Design of high speed image transmission based on Gigabit Ethernet

摘要:

针对以太网技术在高速图像传输中常见的带宽利用率低,传输协议受限的问题,设计了一种基于可编程逻辑器件FPGA实现千兆以太网传输系统的方案,分析了基于IEEE802.3标准的以太网帧格式和循环冗余校验(CRC),实现了MAC数据包的封装和PHY芯片88E1111的配置,完成了千兆网络系统的设计和高速数据的传输。结果表明,该方案具有成本低,传输速率快且传输协议不受限制的优势,并最终成功应用于某水下高速图像传输系统中。

Abstract:

For resolving common problems when Ethernet technology is applied in the high-speed image transmission, such as low utilization rate of bandwidth and limited transmission protocol, The article designed a gigabit Ethernet transmission system based on programmable logic device FPGA , analyzed the Ethernet frame format based on the IEEE802.3 standard and the Cyclic Redundancy Check (CRC), implemented the MAC packets encapsulation and the PHY chip (88E1111) configuration. Results show that the scheme has the advantages of low cost,Sfast transmission rateSandSunlimited transmissionSprotocolSand ultimately successful application in an underwater high-speed image transmission system.
