Consider two different machines, with two different instruction sets, both of which have the same clock rate of 200 MHz (M = 106). The following measurements are recorded on the two machines running a given set of benchmark programs:

Instruction Type	Instruction Count (in million)	Cycles Per Instruction Execution
Machine A:
Arithmetic and logic	8	1
Load and store	4	3
Branch	2	4
Others	4	3
Machine B:
Arithmetic and logic	10	1
Load and store	8	2
Branch	2	4
Others	4	3

a. Determine the effective CPI for each machine. Reduce your answer to a final value.

b. Determine the MIPS for each machine. Reduce your answer to a final value.
