Abstract
A method suitable for calculating an expression having the form (A/B) by a processor that features separate sets of floating point units which can operate in parallel for greater speed of execution. The processor issues instructions to determine an approximate reciprocal R of a first variable B. Further instructions are issued to raise a second variable to the power of a third variable K by a first set of arithmetic units of the processor, where the second variable is a function of the approximate reciprocal R . Still further instructions are issued to calculate a polynomial q at a fourth variable delta by a second set of arithmetic units of the processor. The fourth variable delta is also a function of the approximate reciprocal R . Finally, one or more instructions are issued to multiply the calculated polynomial by the second variable, having been raised to the power of the third variable, to yield (A/B) .
