Abstract

Methods, machines, and systems are provided for very high radix division using narrow data paths. A numerator and denominator are received for a very high radix division calculation. An approximate reciprocal of the denominator is obtained from a data structure. The numerator and denominator are pre-scaled by the reciprocal. The denominator is decomposed to an equivalent expression that results in a number of leading insignificant values. Next, modifying a current remainder by forming a first product and subtracting the equivalent expression iteratively assembles a quotient.
