The NetFPGA is the low-cost reconfigurable hardware platform optimized for high-speed networking. The NetFPGA includes the all fo the logic resources, memory, and Gigabit Ethernet interfaces necessary to build a complete switch, router, and/or security device. Because the entire datapath is implemented in hardware, the system can support back-to-back packets at full Gigabit line rates and has a processing latency measured in only a few clock cycles.

  • Field Programmable Gate Array (FPGA) Logic
    • Xilinx Virtex-II Pro 50
    • 53,136 logic cells
    • 4,176 Kbit block RAM
    • up to 738 Kbit distributed RAM
    • 2 x PowerPC cores
    • Fully programmable by the user
  • Gigabit Ethernet networking ports
    • Connector block on left of PCB interfaces to 4 external RJ45 plugs
    • Interfaces with standard Cat5E or Cat6 copper network cables using Broadcom PHY
    • Wire-speed processing on all ports at all time using FPGA logic
      • 1 Gbits * 2 (bi-directional) * 4 (ports) = 8 Gbps throughput
  • Static Random Access Memory (SRAM)
    • Suitable for storing forwarding table data
