基于VHDL的USB2.0协议处理层的设计与实现

Design and Realization of USB 2.0’S Protocol Layer Based on VHDL

随着计算机各种软硬件的升级和发展,由于USB(UniversalSerialBus,即通用串行总线)的热插拔、即插即用、共享式小巧接口、成本低、使用灵活、性能可靠、兼容性好等一系列优点,使得它迅速成长,成为各种操作系统、控制芯片和开发工具支持的一种标准接口。可编程逻辑器件随着计算机技术的发展也越来越得到广泛的应用。本文在此主要通过VHDL语言,利用可编程逻辑器件作为载体来设计USB2.0的协议处理层模块。

Along with the promotion and development of all kinds of software and hardware of computer,USB （namely Universal Serial Bus）,for a series of merits of it ,such as the hot plug, plug and play,the sharing type dapper interface ,the low cost ,the mobile use,the reliable performance,the good compatibility and so on,has been grown rapidly and becomes one of the standard interfaces,which many operating systems,controlling chips and development tools support .the programmable logical devices are applied widely with the development of computer technology as well,This paper mainly talks about designing the protocol layer of USB2.0 with the programmable logical device as the carrier through the VHDL language.
