Abstract
An alternative approximate processing method which dynamically adjusts the precision of the canonic signed digit (CSD) coefficients is proposed. This proposed method employs a two-stage search for finding approximated values of CSD coefficients. Experimental results show that the number of additions is reduced to 29.4%, 11.8%, and 3.9% for each approximation level
