Figure 6–13. Complex Multiplier Implemented Using Two-Multiplier Adder
Mode
Four-Multiplier Adder Mode
In the four-multiplier adder mode, which you can use for 1-dimensional
and 2-dimensional filtering applications, the DSP block adds the results
of two adder/subtractor/accumulators in a final stage (the summation
block).

You can only use the adder block if it follows multiplication
operations.
