High Speed Low Area DA Based FIR Filter Using EGDI Adder

In this paper we proposed a novel enhanced gate diffusion (EGDI) adder is designed and implemented in Distributed Arithmetic (DA) based Finite Impulse Response (FIR) filter. Generally multipliers, adders shift accumulators are the basic blocks present FIR filters. The hardware architecture of multipliers very high. To get rid this, multiplier less needed So place key role filters which will occupy area increase speed. reduce further DA using increases operation speed filter at same time be decreased. design synthesized Synapsis compiler tool. area, power delay product, frequency, product calculated. When observe synthesis results, has 15% high frequency rate when compare with existing design. Also more useful signal processing applications like decision feed-back equalizer.
