基于Verilog的FPGA与USB2．0高速接口设计

Design of High Speed Interface FPGA and USB 2.0 Based on Verilog

USB 2.0接口芯片FX2 CY7C68013工作在Slave FIFO模式下,讨论了一种以FPGA为控制核心,对其内部的FIFO进行控制,以实现数据的高速传输。该系统模块主要由USB固件程序和FPGA控制软件组成,可应用到需要通过USB 2.0接口进行高速数据传输或采集系统中。实验结果表明:系统具有数据传输准确、速度快等特点。

In this paper, high speed data transmission technology which used Slave FIFO pattern of USB 2.0 FX2 CY7C68013 under the control of FPGA is introduced. The system mainly consists of two parts of firmware design program and software of control of FPGA. It can be applied to those systems which need to transmit or acquire mass data quickly by USB 2. 0 interface. The result of examination indicates that the system is exact in transmission and high in speed.
