The RAM on an FPGA would definitely be useful for creating a computer chess chip. The problem is that you have to put stuff in RAM and take stuff out of RAM. And when you have that restiction, you're basically forcing the FPGA to act like a general-purpose computer. For example, let's say you wanted to find the black king on the chess board. If your board is stored in RAM, you have to take the first element out, check to see if it's the black king, then take the second element out, check to see if it's the black king, etc. If you get to place your memory cells exactly where you want them, then you can check all the squares simultaneously. I think it might be possible to put a chess engine on an FPGA. Definitely not something as sophisticated (or as good) as Deep Blue. But if that isn't your goal, it sounds like a really cool project. -Tom
