"Trivia... Ripple-adders are kind-of a pig when it comes to programmable
device resources. Each pass (bit) takes a macrocell, so a 12 bit adder
eats ~38% of a 32 macrocell PLD! Still though-- a comparitor, an adder, a
subtractor, and some registers should cover what we need for Bresenham's in
hardware."
..do it serially! you've got the clock speed
I talked to Jim, and he's trying to find the data.
