MULT sysDSP Element
This multiplier element implements a multiply with no addition or accumulator nodes. The two operands, A and B,
are multiplied and the result is available at the output. The user can enable the input/output and pipeline registers.
Figure 2-18 shows the MULT sysDSP element.
Figure 2-18. MULT sysDSP Element
MAC sysDSP Element
In this case the two operands, A and B, are multiplied and the result is added with the previous accumulated value.
This accumulated value is available at the output. The user can enable the input and pipeline registers but the out-
put register is always enabled. The output register is used to store the accumulated value. A registered over
fl
ow
signal is also available. The over
fl
ow conditions are provided later in this document. Figure 2-19 shows the MAC
sysDSP element.
