摘　　要：针对现行USB2.0接口已不能满足现代大容量数据高速度传输需求,提出一种基于USB3.0和FPGA的高速传输的解决方案;该方案通过配置可编程接口把EZ-USB FX3设置成master主模式,优化DMA数据传输通道,实现了电脑与接口卡之间数据高速传输;文章详细地介绍如何提高传输速度的方法,经实际传输测试,该接口卡能在传输速率高达350 Mbyte/s依然能保持正确无误的高速传输。According to the fact that USB2.0 interface can＇ t meet the needs of high speed data transportation in the contemporary, this paper proposed a high-speed transportation based on USB3.0 and FPGA. This article designed a high speed interface card in master mode based on USB3.0, by optimizing of DMA data transmission channel, which are used to implement data transportation between PC and interface card with high speed. Through practical transmission test, the interface card can still able to maintain correct transmissions when the speed is up to 350 M byte/s.
