Double Multiplier
You can configure the Arria II GX DSP block to support an unsigned 54 × 54-bit
multiplier that is required to compute the mantissa portion of an IEEE double
precision floating point multiplication. You can build a 54 × 54-bit multiplier using
basic 18 × 18 multipliers, shifters, and adders. To efficiently use built-in shifters and
adders in the Arria II GX DSP block, a special double mode (partial 54 × 54 multiplier)
is available that is a slight modification to the basic 36 × 36 multiplier mode.
