摘　　要：USB(通用串行总线)控制器CY7C68013因其数据传输速率快和多样的接口方式为ATA、FPGA(现场可编程门阵列)和DSP(数字信号处理器)等提供了简单和无缝连接接口而得到广泛使用,介绍了此控制器与FPGA接口的控制和HDL(硬件描述语言)实现方法。利用CY7C68013控制器的Slave FIFO从机方式,用Verilog HDL在FPGA中产生相应的控制信号,实现对数据的快速读写。试验结果表明此方案传输速度快、数据准确,可扩展到其他需要通过USB进行快速数据传输的系统中。The USB controller CY7C68013 is used widely because it has faces such as ATA, FPGA and DSP and so on. The paper introduces how CY7C68013 and FPGA by hardware description language （HDL）. By means quick speed and various interto implement the interface of of CY7C68013＇ s Slave FIFO, we create controllable signals in FPGA in Verilog HDL and realize to read and write data quickly. The result of examination indicates that the system is quick and exact, and it can be applied to those systems that need to transmit a lot of data quickly by USB interface.
