摘　　要：针对Virtex-5 FPGA Aurora V5.3协议使用复杂和芯片成本高的问题,文中提出了一种采用Artix-7 Aurora V8.3协议进行高速图像传输设计的新方法。系统使用该协议,以AXI4-Stream作为内部链路进行高速数字图像的传输;利用PCI接口通过DMA技术实现了数据交互。用双路光纤传输图像数据进行测试,实验结果表明,传输速率为131Mbit·s-1,且稳定、可靠,为高速图像传输设计提供了一种思路。To address the complexity in using the Aurora VS. 3 protocol IP and the high cost of Virtex -5 FPGA chip, this paper introduces a new method of design of high - speed image transmission based on Artix - 7 Aurora V8.3 protocol. The system uses the Aurora V8.3 protocol and takes AXI4 - Stream as the internal link interface to design high - speed image transmission, realizing data interaction by the DMA control of PCI interface. Test of image transmission system with dual optical fiber shows that this method achieves stable transmission of correct data at a speed of 131 Mbit · s-1.
