Abstract
A calculating apparatus receives four operands ('a, b, c and d') simultaneously. A first multiplier/divider performs the calculation of a*b or a.div.b and provides an output u. A second multiplier/divider performs the calculation of c*d or c.div.d and provides an output v. An adder/subtractor receives u and v and performed the calculation of u+v and u-v. A controller controls the operation of the first and second multiplier/divider to select the operation of multiplication or division.
