I guess this is one of those cases where you just need to get your hands dirty to really understand it.

I guess this is one of those cases where you just need to get your hands dirty to really understand it. Can you do reasonably efficient [arbitrary size] fixed point arithmetic on your hardware? Do you have 64-bit add with carry and 64-bit multiply with 128 bit results? I'm interested in 64.64 and 128.128. Needed operations are add, sub and multiply. I think compute grids like these could very well be an important part of computing in the future, maybe even the most important part. Ever since when I first saw an article about transputer. Grids or VLIWs, sadly software is always the pain point. I wish you luck, please get this working and right.
