Q3. Figure 1.19 shows the execution time and SPECRatio of 12 SPEC2006 integer benchmarks for the AMD A10 and Intel Xeon E5-2690. a. If the weights of applications perlbench, bzip2, mcf, and hmmer are 0.2,0.4,0.3, and 0.1, respectively. What's the weighted arithmetic mean of execution time on each processor? What's the speedup of Intel Xeon E5-2690 over AMD A10? b. Using AMD A10 as the reference machine, what's the normalized execution time of each application (perlbench, bzip2, mcf, and hmmer ) on these two processors? What's the geometric mean of normalized execution time on each processor? What's the speedup of Intel Xeon E5-2690 over AMD A10 using the normalized execution time
