This manuscript refers to the features of a novel finite impulse response (FIR) filter (FIRF) architectural design to denoise electrocardiogram (ECG) signals known as Vedic design-carry look-ahead (VD-CLA) adder. Few research workings dealt with signal denoising with an effective multiplier scheme. The recommended VD-CLA architecture denoises ECG signals as follows: the MATLAB IDE developed part of the VD-CLA treats the input ECG signals tainted by additive white Gaussian noise (AWGN) that can be read from files. The VD-CLA denoising module employed a Verilog realization with the corresponding achieved outputs written in binary text files accessible to MATLAB developed code. The implemented FIRF utilized a low-power multiplier to become faster and more effective than other conventional deployments. Experimental results corroborate the improvements and show that the VD-CLA is suitable for FPGA and embedded designs.
