# Given two numbers a and b, find the sum of a and b. Since the sum can be very large, find the sum modulo 109+7. # You don't need to read input or print anything. Your task is to complete the ...

RippleCarryAdder offers great coverage of traditional addition/subtraction operations; operations modulo 2ᴺ are rather similar, reusing a lot of the same primitives, so it makes sense to add a section ...

Abstract: A new three-operand modulo (2/sup p/ /spl plusmn/ 1) addition is presented, performing a carry-save addition and a two-operand modular addition based on the p-digit radix-two signed-digit ...

Abstract: A theta (1) algorithm for large modulo addition for architectures based on the residue number (RNS) is proposed. The addition is done in a fixed number of stages which does not depend on the ...
