Description: 针对操作系统进行二级目录文件系统的模拟 用disk.txt模拟硬盘，设定硬盘容量分为100个物理块，每个物理块的大小512字节，盘块之间用(‘\n’)分割。
因此一个盘块：512字节数据＋1字节(‘\n’)分割符＝513字节，则disk.txt 长度＝51300（ 100×513 ）＋1字节（文件结束符）＝51301字节 。
-Secondary directory for the operating system file system simulation using simulation disk.txt hard drive, hard drive capacity set is divided into 100 physical blocks, each physical block size of 512 bytes, between the disk block ( ) partition. Thus, a disk block: 512 bytes of data 1 byte ( ) partition Fu = 513 bytes, then disk.txt length = 51300 (100 × 513) 1 bytes (at end-of-file) = 51,301 bytes.

Description: 随着计算机技术的不断发展，USB设备以其传输速度快、可热插拔、独立供电等诸多的优点被普遍采用。现在市面上的USB设备层出不穷，如U盘、MP3、移动硬盘等应用起来十分方便。
本文采用VisualC++6.0软件进行仿真，利用基于对话框的VC++应用程序完成对上位机界面的编写，可以利用VC编程实现对计算机底层硬件的操作。采用DriverStudio软件编写USB设备的驱动程序。
本文先介绍了USB通信协议及其传输方式，然后具体地给出了驱动程序开发的全过程，同时根据硬件电路设计了上位机显示界面，并对各个显示元素的功能及编码过程做了详细的介绍。在上位机软件可以正常运行后，把USB实验板连接到电脑，进行PC机与USB设备的相互通信，结果表明，在通信的过程中，可以完成PC机与USB设备的连接和相互控制。- As computer technology continues to develop, USB devices is being widely used for its fast transmission speed, hot-pluggable characteristics, independent power supply and many other advantages. Nowadays, endless USB devices, such as FLASH MP3, mobile hard disk and so on, influx the electronic market, bringing extreme convenience for people’s daily lives.
The simulation environment in this thesis is constructed by VisualC++6.0 software. We use VC++ application process to complete the preparation of the PC interface, and based on the VC programming we can operate of the hardware of the computer bottom. On the other hand, we use DriverStudio software to prepare the driver of USB device.
In this thesis, we introduce a USB communication protocol and the means of its transmission, and then give the entire design process of the driver specifically. Meanwhile, according to the hardware circuit, we design the shows PC interface and show the function and the coding process of each element i

Description: 我编写的文件系统模拟程序。
运行程序后，在左端控制面板可以进行格式化，打开已有目录文件和保存目录文件功能，在中间的树形目录中，可以选中文件或文件夹，进行重命名，新建，删除等等工作,双击选中项可以直接打开文件。
整个磁盘空间被划分为了三个部分：索引，FAT，和数据块Block。
对于空闲数据块的管理，使用的是位图的方法，每个Block对应一个FAT结构，FAT中存放了该Block的信息和下一个关联Block号。
文件目录采用了多级目录结构，并建立了索引。
-I prepared the file system simulation program. After running the program, in the left control panel can be formatted, open the directory file and preserve the existing directory document function, in the middle of the directory tree, you can select files or folders, rename, create, delete, etc. work, double-click the selected item to open the file directly. The entire disk space is divided to three parts: the index, FAT, and data block Block. File directory using a multi-level directory structure, and the establishment of the index.
