ABSTRACT:
A divider which multiplies both divisor and dividend by a first multiplier generated from the divisor to compute an intermediate divisor and an intermediate quotient, and iterates such computations by the number of times needed, so that the intermediate divisor approaches a predetermined value, and the intermediate quotient approaches the quotient obtained by dividing the dividend by the divisor. This makes it possible to implement a fast divider with a configuration simpler than that of a conventional divider which feeds back the outputs of multipliers many times depending on the accuracy required, which involves delay times in the multiplication and makes the configuration complicated.
