Question: How much energy is spent to execute an ADD instruction in a single-cycle design and in the 5-stage pipelined design? This exercise explores energy efficiency

How much energy is spent to execute an ADD instruction in a single-cycle design and in the 5-stage pipelined design?

This exercise explores energy efficiency and its relationship with performance. Problems in this exercise assume the following energy consumption for activity in Instruction memory, Registers, and Data memory. You can assume that the other components of the datapath spend a negligible amount of energy. a. b. I-Mem 140pJ 70pJ 1 Register Read 70pJ 40pJ Register Write 60pJ 40pJ D-Mem Read 140pJ 90pJ D-Mem Write

a. b. I-Mem 140pJ 70pJ 1 Register Read 70pJ 40pJ Register Write 60pJ 40pJ D-Mem Read 140pJ 90pJ D-Mem Write 120pJ 100pJ
