First step: enumerate _all_ the problems that have to be solved... both the easy ones _and_ the hard ones. I have tried to explain some difficulties. But you seem to want to take this as some sort of criticism of the idea. Remember that I have written several computer chess programs. Doing it in a high-level language is _not_ a simple project. Doing it in hardware is a much more complex problem. And is going to require some solutions to problems that don't exist in a software-type program. I studied the Belle design carefully when Ken described it in a couple of publications. What he did was complex. Hsu improved Ken's design and reduced it to a single chip. And I have seen what he did to make that work. It is non-trivial. I've tried to explain some severe problems that FPGAs are going to have, when you set about to design a chess engine that fits on a single chip. The problems are _enormous_. But _not_ impossible, possibly, although a single-chip FPGA engine is definitely impossible IMHO. But perhaps a single-board PCI-type card might hold a couple of FPGA-based chess engines with the necessary support hardware to provide registers, memory, stacks, etc... It's an interesting problem to discuss. But if you tend to take every problem that is pointed out as a personal attack, it isn't going very far. Folks have pointed out _many_ flaws in Crafty's code over the years. I try to fix them. The same approach has to be taken here, or this is not worth discussing... IE if I am going to build a robot to perform surgery, I am _definitely_ going to listen to a MD that explains certain very tedius things that must be done right, even if some of them seem nearly impossible to implement. I want to know about the big hurdles _early_. Not after a couple of years worth of work... just my $.02...
