dos 工具 用老版本的gcc编译，否则会出错(dos tools with older versions of THING)

一个虚拟DOS操作界面的小系统，一共有9条命令，可以在里面增加命令实现更多功能。(A virtual DOS interface small system, a total of 9 orders, which increased in order to achieve more.)

可以控制标签的各种状态，包括大小，字体等等，只要你能想到(Can control a variety of status labels, including size, fonts, etc., as long as you can think of)

操作系统文件管理实验：利用交互式命令实现树型目录结构和文件管理,同时利用位示图表示外存的分配情况，新建文件时分配必要的空间，模拟文件分配表记录文件在外存上的存储方式。了解系统对文件的操作。 在文件中保存目录内容，创建文件或子目录可以用命令行命令：MD、CD、RD、MK（创建文件）、DEL（删除文件）和DIR(Operating system file management experiment: the use of interactive command tree directory structure and file management, while taking advantage of the bit map indicates the distribution of the external memory, and allocate the necessary space when a new file is created, the simulation file allocation table log file is stored in the external memory way. Understanding of the system operation on the file. Save the contents of a directory in the file, create a file or subdirectory can use the command-line command: MD, CD, RD, MK (create a file), DEL (delete files) and DIR)

说明：  几个算法分析和操作系统的上机小程序，vc,c#实现(several algorithm analysis and operating systems on the plane small program vc, c#)

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.)

驱动调度+操作系统+模拟电梯调动的算法程序，使用C++编写。(Driven scheduling algorithm procedures, the+ operating system+ simulated lift mobilize written using the C++.)

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)

本教材以操作系统原理为主线，结合当今主流操作系统设计方法。(The principles of materials to the main line operating system, combined with today' s mainstream operating system design.)

说明：  ucos2 vc++移植代码 通过VC++编译，每2S显示一次任务(ucos2 vc++ code migration)
