a. Explain the power trend equation. If a new system has 14.3% less capacitive load and uses only 81.3% of the voltage and frequency of the old system, what percentage of power utilization can be reduced in the new system compared to the old system? b. Suppose a multiplication operation takes 128 seconds in total and among that, 19.5% are serial operations and the rest are parallel operations. If you want to improve the performance by 2.78 times, what improvement do you need to include in the system's parallel operation? C. Define response time and throughput.
