Figure 4–10. 9-Bit Independent Multiplier Mode Shown for a Half Block
The multiplier operands can accept signed integers, unsigned integers, or a
combination of both. You can change the signa and signb signals dynamically and
can register the signals in the DSP block. Additionally, the multiplier inputs and
results can be registered independently. You can use the pipeline registers within the
DSP block to pipeline the multiplier result, increasing the performance of the DSP
block.
The rounding and saturation logic unit is supported for 18-bit independent multiplier
mode only.
