Abstract
A method and apparatus for a multi-purpose adder is described. The method includes calculation of an initial sum for each corresponding N-bit portion of a received addend signal and a received augend signal. Generation of an initial carryout signal for each calculated initial sum is then performed. Next, an intermediate sum for each group of M-initial sums according to a respective initial carryout value of each initial sum is then generated. Once generated, an intermediate carryout value for each generated intermediate sum is then calculated. Finally, a final sum is calculated from the intermediate sums generated according to a respective intermediate carryout of each intermediate sum.
