From the dawn of the VLSI based approach for the digital signal processing at most research is centered upon the digital filters and their designing, as filters are the circuit elements which are mainly used in signal processing where among these digital filters the group of filters that have finite duration of impulse response are called FIR (finite impulse response) filters and are having the preference over other groups of filters in the classification as their linearity and standard signal processing characteristics are conducive for implementing in microprocessors and DSP's (digital signal processor). As the ever-changing reforms in technology take place, a system with reconfigurable design has to be provided in order to cope up with the transitions in the research timeline and since there have been many years of ongoing research in the branch of FIR filters with reconfigurable design an analysis of this research is presented by studying the design approach and proposed architectures by various researchers from the last 20 years.
