摘　　要：为了实现一种基于FPGA及片上系统(SOC)的智能以太网接口设计,在FPGA内集成了PowerPC440硬核处理器、以太网络接口控制器IP(TEMAC)、DDR2控制器、通用串行接口IP核及定时器等;该设计使用Verilog HDL硬件描述语言,在ISE12.4下的嵌入式集成开发环境XPS下进行IP核定制、系统的集成设计、综合、布局布线,在Model Sim下完成功能、时序仿真,在SDK环境下完成片上系统软件程序的开发;最后在XILINX的Virtex-5系列FPGA器件上实现了具有千兆以太网络接口的智能片上系统,智能网络接口具有可重配置、可扩展性、灵活性、兼容性、功耗低等优点。In order to design a Intelligentized Network Card based on FPGA and SOC, that composed of the PowerPC440 Processor, the Inter- face IP of Network. UART . DDR2 and Timer. Meanwhile, it enhances the precision of synchronous, as well as the anti--jamming ability. So it is ideal for the research and develop of SOC. Verilog hardware description language in the XPS environment of ISE12.4 has been used for its design, com- pilation and simulation. The Intelligentized Network Card based on SOC and TEMAC has been implemented in the Virtex--5 of XILINX, The Net- work Card has the advantages of flexibility, configurability, opening, extending, smallness and low consuming.
