In this paper, the authors describe the design and implementation of highly efficient LUT based circuit for the implementation of FIR filter using distributed arithmetic algorithm. It is a multiplier less FIR filter designed and designed based on distributed arithmetic algorithm. The DA-based technique consists of Look-Up Table (LUT), shift registers and scaling accumulator. Analysis on the performance of filter order with partition on different address length of partial tables are done using Xilinx 12.1 synthesis tool.
