ABSTRACT:
A method is disclosed for accomplishing modulo 2.sup.2n -1 addition with apparatus requiring adders that may be all standard binary adders. The method requires summing binary input signals a and b to produce a first sum signal in which the n+2 more significant bits thereof represent the integer part of a+b taken modulo 2.sup.2n. These n+2 more significant binary bits are subtracted from a 2n bit shifted product representation thereof for producing a first difference signal. This difference signal is subtracted from the first sum signal to produce a binary signal R. When R is greater than or equal to the constant (2.sup.2n -1), this constant is subtracted from the signal R for producing a binary signal that is the first sum signal a+b taken modulo 2.sup.2n -1 .
