Efficient Design and Implementation of a 4-Tap FIR Filter Using Braun Multiplier and Ripple Carry Adder (RCA)

Finite Impulse Response (FIR) filters are essential components in digital signal processing, with their efficiency significantly influenced by the design of multipliers and adders. This work presents a novel Verilog-based implementation of a 4-tap FIR filter, prioritizing area and power optimization. By utilizing Braun multipliers and Ripple Carry Adders (RCAs), the design achieves a considerable reductions in resource utilization and energy consumption, making it ideal for low-power, compact applications. Detailed simulations and validations conducted using the Xilinx Vivado Design Suite 2024.2 demonstrate the accuracy and reliability of the proposed architecture, with results closely aligning with theoretical predictions. These findings underscore the practicality of the novel design for efficient digital signal processing in embedded systems.
