Memory-Based FIR Digital Filter Using Modified OMS-LUT Design

摘要

In this paper, a modified optimization of look-up table (LUT) used in memory-based multipliers is used for the implementation of FIR digital filter. Modified odd multiple scheme (OMS) is being proposed for the implementation of FIR filter, and the comparison results have been carried out between the conventional multiplier-based FIR filter design and the modified OMS multiplier-based FIR filter design in which we see that the modified OMS multiplier-based FIR filter requires less memory in comparison to conventional multiplier-based FIR filter. The filter structure is simulated using Verilog code and implemented in Xilinx Virtex device, and its performance characteristics are discussed.
