Description

ABSTRACT:
A divider circuit which calculates an integral quotient of an integral divisor and an integral dividend. A first multiplication unit calculates products of the integral divisor and all n-bit pattern values of an n-bit pattern, where n is a predetermined number and the n-bit pattern values respectively correspond to the calculated products. A calculation unit sets the integral dividend as an initial value of an operational integer, specifies a product among the products calculated by the first multiplication unit of which the subordinate n-bit value is equal to the subordinate n-bit value of the operational integer, and calculates a difference of the operational integer and the specified product. When the difference calculated by the calculation unit is not zero, an activation unit sets a new operational integer by canceling the subordinate n bits of the difference and causes the calculation unit to set the integral dividend, specify a product and calculate a difference based on the new operational integer. An output unit successively takes n-bit pattern values respectively corresponding to products specified by the calculation unit, and outputs these n-bit pattern values as the quotient when the difference calculated by the calculation unit is zero.
