You are designing a system for a real$-$time application in which specific deadlines must

be met. Finishing the computation faster gains nothing. You find that your system can

execute the necessary code, in the worst case, twice as fast as necessary.

a$)$ How much energy do you save if you execute at the current speed and turn off

the system when the computation is complete?

b$)$ How much energy do you save if you set the voltage and frequency to be half

as much?
