摘　　要：针对100fps的帧率、600×400图像尺寸16位灰度CMOS图像传感器的大数据量远距离传输关键技术问题。借助于用户数据报协议(UDP)作为通信协议,采用XC6SLX16FPGA对图像传感器采集的数据进行预处理及将图像数据封装成以太网帧,同时配合专用的千兆以太网PHY芯片VSC8601,通过RGMII接口进行FPGA与PHY的连接方式,设计了一种基于FPGA的千兆以太网CMOS图像传感器数据传输系统。实验测试结果表明,该系统不仅实现了530 Mbit/s的高效可靠图像数据的远距离传输,而且该系统安全可靠,能够稳定有效工作。According to the key technical problems of 100 fps framerate and 600×400 image size and 16 bits CMOS image sensor＇s long distance and large data transmission. Using user datagram protocol as a communication protocol, the data that image sensor collected is not only preprocessed, but also packaged into Ethernet frame by XC6SLX16 FPGA. At the same time, using a dedicated gigabit Ethernet PHY chip, the connection interface between FPGA and PHY in RGMII interface, design a gigabit Ethernet transmission system of CMOS image sensor data based on FPGA. The experiment test results show that the system can achieve 530 Mbit/s transfer rate, and the transmission data is reliable, the system not only is safe and reliable, hut also can work efficiently.
