摘　　要：随着以太网接口速率与流量的不断增长,实现对高速网络数据流实时、高效采集是网络安全和流量监控中的重要课题。设计了一块基于PCI Express总线的高速数据采集卡,以Xilinx FPGA芯片为硬件载体,实现了4路万兆以太网数据接入,并使用DMA机制通过PCI Express总线将数据传输到上位机。As the increasing of Ethernet interface rate and data traffic, real-time and efficient acquisition of high-speed network data flow is an important subject in the area of network monitoring and security. In this thesis, a high-speed data acquisition card based on PCI Express bus is designed and implemented on Xilinx FPGA chip. The access of 4-port 10 Gigabit Ethernet data, transmission via PCI Express bus to host computer using DMA mechanism are achieved.
