摘要
在Xilinx公司的Virtex-5FX70T芯片上设计了一种千兆以太网数据传输方案,在该芯片内嵌的PowerPC处理器上移植了VxWorks操作系统,采用SOPC技术使FPGA无缝连接千兆网卡。实际测试结果表明,通过减少系统开销、优化网络通信性能,本文设计方案的数据传输速率不仅达到系统传输速率要求61.44Mbps的4倍,并且方案的接口灵活可变,能满足其他多种高速网络通信的需求。
Based on Xilinx Virtex-5 FX70T, a gigabit Ethernet data transmission scheme is designed. The PowerPC processor embedded in FX70T is transplanted with VxWorks operating system, and the FPGA and gigahit Ethernet is seamlessey connected using SOPC technology. Practical test results show that the data transmission rate of the design scheme meets the requirements of the system trans mission rate four times that of 61.44 Mbps, and also the interface is flexible so that it can meet the needs of a variety of other high-speed network communications.
