A fast divider implementation based on the Newton-Raphson method using parallel computation units

Abstract

In this paper, a special divide hardware unit based on the Newton-Raphson iteration method is proposed. To compute the reciprocal fast in division process, it utilizes fourth order Newton-Raphson reciprocal approximations. By using fast and efficient parallel computation units the divider achives the computations. These units compute the second, third and fourth order Newton Raphson terms more faster than the standart technique using direct multipliers.
