What is Design and Implementation of an Error‐Margin Aware Approach for Non‐Uniform Segmentation of Elementary Functions Using Degree‐N Polynomial Approximation about?

Elementary functions are widely integrated in many embedded applications such as speech recognition and signal processing. This paper deals with the issues related to the hardware implementation of those functions. Indeed, a novel efficient Error‐Margin aware Approach for non‐uniform Segmentation of Elementary Functions using degree‐N Polynomial Approximation (EMASEF‐NPA) has been proposed. The bit‐width optimization (BWO) process has been used to obtain a better representation of the approximation polynomial coefficients. The principle of content‐addressable memory (CAM) and Horner's rules have been used in the physical implementation. Functional verification, logical synthesis, and physical implementation were performed using the FPGA platform. The results obtained using EMASEF‐NPA approach show a significant reduction, up to 70%, in the number of segments compared to conventional approaches. The findings of the physical implementation show a considerable decrease in area and delay. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.
