What if we limit the values for the derivative to 4, 2, 1, 0.5, 0.25, etc.? Then we just store a shift count, and you only need a barrel shifter (or a shift register, but that would make it multiple cycle which is not good), and no multiplier at all. I've looked at the model for a bit, we are talking about the divide at line 720 of render.cpp right? And the input will be a normalised float with 1 bit sign, 8 bits exponent, and 16 bits mantissa?
