Muralidhar Journal on Electronics Engineering 2249 – 0760 5 3 1 10 Digital Signal Processing (DSP), FIR filter, Field Programmable Gate Array (FPGA), High Speed, Look-up Table FIR filters are basic building blocks in Digital Signal Processing applications, require computationally efficient multiply and accumulate operations so the blocks with the desired characteristics have to be chosen carefully. The multiplier is generally slow and occupies large area, the adder also contributes to long delay when the length of the addition is more. Improving the speed results mostly in large areas, usually they conflict with each other. The signal processing applications consume considerable amount of energy. Hence there is a need for low power, high speed, low area circuits for Digital Signal Processing applications. The aim of this paper is to implement a low power, high speed, area efficient FIR filter. Multiply and Accumulate technique is used for multiplier design and the addition and accumulation operations are performed by Parallel Prefix Adders. Some of the available Parallel Prefix Adder architectures and the hybrid architecture of Parallel prefix adder is used here. The implementation is done for 4-tap FIR filter using Xilinx 14.5 version, with the targeted device of Spartan3E FPGA. The experimental results show that the implemented FIR filter using hybrid parallel prefix adder is efficient in area, consume low power and has high speed compared to existing parallel prefix adder models.
