When the signa and signb signals are unused, the Quartus II software sets the
multiplier to perform unsigned multiplication by default.
You can register the embedded multiplier output using output registers in either
18- or 36-bit sections, depending on the operational mode of the multiplier. The
following control signals are available for each output register in the embedded
multiplier:
■
■
■
All input and output registers in a single embedded multiplier are fed by the same
clock, clock enable, and asynchronous clear signals.
You can use an embedded multiplier block in one of two operational modes,
depending on the application needs:
■
■
You can also use embedded multipliers of the Cyclone III device family to implement
multiplier adder and multiplier accumulator functions, in which the multiplier
portion of the function is implemented using embedded multipliers, and the adder or
accumulator function is implemented in logic elements (LEs).
