摘　　要：在高速信息系统中,FPGA能高速地处理数据,千兆以太网能高速地向远程传输数据,可是FPGA与千兆以太网的连接却存在着很多问题。为使FPGA能直接接入千兆以太网,以便进行高速数据传输,本文以Xilinx公司的Virtex-5FX30T为例,采用SOPC接术,使用FP-GA系统无缝连接千兆以太网,取得了高速的传输速率。此外,该设计的数据接口灵活可变,能满足多种应用需求。In high speed signal processing system, data can be processed by FPGA rapidly and be transmitted through gigabit Ethernet quickly, but the big problem is how to connect FPGA to gigabit Ether- net. The paper takes Xilinx Virtex-5 FX30T for example, and presents an approach for implementing the completed seamless connection between FPGA and gigabit Ethernet using SOPC technology. Experiments demonstrate that high-speed transmission rate is reached. Additionally, the proposed data stream interface is flexible and can thus be applied in many situations.
