Just need answer for part b. Answer for part a. is known.

1.Answer the following questions about the following two machines

Machine A: 2GHz frequency, 1.5 Cycles per instruction

Machine B: 1.5 GHz frequency, 2.0 Cycles per instruction

a. Suppose Machines A and B use different ISAs and that the instruction count for each machine is not the same. Which machine has better execution time and how much faster is it?

Machine As instruction count is 10G instructions

Machine Bs instruction count is 5G instructions

Answer: B is 1.125 times faster than A.

b. Is it really possible for ISA to affect the instruction count so dramatically? If so, how?
