An Efficient Hardware Implementation for a Reciprocal Unit

Combination of initial approximation through a table look-up and Newton-Raphson iteration is an effective way to compute reciprocal, which may replace the division op-eration. This paper presents the design and implementation of reciprocal unit, which ...

A fast iterative scheme based on the Newton method is described for finding the reciprocal of a finite segment p-adic numbers (Hensel code). The rate of generation of the reciprocal digits per step can be made quadratic or higher order by a proper ...

Reciprocals and reciprocal square roots are used in several digital signal processing, multimedia, and scientific computing applications. This paper presents high-speed methods for computing reciprocals and reciprocal square roots. These methods use a ...
