基于千兆以太网的高速图像数据传输系统实现

针对高速图像数据传输的实际需求设计了一种基于千兆以太网的大容量数据高速传输设计方案。该方案根据实际需求充分利用FPGA可重构性的优势,实现了以UDP协议为基础的自定义全双工MAC核,其优化的命令接收模式在接收端绕过了TCP/IP协议降低了FPGA端协议解析的复杂度与硬件开销；其流量可控并带有重传机制的数据上传模式可以与不同配置、不同工况的上位机稳定可靠高效率传输。实际最高传输速率达到稳定的49MB/s,性能优越。

Implementation of high-speed image data transmission systembased on Gigabit Ethernet

A new high speed transmission design scheme based on Gigabit Ethernet is proposed for high-speed data transmission . According to the practical requirements of the scheme , the advantages of FPGA can be reconstructed , and the full duplex MegaCore based on UDP protocol is realized . The optimized command receiving mode reduces the difficulty of the FPGA to unpack the data and reduces the hardware resource consumption by the way of bypassing the TCP/IP in the receiving end . The data upload mode with speed controllable and re-transmitting can be stably and reliably transmitted in different configurations and different operating modes of host computer . The actual maximum transmission rate reached stable 49MB/s , has obviously more advantage .
