1.12

The following table shows results for SPEC2006 benchmark programs running on an AMD Barcelona.

a) perl: Intr. count 10^9= 2118, Execution time (seconds)= 500, Reference time (seconds)= 9770

b) mcf: Intr. count 10^9= 336, Execution time (seconds)= 1200, Reference time (seconds)= 9120

1.12.1 [5] <1.7> Find the CPI if the clock cycle time is 0.333 ns.

The following table shows data for further benchmarks.

a) sjeng: CPI= 0.96, Clock rate= 4 GHz, SPECratio= 14.5

b) omnetpp: CPI= 2.94, Clock rate= 4 GHz, SPECratio= 9.1

1.12.4 [5] <1.7> Find the increase in CPU time if the number of instruction of the benchmark is increased by 10% without affecting the CPI.

1.12.5 [5] <1.7> Find the increase in CPU time if the number of instruction of the benchmark is increased by 10% and the CPI is increased by 5%.
