The block diagram and the logic symbol of a 4-bit parallel adder are shown below. Using the logic symbol on the right, show how to use two such adders in order to expand to handle 8-bit addition. Draw the diagram of the 8-bit adder and demonstrate its operation by showing the addition of A: 00110011 and B: 00001111. Show all numbers on the diagram. Σ A, B Binary number A 4-bit sum Co A N C. AB C AN C Binary number 8 (MSB) (LSB) Ca Ca Cot Input Output carry carry (a) Block diagram (b) Logic symbol
