Exercise 2. [30 Marks The following tables summarizes the instructions present in some program (Table 1) as well as two different processors (Table 2) OperationFreguency OperationProcessor 1 Processor 2 ALU Load Store ranch 1500 800 600 100 ALU Load Store Branch 6 Table 1: Program Instructions Table 2: Processor Instruction Cycles (a) [5 Marks] Calculate the ideal CPI of this program running on Processor 1 (b) [5 Marks Calculate the ideal CPI of this program running on Processor 2 (c) [5 Marks] Assuming that Processor 1 operates at 2.5 GHz and Processor 2 operates at 2.7 GHz calculate the CPU time for the program when run on each processor. On which processor is the program faster? (d) [5 Marks In terms of the three factors calculating CPU time (instruction count, CPI, clock frequency) explain why the processor from part (c) is the faster one. How could a programmer change the program described in Table 1 so that it would run faster on the other processor? (e) [10 Marks] Calculate the CPU time of the program described in Table 1 running on Processor 1 (at 2.5 GHz) when also considering memory stall cycles (and thus have CPU time calculated using CPIstall). Assume this processor has one level of cache, an instruction miss rate of 2%, a data miss rate of 5% and a miss penalty of 100 cycles
