For 18 x 19 complex multiplication mode, you require two variable precision DSP blocks to perform this multiplication.

The imaginary part [(a × d) + (b × c)] is implemented in the first variable precision DSP block, while the real part [(a × c) - (b × d)] is implemented in the second variable precision DSP block.
