Or give me some google keywords? Is there a link with the pentium bug?

- jhallenworld 8y agoI like the small number case: they use a very old logic minimization program to generate the equations for it: https://en.wikipedia.org/wiki/Espresso_heuristic_logic_minimizer https://en.wikipedia.org/wiki/Espresso_heuristic_logic_minim... Otherwise it's taking 32 cycles to do the division. There is a count for this.
