摘　　要：USB总线具有传输速度高、通用性强和即插即用等特点，被广泛应用于计算机领域。随着SOPC（System—013一a—Programmable—Chip，即可编程片上系统）技术的发展，FPGA从完成单一的时序控制、信号处理逐渐过渡成为系统核心的嵌入式CPU。嵌入式FPGA平台对使用USB进行数据传输的需求也日益增多。本文设计了一种在嵌入式FPGA平台上扩展USB主机和USB外设的实现方案，实现并验证了USB主机和USB外设的数据传输功能。USB is widely used in the field of computer because of its high transmission speed, strong unive^ality and p｜ug and play. With the development of SOPC technology, FPGA is gradually transforming from single func- tion such as timing control, signal processing into embedded CPU of system core. The embedded FPGA platform demands that transmission data is carried out using USB are increasing. The paper designs a scheme for exten- ding the USB host and USB peripherals on the embedded FPGA platform. The data transmission function of the USB host and USB peripherals are realized and validated.
