Homework Answers
Answer:
The value for
INVA = 0
INC = 0
F0=1
F1=1
ENA=1
ENB=1
As CarryIn is in the initial state so CarryIn =0.
Also, the value of A and B are 0 as the value of ENA and ENB is 1.
The output produced from the following 8 bit ALU is 0.

Assume that the 32-bit ALU
shown above on the right is constructed using the 1- bit ALUs given
above on the left (with proper modifications to support the
set-less-than operation correctly). List all the arithmetic and
logic operations supported by the ALU. For each operation, clearly
explain how the control lines should be set.
