3.1.2. The 18 × 18 Sum of 2 Mode

In 18 × 18 Sum of 2 Mode, the Arria 10 Native Fixed Point DSP IP core enables the top and bottom multipliers and generates a result from addition or subtraction between the 2 multipliers. The sub dynamic control signal controls an adder to perform the addition or subtraction operations. The resulta output width of the Arria 10 Native Fixed Point DSP IP core can support up to 64 bits when you enable accumulator/output cascade. This mode applies the equation of resulta =[±(ax * ay) + (bx * by)].
