摘　　要：USB具有传输速度快、成本低、可靠性高、支持即插即用等优点,且作为通用外设接口,有利于产品的升级换代。本文采用FTDI公司的FT2232H接口控制器,无需开发USB固件程序,充分利用芯片自身的两个独立配置接口,实现PC机对FPGA的在线配置和可寻址控制。该方法具有FPGA配置更新操作方便、数据寻址通信灵活、系统复杂度低和扩展性强的特点。USB(Universal Serial Bus)has good characteristics such as fast transmission,low cost,high reliability and supports plug and play.As a general peripheral interface,it is also beneficial to upgrade products.In the paper,FTDI’s FT2232H interface controller is fully adopted,the development of USB firmware programs is avoided,and two independent configuration interfaces of the chip itself are used to realize the online configuration and addressable control between PC with FPGA.This method has the features of easy operation of FPGA configuration update,flexible data addressing communication,low system complexity and high system scalability.
