MULTADD sysDSP Element
In this case, the operands A0 and B0 are multiplied and the result is added/subtracted with the result of the multi-
plier operation of operands A1 and A2. The user can enable the input, output and pipeline registers. Figure 2-20
shows the MULTADD sysDSP element.

MULTADDSUM sysDSP Element
In this case, the operands A0 and B0 are multiplied and the result is added/subtracted with the result of the multi-
plier operation of operands A1 and B1. Additionally the operands A2 and B2 are multiplied and the result is added/
subtracted with the result of the multiplier operation of operands A3 and B3. The result of both addition/subtraction
are added in a summation block. The user can enable the input, output and pipeline registers. Figure 2-21 shows
the MULTADDSUM sysDSP element.
