A 10 ns 54×54-bit parallel structured full array multiplier with 0.5 μm CMOS technology

A 54-b×54-b multiplier fabricated in double metal 0.5-μm CMOS technology is described. A 10-ns multiplication time has been achieved by employing a 4-2 compressor, a carry select adder, and a carry lookahead adder. The 54-b×54-b full array is adopted to complete the multiplication within one latency. This multiplier is intended for double-precision floating-point data processing based on IEEE standards up to a clock range of 100 MHz. The multiplier has integrated 81600 transistors in an active area of 3.62 mm×3.45 mm
