  • Patent number: 8819094
    Abstract: The technology is a division circuit with decreased circuit area. An embodiment includes an integrated circuit implementing multiplicative division of a dividend input and a divisor input. The integrated circuit includes a lookup table circuit and multiplier circuits. The lookup table circuit providing an approximation of a reciprocal of a divisor input. The multiplier circuits receive the approximation and refine a quotient output of the dividend input and a divisor input. At least one of the multiplier circuits is a squaring circuit implementing multiplication with a reduced number of intermediate partial products. The reduced number of intermediate partial products prevent the squaring circuit from multiplication of any two unequal numbers and limiting the squaring circuit to multiplication of a same number by the same number.
