Just question a and b
1) 11 points] Performance evaluation Consider three different processors Pl, P2, and P3 executing the same program consisting of 100 instructions. Pl has a 2 GHz clock rate and a CPI of 2 P2 has a 300 MHz clock rate and a CPI of 3. P3 has a 2 ns cycle time. (a) Calculate the execution time of the program on processors Pl and P2 in seconds and mention which processor is faster [4 points] (b) It was found that the execution of the programme on P3 is two times slower than the execution on P2. Calculate the CPI of P3. [4 points] (c) Find the increase in the execution time of P1 if the number of instructions of the program is increased by 50% (without affecting the CPI). [3 points]
