The following table shows results for SPEC CPU2006 benchmark programs running on an AMD Barcelona. 5. Name Instruction countExecution time (s) Reference Time (s) bzip2 2389 x 109 1658 x 109 750 700 9650 10490 go Find the CPI for each benchmark if the clock cycle time is 0.333ns. [6 points] Find the SPECratio for each benchmark. [6 points] a. b.Explanation / Answer
a)
CPI = clock rate × CPU time/instr. count
Clock rate = 1/cycle time = 3 GHz
a. CPI (bzip2) = 3 × 10^9 × 750/2389 × 10^9 = 0.94
b. CPI(go)= 3 × 10^9 × 700/1658 × 10^9=1.26
SPECratio = ref. time/execution time.
a. SPECratio (bzip2) = 9650/750 = 12.86
b. SPECratio (go) = 10490/700 = 14.98
