Design of Low Area and High Speed Parallel FIR Digital Filter using Fast FIR Algorithm

Abstract

Finite Impulse Response (FIR) is thought to be one amongst the most important operations in digital signal processing. Parallel FIR filter has various applications in video compression and equalizers. Implementation of traditional parallel FIR filter offers high speed at the expense of increased hardware by the block size. This huge hardware penalty can't be tolerated in many design situation. So, it's necessary to style parallel FIR filter structures that is implemented with low area than traditional block FIR filtering structures. This paper addresses the design of higher order Parallel FIR filters using small sized filters using FFA algorithm. The Parallel Fast FIR Algorithm specially targets within the sharing of filter coefficients .The Parallel Fast FIR algorithm gives the output with delay of 13.0825 ns which is 47 you quicker than Parallel FIR Algorithm which produces the output with delay of 17.9675 ns. The Parallel Fast FIR Algorithm has been implemented in Four tap , Eight tap FIR filter and sixteen tap FIR filter yet in Parallel FIR Algorithm and Traditional FIR algorithm.
