ABSTRACT:
A high speed adder suitable for incorporation into electronic digital processing circuits includes at least one first independent adder assuming a carry in of zero (0); at least one second independent adder assuming a carry in of one (1); carry prediction logic circuitry for producing carries for the first and second independent adders, which carry prediction logic circuitry is operable simultaneously with the first and second independent adders; and a final mux for producing a correct result based upon outputs received from the first and second independent adders and the carry prediction logic circuitry.
