Data A [17..0]
Data B [17..0]
All 18-bit multiplier inputs and results can be sent independently through
registers. The multiplier inputs can accept signed integers, unsigned
integers, or a combination of both. Additionally, you can change the
signa and signb signals dynamically and send these signals through
dedicated input registers.
9-Bit Multipliers
You can configure each embedded multiplier to support two 9 x 9
independent multipliers for input widths of up to 9 bits.
