Title : AREA AND POWER EFFICIENT MULTIPLIERS USING APPROXIMATE COMPRESSORS AND FULL ADDERS FOR DSP APPLICATIONS
S. Revathi1, M.P. Chennaiah2

Abstract :

In this project, a novel approximative full adder is suggested and used in the multiplier's reduction steps. Here, four designs for 8-bit multipliers are looked at for use with the approximate 4-2 compressors that already exist and the approximate full adder that has been suggested. For error-resistant applications, approximate computing can lessen design complexity while enhancing performance and power efficiency. In the majority of multimedia applications, we may learn important things from marginally inaccurate outputs. As a result, we are not required to produce precise results. This short paper shows a unique way to change the logic at the gate level to approximate full adders and take advantage of the loosening of numerical precision. The standard full adder's sum phrase is modified to simplify an area. The efficacy of the proposed solution is developed and simulated using Xilinx Vivado.
