In multiply accumulate mode, the second-stage adder is configured as a 44-bit
accumulator or subtractor. The output of the DSP block is looped back to the
second-stage adder and added or subtracted with the two outputs of the first-stage
adder block according to
Figure 4–18
A single DSP block can implement up to two independent 44-bit accumulators.
Use the dynamic accum_sload control signal to clear the accumulation. A logic 1
value on the accum_sload signal synchronously loads the accumulator with the
multiplier result only, and a logic 0 enables accumulation by adding or subtracting
the output of the DSP block (accumulator feedback) to the output of the multiplier
and first-stage adder.
