摘要:

千兆以太网在工程上的应用越来越迫切,许多快速可靠的数据传输任务要依靠其完成。文中提出了一种多通道数据采集系统设计方法,将采集的数据通过FPGA资源搭建的千兆以太网运行环境发送到上位机进行显示和存储,最大限度地发挥了FPGA和千兆以太网灵活与快速的优势。进而讨论了ARP包和Jumbo帧的相关问题,并实际测试了其对系统的影响。

关键词: 千兆以太网, UDP/IP协议栈, DDR2 SDRAM, Jumbo帧

Abstract:

Applications of Gigabit Ethernet in engineering are becoming increasingly urgent,and fast and reliable data transmission work relies mostly on Gigabit Ethernet.This paper presents a design of multi-channel data acquisition system.The system sends collected data to a host computer for displaying and storage via Gigabit Ethernet operating environment constructed by FPGA resources,which takes full advantage of their flexibility and rapidity.Furthermore,we discuss the issues related to ARP packet and Jumbo frame,and actually test their impact on our system.

Key words: gigabit Ethernet;UDP/IP protocol stack;DDR2 SDRAM;Jumbo frame
