4.39.4 [20] <4.6, 4.14> It is often possible to sacrifice some speed in a circuit in order to reduce its energy consumption. Assume that we can reduce energy consumption by a factor of X (new energy is 1/X times the old energy) when we increase the latency by a factor of X (new latency is X times the old latency). Using this tradeoff, we can adjust latencies of pipeline stages to minimize energy consumption without sacrificing any performance. Repeat 4.39.2 for this adjusted processor. | |
