A circuit multiplies or divides pulse code modulation (PCM) samples in D2 format. An exponent adder/subtractor provides the sum/difference of the exponents of the two numbers. A mantissa multiplier/divider circuit determines the product/quotient of the two mantissas and a sign generator provides a sign...http://www.google.fr/patents/US4716538?utm_source=gb-gplus-shareBrevet US4716538 - Multiply/divide circuit for encoder PCM samples
