Correction circuit for approximate quotient.

摘要

An approximate quotient-correcting circuit wherein ah approximate quotient QH, a divisor D, and the least significant bit of the fraction part of a dividend N are read out; the approximate quotient QH and the divisor D are multiplied; it is decided that the lower m digits of QH x D are not all 'O' and that the m-th significant bit of QH x D is coincident with the m-th significant bit of N; and when the result of the decision is positive, QH - 2-m is provided as a quotient.
