Show how you can use addition blocks (i.e. half-adders and full adders) to add two 8-bit values, A₇A₆A₅A₄A₃A₂A₁A₀ and B₇B₆B₅B₄B₃B₂B₁B₀. When you sketch your design, use the symbols for the addition blocks rather than showing the implementation at a gate level. Label all devices, inputs, and outputs.
