That is very cool. Where would you go from there? It seems if you're already so fast that you can start replying as soon as all the data is received, there isn't much more you can do. Or are there techniques for going beyond that?

You can push the start of the reply earlier than the end of the input with some tricks. Beyond that you're limited by causality.

The bit of the video where he talks about writing the order to the wire and then flubbing the checksum if he doesn't actually want to send the order was nuts. I work in the industry and I had heard of people using FPGAs on switches but not that particular technique. Thanks for posting that.

Damn that causality. High performance would be so much easier if causality wasn't there :p
