A Novel Architecture of 32 bit Modulo 2n-1 Adder

Abstract

Addition is a operation in which timing consideration is very important in all modern processing units.There is lot of scope for designing efficient and fast adders. Here a new architecture presented for addition of modulo 2ⁿ-1 adder, which allows a highly efficient combinational circuits for modulo 2ⁿ-1 adder implementation in Cryptography and network security.

The modulo architectures are implemented on Nexys 4 DDR, A Vertex-7 field-programmable gate array (FPGA) using Vivado design suit. The results of the new architecture is compared with other proposed architecture, it shows that, the new architectures is better in terms of  Look Up Tables, Power utilization  and Slices utilized .
