Bit multipliers, Bit multipliers -4 – Altera MAX 10 Embedded Multipliers User Manual
Page 8
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.
9-Bit Multipliers
You can configure each embedded multiplier to support two 9 × 9 independent multipliers for input
widths of up to 9 bits.
The following figure shows the embedded multiplier configured to support two 9-bit multipliers.
