ABSTRACT:
A multiplier for multiplying a fixed point multiplicand by a floating point multiplier utilizes decode logic which provides control signals related to two numbers, the sum of which is approximately equal to the mantissa of the multiplier. The multiplicand is separately left shifted in two circuits, responsive to the control signals, by a number of places respectively corresponding to the values of said two numbers. The shift circuit outputs are summed algebraically in an adder. The sum is then shifted by a number of places and in a direction determined respectively by the magnitude and sign of the power of the floating point multiplier. The result is a close approximation of the desired multiplication product. The multiplier advantageously is employed in an electronic musical instrument.
