Problem 4 [4 pts]
A compiler designer is trying to decide between two code sequences for a particular machine. Based on the
hardware implementation, there are three different classes of instructions: Class A, Class B, and Class C,
and they require one, two, and three cycles (respectively).
The first code sequence has 5 instructions: 2 of A, 1 of B, and 2 of C
The second sequence has 6 instructions: 4 of A, 1 of B, and 1 of C.
1. Which sequence will be faster? How much?
2. What is the CPI for each sequence?

Problem 5 [4 pts]
Design a single-cycle data path that can do the following:
Given: Registers A, B and C
Compute:
if Function = 0
then compute (A + B) * C
else if Function = 1
then compute (A + C) / B
else if Function = 2
then compute (B - C) / A
Your circuit should include the following:
Registers A, B and C, (Assume they already have the right values loaded),
1 adder/ subtractor, 1 multiplier block, 1 divider block,
Any multiplexers you may need.
