Abstract
A method for detecting overflow in an add operation on first and second decoded bit-vectors is provided, the method including generating a one-ahead vector using the first decoded bit-vector. The method also includes selecting an overflow bit from bits of the one-ahead vector using the second decoded bit-vector.
