System and method for optimized reciprocal operations |
摘要 |
A method and apparatus for calculating a reciprocal of an integer using a modified Newton Raphson method using one's complements instead of two's complements. The method includes determining a required precision; determining a number of iterations T responsive to the required precision; normalizing N into d; obtaining initial approximation of 1/d=R[0]; refining reciprocal approximation by the modified Newton Raphson operation using ones complements; truncating final iteration result R[T] responsive to the required precision; denormalizing R[T]; and outputting the reciprocal R.
