1. The first two full adders would add the first two bits together. 2. Serial binary addition is done by a flip-flop and a full adder . 3. The delay of this adder will be four full adder delays, plus three MUX delays. 4. And the final set of full adders would assume that C _ 1 is a logical 1. 5. Thus, a truth table of eight rows would be needed to describe a full adder 's logic: 6. Connections between multiple half-adders may then be used to form full adders in accordance with conventional arithmetic architectures. 7. The second set of 2 full adders would add the last two bits assuming C _ 1 is a logical 0. 8. A "'full adder "'adds binary numbers and accounts for values carried in as well as out. 9. It is possible to create a logical circuit using multiple full adders to add " N "-bit numbers. 10. A typical cell consists of a 4-input LUT, a full adder ( FA ) and a D-type mux.
