Abstract
Optimizing the power used in an integrated circuit. A circuit-level transformation/permutation reduces the power consumed by multipliers or other components in integrated circuits. Signals that toggle frequently are assigned to lower power multiplier ports or the number of times a signal changes value is minimized. Large width signals are assigned to the low power port. Large multipliers are divided up and optimized as above. Pipelined multipliers are used with registers so that signals change together.
