ABSTRACT:
A carry select adder includes an adder for outputting a first sum of values based on a first presumed carry-in of zero and a second sum of the values based on a second presumed carry-in of one. A sum unit produces an actual sum comprising either the first sum or the second sum based on an actual carry-in and simultaneously determines whether the actual sum is all zeros or all ones. The sum unit selects the actual sum and determines whether the actual sum comprises all zeros or ones in the same time period such that there is no significant additional delay associated with the zero/one detection operation.
