The computer system by use of electronic circuits and physical equipment, is almost tangible entities, such as the central processing unit, storage, an external device (input/output devices, I/O devices) and bus, etc.

硬件 计算机系统中所使用的电子线路和物理设备，是看得见、摸得着的实体，如中央处理器、存储器、外部设备（输入输出设备、I／O设备）及总线等。

The first device comprises an interface for sending an identification command to and receiving an identification message from the master device, and a processor for checking the identity of the second device and pairing the first device with the second device.

第一设备包括：接口，向主设备发送识别命令以及从主设备接收识别消息；以及处理器，检查第二设备的身份并将第一设备与第二设备配对。

Internal bus is a computer chip inside the external bus between the processor for use in chip-level interconnection; and system bus is the plug-in PC board and the bus between the system board for the interpolation pieces of board-level interconnection; external bus is between the computer and external equipment bus, microcomputer as a device through the bus and other equipment to carry out information and data exchange, and it is used equipment interoperability level even.

内部总线是微机内部各外围芯片与处理器之间的总线，用于芯片一级的互连；而系统总线是微机中各插件板与系统板之间的总线，用于插件板一级的互连；外部总线则是微机和外部设备之间的总线，微机作为一种设备，通过该总线和其他设备进行信息与数据交换，它用于设备一级的互连。

An I/O device suc h as a disk controller or LAN adapter runs at some speed and inserts enoug h wait states into the CPU bus to slow the processor down to match the device speed.

象一个磁盘控制器或局域网改编者那样的一台I/O设备以某速度运行并且插入足够等待状态进中央处理器总线减慢处理器匹配设备速度。

First, we analyse USB communication methods, and there are three important methods; Second, we discuss the whole software structure and communication protocols and design a basic protocol model based on embedded environment. Then, we explain the implementation of a file transport system based on this model. Through the comprehensive utilization of StrongARM UDC and Linux USB modules, we complete a portable protocol stack. Moreover, the function of the system is tested under the Windows and Linux OS.This thesis provides us with a full description on the realization of the USB mass storage system.

首先是USB系统通讯方法分析，将其归纳为三种主要的形式；然后论述了系统采用的的整体软件架构和通信协议体系，提出了基于嵌入式系统平台的协议栈的基本模型和具体内核实现机制，并阐述了基于此模型的文件传输系统的实现方法；最后，本课题通过综合运用StrongARM处理器上的USB设备控制器和Linux核心中提供的USB设备核心模块与字符设备模块，实现了一套可移植的USB海量存储设备类协议栈，并给出了系统在Widnows和Linux操作系统环境下的测试结果。

The Omnipaq is a device that combines a ticket printer with a 50-meter paper roll, a barcode scanner, a smart card and swipe card reader, a battery pack and a communications device-all connected to a central processing unit, which is a Compaq iPAQ 3630 with a CF-card sleeve.

Omnipaq是一种把标签打印机，50米长纸卷，条形码扫描仪，智能卡和读卡机，电池包以及一种通信设备全部整合到一个中央处理器上的设备。这种中央处理器就是带有闪存卡的Compaq iPAQ 3630。
