High-performance Filter Design with Fast Binary Counters and Sorting Network
摘要
This paper demonstrates a new method to filter optimization by leveraging fast saturated binary counters, specifically employing (7, 3) configuration. Digital filters are fundamental components in Digital Signal Processing (DSP) systems, typically comprising delay elements, adders, and multipliers. Among these, adders and multipliers play pivotal roles in FIR filter design. Our primary objective is to enhance FIR filter efficiency by integrating efficient multipliers. To achieve this goal, we begin by designing (7, 3), (15, 4), and (31, 5) counters. These counters serve as essential components for our approach. Subsequently, we assess the performance of these counters, with particular focus on the (7, 3) configuration. Applying the (7, 3) counter to multiplier design, we observe significant improvements in Finite Impulse Response (FIR) filter performance. The FIR filter is designed in Verilog Hardware Description Language (HDL) to validate our approach, and it is simulated using the Xilinx VIVADO tool. Through this process, we demonstrate the efficacy of our proposed method in enhancing filter efficiency and overall signal processing performance.
