A single chip parallel multiplier by MOS technology

A parallel multiplier design based on the five-counter cell is discussed. A design optimization for the performance in speed is proposed at the logic design level which is developed into an MOS circuit design. The comparison of the five-counter cell design and the full adder cell design reveals that the proposed design is most useful with pass gate logic and results in high-speed multiplication (approximately twice as fast as that of the full adder design) with a moderate increase in hardware complexity. With the five-counter design, an improvement in the hardware complexity of a squarer can be expected
