Abstract: “Addition play important role in our day to day life the saying goes on “if you count you can control” mathematical operation are mostly used in arithmetic application, it is a basic operation for any digital electronics system, adder is a combinational circuit.Fast adder is used in digital electronics, to increase the speed by reducing the amount of time required to determine carry bit. This project deals with high data rate implementation of adder on field programmable gate array (FPGA).Different adder architecture is compare on the basis of their clock speeds & the resource utilization.”

Keywords: layout in terms of area, speed of operation, reduce propagation delay, Carry select adder, ripple carry adder
