Decimal carry-lookahead adder Consider the design of a 15-digit decimal adder for unsigned numbers (width = 60 bits). a. Design the required circuits for carry-generate and carry-propagate assuming binary-coded decimal digits. b. Repeat part a with excess-3 encoding for the decimal digits, where digit value a is represented by the binary encoding of a 3. c. Complete the design of the decimal adder of part b by proposing a carrylookahead circuit and the sum computation circuit. | Numerade
