NetFPGA (www.netfpga.org) is a platform for developing 1Gbps or 10Gbps wire-speed layer 2 and 3 switching in reprogrammable hardware, using Xilinx Field Programmable Gate Arrays (FPGAs). NetFPGA is developed at Stanford University and enjoys primary support on Linux hosts. The codebase is open source.

In developing a low-power network switch for our Power-over-Ethernet low-cost SoC cluster, we develop the USB2 interface and switching firmware using NetFPGA as a development platform. A small adaptor board has been developed that connects to the debug connector of the NetFPGA card and allows dual USB2 network interfaces for small low-power System-on-a-Chip devices such as NVidia Tegra 2/3, TI OMAP and others.

This presentation will discuss the development of the NetFPGA USB 2 interface using a conglomeration of open-source and freeware tools, all hosted on Linux development platforms.
