DSP blocks can also implement one 36 × 36-bit multiplier in multiplier
mode. DSP blocks use four 18 × 18-bit multipliers combined with
dedicated adder and internal shift circuitry to achieve 36-bit
multiplication. The input shift register feature is not available for the
36 × 36-bit multiplier. In 36 × 36-bit mode, the device can use the register
that is normally a multiplier-result-output register as a pipeline stage for
the 36 × 36-bit multiplier.
