3.1.5. The 27 × 27 Mode
When configured as 27 × 27 mode, the Arria 10 Native Fixed Point DSP IP core enables a 27(signed/unsigned) × 27(signed/unsigned) multiplier. The output bus can support up to 64 bits with accumulator/output cascade enabled. This mode applies the equation of resulta = ax * ay.
