摘要
为了提高通信系统的数据吞吐量,增加系统集成度,在IEEE 802.3ae标准的基础上,对万兆以太网技术进行了研究并实现。万兆以太网技术是基于FPGA实现的,FPGA完成的主要工作包括:完成与上层软件的指令和数据交互、数据的组帧/解帧、与物理层的接口管理等。物理层发送端主要完成数据对齐、变速并加扰、并串转换等工作,将串行数据发送给光电转换模块,接收端正好相反。经过万兆以太网标准仪器测试,传输速率达到了10 Gb/s,大大提高了系统间数据传输的速度和效率,简化了系统结构。
To improve the data throughout and system integration of communication systems, the paper proposes a method of implementing 10 Gb Ethernet technology based on IEEE 802.3ae standard. The implementation of the 10 Gb Ethernet technology is based on FPGA,which performs the instruction and data interaction with the software,the frame encoding and decoding of data and the management of physical interface. The physical layer transmitter mainly performs data alignment, rate change, scrambling and parallel-to serial conversion, and finally transmits the serial data to the O-E conversion module ;while the receiver performs the reverse process. The transmission rate of the 10 Gb Ethernet technology reaches 10 Gb/s,so it greatly improves the transmission rate and efficiency between systems and simplifies the system structure.
