Need help designing a Arithmetic Bit Slice Unit

    Need help designing a Arithmetic Bit Slice Unit....

    1. The problem statement, all variables and given/known data
    I need to design a Arithmetic Bit Slice unit built upon a full adder that performs the following operations on two bit A and B and carry in Cin.

    A + B A-B
    A+1 A-1
    B+1 B-1
    B A
    0 1
    Not B Not A

    3. The attempt at a solution

    Ok. The full adder was no problem. I have it built and running correctly. Need helping starting the bit slice unit. Do I need to do a truth table for A and B separately? Example: 00=A, 01=/A, 10=0, 11=1

    And do the same thing for the B side also. Is that a good start?
