摘要
通用串行总线（ＵＳＢ）是一种正在迅速发展的高速外设总线，它具有热插拔、智能化、易于使用等特点。简要介绍了ＵＳＢ协议，讨论了ＵＳＢ技术的原理及其工作流程和实现技术，并结合ＵＳＢＮ９６０２芯片的结构及工作原理，阐述了ＵＳＢ接口电路的硬件设计过程和软件设计流程。
Universal Serial Bus (USB) is an emerging external bus employed in connecting peripherals with PC. The virtue of USB comes from its ability of being shared in essence. In USB system, the devices can be attached and detached without turning off the power supply. It is intelligent and expansive as well as apt to reduce the complexity of development of new peripherals. This paper presents USB protocol Revision 1. 1, the principle and implementing method of this bus . And according to the construct and principle of the chip USBN9602, the process of how to design the hardware and software of the USB interface circuit is described here.
