A 16 bitx16 bit pipelined multiplier macrocell

A 16 bit/spl times/16 bit pipelined multiplier implemented in a two-layer metal 1.5 /spl mu/m CMOS/BULK technology has been developed. The design is based on the well-known modified Booth algorithm and is capable of operating at a 25 MHz clock rate. The multiplier is designed to be used as a macrofunction within larger chip designs. A structured design approach has been utilized so that reconfiguration of the basic array can be performed. The multiplier macrocell measures 1.7 mm/spl times/1.7 mm.
