5. Figure 1 below presents the performance of selected processors and a fictional one\ (Processor X). For each system, two benchmarks were run. One benchmark exercises the\ memory hierarchy, giving an indication of the speed of the memory for that system. The\ other benchmark, Dhrystone, is a CPU-intensive benchmark that does not exercise the\ memory system. Both benchmarks are displayed in order to distill the effects that\ different design decisions have on memory and CPU performance.\ Chip # of\ cores\ Clock\ Frequency\ (MHz)\ Memory\ Performance\ Dhrystone\ Performance\ Pentium D 820 2 3,000 3,228 20,718\ Athlon 64 X2\ 3800+ 2 3,200 2,941 15,129\ Pentium 4 570 1 2,800 3,501 11,210\ Processor X 1 3,000 2,100 2,500\ Figure 1. Performance of several processors on two benchmarks\ a. Create a table similar to that shown in Figure 1, except express the results as\ normalized to the best performing processor for each benchmark. (For both\ benchmarks, a larger number indicates better performance.)\ b. Imagine that your company is trying to decide between Processor X and the Pentium\ 4 570 processor. You know that your application will spend 40% of its time on\ memory-centric computations, and 60% of its time on processor-centric\ computations.\ i. For Processor X and the Pentium 4 570, calculate the weighted performance\ of the memory and CPU benchmarks combined.\ ii. How much performance improvement (or loss) do you anticipate if you move\ from using Processor X to a Pentium 4 570 for the assumed workload?
