Design of Intelligentized Network Card based on FPGA

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。

Abstract:

In order to design a Intelligentized Network Card based on FPGA and SOC,that composed of the PowerPC440 Processor, the Interface 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, compilation and simulation. The Intelligentized Network Card based on SOC and TEMAC has been implemented in the Virtex-5 of XILINX, The Network Card has the advantages of flexibility,configurability,opening,extending,smallness and low consuming.
