ABSTRACT:
A circuit multiplies pulse code modulation (PCM) samples in D2 format. An exponent adder provides the sum of the exponents of the two numbers. A mantissa multiplier circuit determines the product of the two mantissas and a sign generator provides a sign value for the resultant product of the two numbers. A normalizer circuit ensures that the product mantissa has a predetermined range of values.
