摘要

The invention concerns a digital circuit for calculating the logarithm of a number and a corresponding method of operation a computer system. The calculation is based on the selection of a set of factors fi to obtain intermediate values IK. The logarithms of the selected factors fi are stored in a look-up table and are used to calculate the logarithm of the number by a simple summation. <IMAGE>
