[Hardware] The market of ASICs (One GigaKey / Second?)

[Dan Oetting]

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?
