A high-speed NMOS microprocessor has a 64-bit address bus and performs a memory access every 50 ns. Assume that all address bits change during every memory access, and that each bus line represents a load of 10 pF.
(a) How much power is being dissipated by the circuits that are driving these signals if the power supply is 2.5 V?
(b) 3.3 V?
