摘　　要：为满足数据传输系统对远距离、大量数据、抗干扰性和可靠性的需求,提出了一种基于FPGA的千兆以太网传输以取代以往的百兆网传输方式,实现大数据的快速远距离传输。FPGA接收到数据后通过FIFO缓存,经过FPGA组帧后通过超五类双绞线传输。系统传输速度最高可达1 Gbit·s^(-1),硬件完成对数据的采集、校验和发送控制。经过仿真、调试、验证,系统数据流速度可以稳定在800 Mbit·s^(-1)以上。A Gigabit Ethernet transmission based on FPGA is designed to replace the existing 100 M Ethernet FPGA for real - time reliable long - distance transmission of large data. The data received by FPGA are cached in the FIFO for FPGA group frame and then transmitted through the cat5e of twisted pair at a speed of up to 1 Gbit · s -1 Data acquisition, processing, and transmission control are implemented by hardware. Simulation shows the transmission speed of the system remains stable at above 800Mbit · s-1
