Abstract: In the prevalence of DSP applications the weighted operations are the multiplication and accumulation. Multiplier-Accumulator (MAC) unit that consumes low power is always a means to accomplish a high concert digital signal processing system. Finite impulse response (FIR) filters are widely used in various DSP applications where signal were present with noise (e.g. data converters). Uptill many proficient techniques have been introduced for the design of low snag bit-parallel multiple constant multiplications (MCM) process which reduces the intricacy of many digital signal processing systems. On the other hand, digit-serial adder architectures present remarkable n-bit designs which process dynamic size data, since digit-serial operators hold less area and power. The purpose of this work is to design and implementation of low power optimized digital Finite impulse response (FIR) filter architecture using VLSI technique. We design and analyze 1] Direct form 2] Transpose form 3] Transpose using MCM 4] Transpose using digit serial adder 5] Transpose using MCM and digit serial adder. Experimental results shows the efficiency of the various architectures and we found best performance results of Transpose using MCM and digit serial adder design in terms of area and power. To execute this work the design is verified using Active-HDL with MATLAB and synthesis [45nm] using Synopsys.
