High Speed Low Area Distributed Arithmetic-fir Filter For Applications Used In Signal Processing

Abstract - In this paper, we present a novel Distributed Arithmetic based Finite Impulse Response filter for signal processing applications. DA based FIR filter will occupy more area and power when filter order is increased. To get rid of this, in the paper, we used offset binary coding (OBC) concept. Instead of using binary inputs we are using OBC values for increasing the speed. By using OBC concept the memory usage will be decreased when compared with the basic DA. The proposed design is implemented in Xilinx tool. The area occupied by the proposed design is half when compared with basic DA. The speed of operation of the proposed design is very high.

Keywords- Distributed Arithmetic, Finite impulse response, signal processing, offset binary coding.
