The first architecture consists of a pure array multiplier that was modified to handle the sign bits in 2’s complement and uses a radix-4 encoding to reduce the partial product lines. The second architecture implemented was the widely used Modified Booth multiplier. We describe a design methodology to physically implement these architectures in a pipelined and non-pipelined form, obtaining area, power consumption and delay results. Up to now only results at the logic level were presented in previous work. The performance of pipelined array architecture is compared with the pipelined Modified Booth. We compare the physical implementations in terms of area, power and delay. The results show that the new pipelined array multiplier can be significantly more efficient, with close to 16% power savings and 55% power savings when considering non-pipelined architectures.
