You can configure each embedded multiplier to support two 9 × 9 independent
multipliers for input widths of up to 9 bits.

multipliers.
All 9-bit multiplier inputs and results are independently sent through registers. The
multiplier inputs can accept signed integers, unsigned integers, or a combination of
both. Two 9 × 9 multipliers in the same embedded multiplier block share the same
signa and signb signal. Therefore, all the Data A inputs feeding the same
embedded multiplier must have the same sign representation. Similarly, all the
Data B inputs feeding the same embedded multiplier must have the same sign
representation.
