Abstract
The design of overturned stairs (OS) tree multipliers for 2's complement numbers is presented. A 2's complement multiplication algorithm other than the Baugh-Wooley method is used. A 16*16 multiplier design is studied in detail. The generation of arbitrary N*N multipliers is addressed. It is shown that OS tree multipliers can be systematically designed. A regular and compact layout can be obtained. Tree-type design leads to high-speed computation but increases the chip area requirement. The authors give a comparison between their design and a conventional one. >
