Abstract
Sum and carry signals are formed representing a product of a first and a second operand. A bias signal is formed having a value determined by a sign of a product of the first and the second operand. An output signal is provided based on an addition of the sum signal, the carry signal, a sign-extended addend, and the bias signal. A portion of the output signal, a saturated minimum value, or a saturated maximum value, is selected as a final result based on the sign of the product and a sign of the output signal.
