摘　　要：随着计算机网络接入技术千兆以太网在各个科技领域的广泛应用,愈来愈多的研究倾向于设计高速以太网接口电路,以实现当局部设备接入网络时,数据能够以更高速率、高效率地进行传输。文章根据局域网中两个工程机之间需要发送数据包的需求,设计了包含FPGA板卡在内的利用以太网接口互传数据传输系统的实现方案。同时还设计了基于Xillinx公司IP核的MAC层控制模块,该模块不仅可以完成标准千兆以太网帧的数据传输,还能够通过配置模块来完成数据打包与解包的工作。由测试实验可知,文中设计的高速以太网接口电路能有效的传输高清视频数据流,并在传输过程中未出现视频流卡顿和数据包丢失的现象,因此有较高的工程应用价值。With the application of Gigabit Ethernet in various fields of computer network access technology,more and more research is inclined to design high speed Ethernet interface circuit,in order to achieve high speed and high efficiency data transmission when local devices are connected to the network.According to the need of sending data packets between two engineering machines in LAN,this paper designs the implementation scheme of data transmission system between engineering machines by Ethernet interface including FPGA board card.A MAC layer control module based on MAC IP core of Xillinx is designed,which can complete the transmission of standard Gigabit Ethernet frame data.Data packaging and unpackaging can be realized by configuring the module.Finally,through the test experiment of transmitting high-definition video stream data,it can be seen that the high-speed Ethernet interface circuit designed in this paper can effectively transmit high-definition video data stream,and there is no video stream deadlock and packet loss phenomenon in the transmission process,which has relatively high engineering application value.
