Design and Implementation of FIR Filters Using Verilog

Abstract: Finite Impulse Response (FIR) filters play a crucial role in digital signal processing applications, demanding high-speed and power-efficient arithmetic operations. The design and implementation of a 7-tap Finite Impulse Response (FIR) filter using Verilog is a crucial task in digital signal processing (DSP) applications. In this project, a high-performance, area-efficient, and fast 7-tap FIR filter is designed utilizing Kogge-Stone Adder (KSA) for the addition operations within the filter structure. The Kogge-Stone Adder, known for its parallel prefix structure and logarithmic delay, significantly improves the speed of the filter compared to conventional ripple-carry adders. The development process is carried out using Xilinx ISE 14.7 software, installed within a VirtualBox environment for compatibility and ease of access. The project covers the complete flow from RTL design, functional simulation, synthesis, and timing analysis.
