3.6.2.1. 18 x 18 Complex Multiplier

For 18 x 18 complex multiplication mode, you require two variable precision DSP blocks to perform this multiplication.

You can implement the imaginary part [(a × d) + (b × c)] in the first variable precision DSP block, and you can implement the real part [(a × c) – (b × d)] in the second variable precision DSP block.
