You can configure each embedded multiplier to support a single 18 × 18 multiplier for
input widths of 10 to 18 bits.
Figure 4–3
All 18-bit multiplier inputs and results are independently sent through registers. The
multiplier inputs can accept signed integers, unsigned integers, or a combination of
both. Also, you can dynamically change the signa and signb signals and send these
signals through dedicated input registers.
