ALTBout = 1 if A is less than B, 0 otherwise
AEQBout = 1 if A eqi\uals B, 0 otherwise
AGTBout = 1 if A is greater than B, 0 otherwise
This comparator has three 1-bit inputs ( AEQBin, AGTBin and ALTBin) with the meanings:
ALTBin = 1 if a higher-order compare found the A-bit less than theB-bit
AEQBin = 1 if a higher-order compare found the A-bit equal to the B-bit
AGTBin = 1 if a higher-order compare found the A-bit greater than the
B-bit
Use your 1-bit comparator basic building blocks to design a 4-bit comparator that will compare two 4-bit unsigned integers, be sure to include in your answer the values you will assign to the leftmost AEQBin, ALTBin, and AGTBin inputs.
2. Take an example of two 4-bit numbers and show all the corresponding values on the 4-bit comparator circuit designed in Problem 1. Also show the final result.
3. Give the logic equations for the 1-bit comparator of problem 1.
