• In the ‘Signed/Unsigned’ options the operands can be switched between signed and unsigned on every cycle.
• In the ‘Add/Sub’ option the Accumulator can be switched between addition and subtraction on every cycle.
• The loading of operands can switch between parallel and serial operations.
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 2-20 shows the MULT sysDSP element.
