| 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. It leads to fast and small architectures for digital-signal or image processing applications. | ||
