The Pentium 4 Prescott processor, released in 2004, had a clock cycle of 250 picoseconds and voltage of 1.25 V. Assume that, on average, it consumed 20 W of static power and 100 W of dynamic power. The Core i5 Ivy Bridge, released in 2012, had a clock cycle of 300 picoseconds and voltage of 0.9 V. Assume that, on average, it consumed 40 W of static power and 50 W of dynamic power. a. For each processor find the average capacitive loads. b. Find the percentage of the total dissipated power comprised by static power and the ratio of static power to dynamic power for each technology. c. If the total dissipated power is to be reduced by 15%, how much should the voltage be reduced to maintain the same leakage current?
