Paper Abstract

High-speed elementary function generation is crucial to the performance of many DSP applications. This paper presents a new Composite Polynomial Method for generating elementary functions using second-order interpolation. The composite polynomial takes the average of two second-degree polynomials with an overlapping subinterval, and features the minimum approximation error the overlapping subinterval. Its implementation uses small memory with minimal additional computational circuitry and represents a competitive design with respect to existing designs.
