摘　　要：选用支持USB2.0高速数据传输的CY7C68013芯片,设计实现PC与硬盘驱动器串行数据传输的PnP(即插即用)模块。将CY7C68013的GPIF(通用可编程接口)与标准的IDE硬盘接口相连,PC与USB接口通信采用BULK(批量传输)方式,USB接口与硬盘通信采用PIO(通用可编程输入输出)和UDMA(超级直接存储器存取)两种模式,达到了USB2.0的高速率传输要求。In this paper, the PnP(Plus and Play) module of the serial data transfer between PC and HD is designed and implemented by the CY7C68013, according with the high speed of USB2.0. The GPIF(General Programmable Interface) of CY7C68013 is connected with the HD of the standard IDE physically. The BULK(Batch Transfer) mode is adopted to communicate between PC and USB interface,while PIO(Programmable I/O) and UDMA(Ultra-DMA) mode between USB interface and HD. The system’s transaction has well settled for the high speed of USB2.0.
