摘　　要：系统数据传输速度很大程度上影响着大型显示屏的视频显示效果。为了有效增加系统数据传输量,提高系统资源利用率,设计了一种基于Aurora协议,通过光纤通信实时传输视频数据的系统,该系统由SFP光模块与Xilinx公司Spartan6系列现场可编程门阵列(FPGA)芯片配合使用,利用AuroraIP核实现高速串行通信。进一步提出通过修改IP核代码,充分利用同一收发器中的2条通道,使SFP光模块2个端口单独工作的方法,从而达到SFP光模块级联的效果。最终通过电路板实物实时观测系统远距离传输上位机视频数据的效果,实验结果证明了系统数据传输的可行性与稳定性。The system data transfer speed largely affects the video display of large displays. In order to effectively increase the amount of system data transmission and improve the system resource utilization, a system based on Aurora protocol for optic fiber communication to transmit video data is designed. The system combines SFP optical modules with Xilinx Spartan6 series field-programmable gate array(FPGA) chips, and uses the Aurora IP core to achieve the high speed serial communication. Furthermore, by modifying the IP core, and using the two lanes in one transceiver to make the two ports of the SFP optical module work separately which achieve the effect of cascading SFP optical modules. Finally, the experimental results of real-time long-distance transmission of the video data of the host computer by circuit board prove the feasibility and stability of the system.
