Self-Checking Carry-Select Adder Design Based on Two-Rail Encoding

Carry-select adders are one of the faster types of adders. This paper proposes a scheme that encodes the sum bits using two-rail codes; the encoded sum bits are then checked by self-checking checkers. The multiplexers used in the adder are also totally self-checking. The scheme is illustrated with t...
