摘　　要：USB接口以其即插即用、安装方便、高带宽、易扩展、传输速度快等优点,在PC及其外围设备接口中得到了普遍的应用,但其实际传输速度远远达不到理论上的最高速度。本文设计了一个以FPGA为主控制器,以CY7C68013A为接口芯片的数据采集系统。接口芯片工作在GPIF主控模式下,保证了数据传输的高速度,FPGA作为数据处理模块,保证了数据的正确性,从而使系统可以实现高速准确的数据传输。本系统所能达到的最高数据传输速度为37Mb/s。USB interface has the advantage of plug—and-play,easy to install,high-bandwidth,easy to expand and high-speed transmission,the PC and its peripheral device interface is being widely application,but the actual transmission speeds are far less than the top speed in theory.The article introduces the design with FPGA as a central controller and CY7C68013A as a interface chip in this system.The interface chip works in GPIF mode,ensure the high speed of data transmission,FPGA as the data processing module,ensure the correctness of the data,so that the system can realize the accurate and high speed data transmission.The system can reach the highest speed of data transmission to 37 Mb/s.
