Latency, Throughput, Speedup, and The Iron CPU Performance Law (a) Consider three different CPUs, P1, P2, and P3, implementing the same ISA and each executing a program P. The performance data for each CPU is given in the table below. For questions (i)-(iii), ignore the instruction count and program latency columns in the table. i. Which CPU has the highest performance expressed in instructions per second? ii. Suppose the CPUs each execute program P in 10 seconds. Compute the number of clock cycles each CPU takes to execute program P and the dynamic instruction count executed by each CPU. iii. The goal is to reduce the program's latency by 30% but this leads to an increase of 20% in the CPI for each CPU when executing program P. What clock frequency should each CPU have to achieve this latency reduction
