High Speed and Area Efficient Parallel Fir Digital Filter Structures for DSP

Finite impulse response (FIR) digital filters are one of the most widely used fundamental devices performed in DSP systems, ranging from wireless communications to video and image processing. This paper proposes new parallel FIR filter structures, which are benef cost, under the condition that the number of taps is a multiple of 2 or 3. The 5 parallel FIR structures gives low area and high speed compare to existing 4 parallel architecture , exploit the inhere reducing half the number of multipliers in sub filter section at the expense of additional adders in preprocessing and post processing blocks. Exchanging multipliers with adders is advantageous because adders weigh less multipliers in terms of silicon area. Due to reduction of multipliers, will get low area and high speed fir filte
