Abstract [en]

Computations in logarithmic number systems require realizations of four different elementary functions. In this work we utilize a recently proposed approximation method based on weighted sums of bit-products to realize these functions. It is shown that the considered method can be used to efficiently realize the different functions. However, a transformation is proposed to improve the results for functions with logarithmic characteristics.
