基于FPGA的远程USB高速传输系统设计

摘要

提出了一种基于现场可编程门阵列（FPGA）的远程高速通用串行总线（USB）传输系统。FPGA作为一种实用的可编程器件,将其应用到USB传输系统中,并配合USB 2.0收发器和光纤传输模块,克服了USB硬件结构对其传输距离的限制,实现了USB远程高速透明传输,使系统传输速度达到480Mb/s,传输距离达10km以上,减少了开发周期,降低了风险。%This paper brings forward a long-distance high-speed universal serial bus(USB) transmission system based on field programmable gate array(FPGA).As a practical programmable device,FPGA is applied to the USB transmission system,and overcomes the limitation of USB hardware structure to its transmission distance cooperating with USB 2.0 transceiver and optical fiber transmission module,realizes the long-distance high-speed transparent transmission of USB,which makes the system transmission speed reach 480 Mb/s and the transmission distance exceed 10 km,shortens the development period,reduces the risk.
