摘　　要：以USB2.0接口芯片(Cy7c68013)为数据传输核心来控制网络芯片,数据包经由网络芯片编/解码,利用GPIF(通用可编程接口)异步传输Auto-In/Out(自动打包)接口和块传输方式,实现两台PC机的全双工通讯。该接口集成USB2.0和Ethernet(以太网)传输的特点,是一种高速、低延迟、远距离、使用灵活的传输方案。实验证明,传输速率可稳定在0.369MB/s。With USB2.0 interface chip （Cy7c68013） as main transmission unit to control a network chip, the data packet is coded and decoded by the network chip. The bulk transmission mode is adopted and the USB2.0 interface chip is configured in GPIF, asynchronous transmission, Auto-In operating interface mode. The duplex transmission between peer computers is accomplished in the paper. The both characters of the USB2.0 and the Ethernet transmission are integrated. It is a high speed, low delay, far distance and flexible transmission scheme. The testing result shows that the transmission speed can be up to 0.369 MB/s stably.
