Abstract
A full-adder post processor performs modulo arithmetic. The full-adder post processor is a hardware implementation able to calculate A mod N, (A+B) mod N and (A−B) mod N. The processor includes a full adder able to add the operands A and B while modulo reduction is accomplished in the processor by successively subtracting the largest possible multiple of the modulus N obtainable by bit shifting prior to subtraction.
