The Finite Impulse Response (FIR) filters are widely used in the satellite link to demodulate signals becauseof its linear phase property and its simple and regular structure compared to Infinite Impulse Response (IIR) filters. Thisis a basic requirement for applications in audio and video filtering. However to achieve the same frequency specification,FIR filters require higher number of taps compared to IIR filters. This paper proposes an architecture which is amodification of existing Distributed Arithmetic (DA) based FIR filter architecture. It helps in reducing the look up tablesize required by a DA based filter. It uses multiplexers and adders to implement the Multiply And Accumulate function(MAC). The proposed architecture helps to reduce area, power and increases the computation speed.
