Figure 2-20. MAC sysDSP Element
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 2-21
shows the MULTADD sysDSP element.
