Power Minimization by Designing Novel Architecture for Multimodal Biometric System

Abstract

Abstract: The reduction of power, area, and delay parameters are increasing as the range of sophistication of applications in VLSI circuit designs. Adders and multipliers play a vital role in VLSI circuit designs to minimize the power consumed by the circuit. The Finite Impulse Response Filter is widely used in Digital Signal Processing Applications, such as speech processing, loudspeaker equalization, echo cancellation, noise cancellation, arithmetic computations and, image-processing applications. In FIR filter, the adders and multipliers are the important components to reduce the power, delay and area. Therefore, this proposed method faced with more constraints: as minimal power as possible. This work proposes a design of low power Finite Impulse Response Filter using Carry Skip Adder.The recent electronics industry uses digital filters for various real time applications. A novel VLSI architecture is designed by using ALU based FIR filters for biometric system. Where in ALU includes adders and multipliers, comparing different adders for there better performance with respect to power and identifying carry skip adder will consume less power compared to other adders. power consumption of overall architecture by including carry skip adder is very less and we can use this same adder for multimodal architecture also.
