Question

A high-speed CMOS microprocessor has a 64-bit
address bus and performs a memory access every
2 ns. Assume that all address bits change during
every memory access and that each bus line represents
a load of 25 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) Repeat for
3.3 V.
