This appears to be from 2004, and it uses PCI (a now outdated and unused bus - everything is PCI Express now, which is completely different). However, if you’re interested in the low-level details of ethernet interfaces, or how an FPGA design goes from concept to completion, this is very informative.

It’s also worth noting - more to the point of the paper - that there are companies offering FPGA-based gigabit NICs right now. You can define custom packet-handling logic in silicon. Pretty neat.

To be totally fair, the PCI interface is delegated to a sub-FGPA on this design, so it probably wouldn't be that big of a schlep to convert.

That existed then too. This paper is about an AVNet board.
