Hardware Operator for Simultaneous Sine and Cosine Evaluation

Arnaud Tisserand

Abstract

This work deals with hardware evaluation of the sine and cosine functions for the same argument simultaneously. The proposed method uses trigonometric identities, small lookup tables and low-degree polynomial approximations with very sparse coefficients. Most of the multiplications are replaced by a small number of additions or subtractions, this leads to small and fast circuits.
