Your Company's internal studies show that a single-core system is sufficient for the demand on your processing power; however, you are exploring whether you could save power by using two cores. Assume your application is 80% parallelizable. By how much could you decrease the frequency and get the same performance? Assume that the voltage may be decreased linearly with the frequency, how much dynamic power would the dual-core system require as compared to the single-core system? Assume the voltage may not decrease below 25% of the original voltage. This voltage is referred to as the voltage floor, and any voltage lower than that will lose the state. What percent of parallelization gives you a voltage at the voltage floor? How much dynamic power would the dual-core system require as compared to the single-core system when taking into account the voltage floor?
