码 第五章和第六章 该源码包含了操作系统实现的完整过程(In a deep realization of the operating system CD-ROM chapters V and VI of the source code contains the operating system to achieve the complete process)

说明：  消费代码.用于操作系统中的课程设计使用.愿大家提供建议我也好改进算法(Consumer code. For the operating system to use the curriculum design. I would like to provide recommendations to improve the algorithm or)

操作系统实验教程——核心技术编程实例。包括中断处理，文件管理等具体实例。主要采用汇编语言。(Experimental tutorial operating system- the core technology programming examples. Including interrupt handling, document management, such as concrete examples. The main use of assembly language.)

钟毓秀操作系统课后习题答案,有详细的计算题答案4-8章(Operating after-school exercise钟毓秀answer questions have detailed answers to the calculation of Chapter 4-8)

现在有很多相机类型，有的鱼眼相机照完的图片会发生畸变，为此，我们要进行鱼眼图片校正。本程序正是针对鱼眼图象的校正程序，里面有详细的注释说明相信只要是有一定的基础的人都能看懂。不过，还有差值部分没做完哪，有待完善。(Now have a lot of camera types, and some fish-eye camera images will be finished according to distortion, to that end, we have to carry out fish-eye image correction. This procedure is for fish-eye image correction program, which has detailed notes as long as it is believed that the basis of a certain person can understand. However, there is some difference which did not finish, remain to be improved.)
