A company is trying to decide between a single-processor system and a dual-processor system. A memory-centric benchmark and a CPU-centric benchmark performance calculations are given in the table below. On average the company applications spend 40% of their time on memory-centric computations, and 60% of their time on processor-centric computations. a) Calculate the weighted execution time of the benchmarks for Processor 1 and Processor 7. b) How much speedup do you anticipate getting if you move from using a Processor 7 to Processor 1 on a CPU-intensive application suite? c) How much speedup do you anticipate getting if you move from using a Processor 6 to Processor 2 on a Memory-intensive application suite? d) At what ratio of memory to CPU computation would the performance of the Processor 7 be equal to Processor 3?
