    Hi,


    Yes, it is possible, you can use the Native Fixed-Point DSP Intel Arria 10 FGPA IP to configure it.

    Resulta = (ay+az)* ax

    Resultb = (by+bz)* bx


    Regards -SK

      According to Arria 10 DSP document, resultb is only available in m18×18_full operational mode, and in this mode's section it says the function is:

      • resulta = ax * ay
      • resultb = bx * by

      Regards,

    You can also refer to section 3.2.2 pre-adder that stated it can configure in 2 independent 18 bits pre-adder. You may explore it from the " Pre-adder" tab in Native Fixed-Point DSP Intel Arria 10 FPGA IP.
