A Survey on Low Area and Low Power Parallel FIR Filter

S. Balasubramaniam, R. Bharathi

Abstract


With the explosive growth of multimedia applications, the demand for high performance and low power digital signal processing is getting higher and higher. Finite impulse response (FIR) filters are one of the most widely used fundamental devices performed in DSP systems. This Paper presents a survey on designing Low Area and Low Power Parallel FIR Filter. By using Fast FIR filtering algorithms (FFA), this parallel FIR structures can Lead to significant hardware savings from the existing FFA Parallel FIR filter. In this paper, Traditional FIR filter structure and FFA based FIR filter structure, Symmetric convolution based FFA FIR filter structure are designed for 2-parallel (2×2) and 3-parallel (3× 3).

Keywords


Digital Signal Processing (DSP), Fast Finite Impulse Response(FIR) Algorithms (FFA), Parallel FIR, Very Large Scale Integration(VLSI) .
