you're thinking of address bits - going from 21-bits to 22-bits of microcode increases the area by 1/21th

- marcosdumay 6y agoOh, that's right. It increases linearly with the size of the CPU instruction words in a dimension and the size of the microcode instruction words on the other dimension. The entire exponential addressing space is not used, since there is an overall structure to both instruction sets.
