Abstract
A semiconductor integrated circuit so arranged that selection is made out of output signals of a decision circuit which determines the levels of analog values inputted as an object for multiplication and multiplication is carried out with respect to the selected signal and the digital value inputted as an object for multiplication, the result of the multiplication being added with the digital value as shifted to the higher position of specified bits, a multiplication result being thereby calculated with respect to the analog value and the digital value, whereby the required area of wiring connections is reasonably reduced and faster operation is assured.
