摘　　要：从系统的总体结构、硬件设计和软件设计3个方面阐述了USB2.0接口传输的FPGA控制与实现的设计方法。FPGA作为硬件设计中的主控芯片,完成了对USB接口芯片FT245R的通信控制、SRAM的读写操作等。通过USB驱动连接应用程序和底层硬件,实现了上位机中数据的发送、显示与存储。测试结果表明,FPGA通过USB接口实现了高速可靠的数据传输。The FPGA control of the USB2.0 transmission was expounded from the system architecture and the hardware and software design.The FPGA as a main chip in hardware design answers for communication control of FT245R interface chip and reading and writing the data to SRAM;and the connection between application program and underling hardware via USB driver can achieve dada sending and displaying and storage in the host computer.The results show that FPGA can benefit high-speed data transfer via the USB interface.
