You don't need a boatload of registers to pipeline this function. Just regenerate the intermediate results as needed. You'll need to do about twice the work but with no register files it will be a fraction of the size. Of course, I still don't think it's worth building. Why don't you just sell the stat points directly? On Jul 14, 2004, at 10:58 AM, Jim C.
