USB协议栈的设计及其在嵌入式领域的应用

Design of USB Protocol and the Implementation of Relavtive Applications in Embed System

USB已经成为一种非常成功的总线标准。以USB在一个嵌入式系统的实现案例,介绍了USB总线的硬件研发过程及相关USB协议栈的设计与实现,并且探讨了在嵌入式操作系统中基于该协议栈的USB设备驱动的开发以及USBBiosBootRom的设计。

Using the case of an USB realization in an embeded system,this paper introduces the hardware design of USB and implementation of the relative USB protocol stack.Using this USB protocol stack,this paper accomplishs a USB Flash Disk driver for real-time DOS and a USB BIOS Boot ROM,which gives an example on how to utilize this USB protocol stack to develop projects for embeded systems.
