As a computing expect, your expertise is required to evaluate the potential performance of two new processors, each implementing a different ISA. The evaluation is based on its performance on a particular benchmark. On the processor implementing ISA A, the best compiled code for this benchmark performs at the rate of 12 IPC. That processor has a 660 MHz clock. On the processor implementing ISA B, the best compiled code for this benchmark performs at the rate of 4 IPC. That processor has a 800 MHz clock. a) What is the performance in MIPS (millions of instruction per sec) of the processor implementing ISA A? b) What is the performance in MIPS (millions of instructions per sec) of the processor implementing ISA B? c) Which is the higher performance processor? d) Explain your answer in c) above
