We Want To Implement A Full Adder: We'll Call The Inputs A, B, And C And The Outputs S And Cout. As Always, The Adder Is Described By The Following Equations: S(A, B, C) = Sum M(L, 2, 4, 7) Cout(A, B, C) = Sum M(3, 5, 6, 7) To Implement This, All We Have Available Are Two Decoders (As Shown Below - Look At The Enable Bit) And Two OR Gates. Inputs A And B

 

Problem 4: (10 pts) (Ch 5, Prob 9) We want to implement a full adder: we'll call the inputs a, b, and c and the outputs s and cout. As always, the adder is described by the following equations: m(1, 2, 4, 7) s(a, b, c) Cout(a, b, c) = m(3, 5, 6, 7) To implement this, all we have available are two decoders (as shown below - look at the Enable bit) and two OR gates. Inputs a and b are available both uncomplemented and complemented; c is available only uncomplemented. Show a block diagram for this system. Be sure to label all of the inputs to the decoders. 0 A EN A B 0 1 2 3 1 1 X X 0 0 0 0 B 23 2 0 0 0 1 0 0 0 3 0 0 1 0 1 0 0 1 0 0 0 1 0 1 1 0 0 0 001 EN'
