A High Speed Double Precision Floating Point Multiplier Design Based on FPGA
a high speed double precision floating point multiplier based on FPGA is presented.The proposed design adopted radix-4 Booth coder to obtain partial products
then an optimal Wallace tree compression architecture is exploited on these partial products to get a pseudo-sum and pseudo-carry
which are partially accumulated in a parallel approach to generate mantissa of the product.The design with 5-stage pipeline architecture can achieve 123.32MHz targeted at a Cyclone Ⅱ EP2C35F672C6 device.By taking the same optimization efforts
the design gets 11% enhancement on operating frequency over an Altera IP core using DSP multipliers
while about 67% over such IP core without using DSP multipliers.
