3.1.1.2. 27 × 27 Independent Multiplier
The 27 x 27 independent multiplier mode uses the equation of resulta = ay * ax.
Figure 7. One 27 × 27 Independent Multiplier Mode per Variable Precision DSP Block for Intel® Stratix® 10 DevicesIn this mode, the resulta can be up to 64 bits when combined with a chainout adder or accumulator.
