Question:
Consider a processor that runs at 5 GHz and 1 Volt. When running a given CPU-bound program, the processor consumes 100 W, of which 20 W is leakage. The program takes 5 seconds to execute. The processor is capable of running at different voltages and frequencies. Assume that the processor is capable of executing safely at voltages between 0.8 V to 1.2 V. Voltage and frequency follow a linear relationship (i.e., if voltage doubles, frequency doubles as well. Compute the following values:
(1) The shortest time it would take to execute the program.
(2) The lowest power to execute the program.
(3) The lowest energy to execute the program.
