3.6.2.3. 18 x 25 Complex Multiplier

Arria® V GZ devices support an individual 18 x 25 complex multiplication mode.

A 27 x 27 multiplier allows you to implement an individual 18 x 25 complex multiplication mode with three variable precision DSP blocks only. The pre-adder feature is automatically enabled for you to implement an individual 18 x 25 complex multiplication mode efficiently.
