Abstract [en]

In this work a novel approach for approximating elementary functions is presented. By rewriting the function as a sum of weighted bit-products an efficient implementation is obtained. For most functions a majority of the bit-products can be neglected and still obtain good accuracy. The method is suitable for high-speed implementation of fixed-point functions.
