3.6.1. Independent Multiplier Mode

In independent input and output multiplier mode, the variable precision DSP blocks perform individual multiplication operations for general purpose multipliers.

You can configure each variable precision DSP block multiplier for 9-, 16-, 18-, 27-Bit, or 36 x 18 multiplication.

For some operational modes, the unused inputs require zero padding.
