The main requirements for filters used in real-time seismic warning systems are low complexity, high speed, and reconfigurability. To achieve these objectives, a combination of techniques is employed. This includes minimizing logic operators and logic depths within the FIR filter and using a Carry Look Ahead Adder (CLA) to reduce critical path delay (CPD). Additionally, the common subexpression elimination (CSE) technique, based on canonical signed digits (CSD), is commonly utilized to decrease hardware complexity. The proposed design of an efficient FIR filter incorporates the techniques. This results in several advantages, including superior performance in terms of area, power, and delay. The implementation of this architecture is done using Verilog, and the results obtained are analyzed through simulation utilizing Xilinx Vivado 2019.1 and Cadence 45nm technology. The architecture proposed yields a 3%,70%, and 83% reduction in CPD, Number of LUTs, and SDP over state of art CSE-based architecture
