Abstract: Embodiments include a method of adding first and second binary numbers having C bits and divided into D words to provide a third binary number in E successive adding operations, C, D and E being plural positive integers, the method comprising: a first group of D adding operations adding together respective words of the first and second binary numbers to provide D sum and carry outputs ranging from a least significant to a most significant sum and carry output; one or more subsequent groups of adding operations adding together sum and carry outputs from an immediately preceding group of adding operations, a final group of the one or more subsequent groups resulting in the third binary number consisting of the sum outputs from the final group and a carry from the most significant carry output of the final group, wherein E is less than D.
