Fast multiply and divide for a VLSI floating-point unit
This paper presents the design of a fast and area-efficient multiply-divide unit used in building a VLSI floating-point processor (FPU), conforming to the IEEE standard 754. Details of the algorithms, implementation techniques and design tradeoffs are presented, The multiplier and divider are implemented in 2 micron CMOS technology with two layers of metal, and occupy 23 square mm (23% of the entire FPU). We expect to perform extended-precision multiplication and division in 1.1 and 2.8 microseconds, respectively.
