Homework Help: Full Adder Circuit help

  1. Jan 11, 2012 #1
    Heres my truth table

    Code (Text):

    A|B|Cin|Sum|Cout
    0 0 0 0 0
    0 0 1 1 0
    0 1 0 1 0
    0 1 1 0 1
    1 0 0 1 0
    1 0 1 0 1
    1 1 0 0 1
    1 1 1 1 1
     
    Here's my two equations from the K-maps

    Sum = A+B+CIn
    Cout = A.B+CIn(A+B)

    Now what I want to ask is, is there a way the gate count be reduced further by sharing terms between the two output functions?

    Thanks.
