Consider four different processors P1 P2 P3. and P4 executing the same instruction set. Pihasa 3.0 GHz dodatno CPI of 1.5: P2 has a 25 GHz clock rate and a CP1 of 1.25 P3 has a 4.0 GHz Clock rate and a CPI of 22 PA has 20 clock rate and a CPI of 2.75 . Assume that processor P2 executes a benchmark program in 10 seconds. Using paper and pencil calculate the number of cycles required to execute the program and the number of instructions executed in the program. Choose your answers from the following values: 10*10^9:20*10^9: 18.18 1019: 30*10^9 : 7271049: 10*10^9: 12.5 10 9 - 15 10^9: 32*10^9: 32.5*10^9: 21.5*10^9: 24*10^9 : Cycles (P1)=Blank 1 - No. Instructions (P1)= Blank 2 b. We are trying to reduce the execution time by 25%, but this leads to an increase of 20% in the CPL. What is the new CPI for the processor P2? And if p2executes a 20*10^9 instructions program, what cock rate (in GHz) should we have to get this time reduction? Choose your answers from the following values: 11.8: 7.04: 2.64: 1.5: 2.4: 4.8: 4.0: 3.3: 6.4 : 5.0: 3.5: 4.5: 2.8: 4.6: 8.8: 2.25: 3.0 CPlew (P2)= Blank 3 Clock rate (P2)= Blank 4 GHz Blank 1 Add your answer lank 2 Add your answer ank 3 Add your answer nk 4 Add your
