3.6.2. Independent Complex Multiplier Mode

The Cyclone® V devices support the 18 x 19 complex multiplier mode using two Cyclone® V variable-precision DSP blocks.

Figure 27. Sample of Complex Multiplication Equation

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.
