Method and apparatus for performing a multiplication or division operation in an electronic circuit

摘要

A multiplication or division operation X.K or X.1/K is performed in an electronic circuit. A software circuit area of the circuit calculates a digit shift sv such that p^sv is an approximate value for K. In a hardware circuit area, the value X is shifted sv digits to the left in the case of multiplication or sv digits to the right in the case of division. The software circuit area calculates a suitable correction factor Kf. The value X is multiplied by the correction factor Kf.
