嵌入式FPGA在USB通信接口硬件设计中的应用

Application of Embedded FPGA to USB Communication Interface Hardware Design

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。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 computer field because of its high speed, versatility and plug and play. With the development of SOPC technology, FPGA becomes embedded CPU of system core from single function such as timing control, signal processing. A realization scheme to expand USB host and device based on embedded FPGA platform is designed, and the data transrhission function between USB host and USB devices is realized and verified.
