You can also use embedded multipliers of Cyclone IV devices to implement multiplier
adder and multiplier accumulator functions, in which the multiplier portion of the
function is implemented with embedded multipliers, and the adder or accumulator
function is implemented in logic elements (LEs).
You can configure each embedded multiplier to support a single 18 × 18 multiplier for
input widths of 10 to 18 bits.
Figure 4–3
All 18-bit multiplier inputs and results are independently sent through registers. The
multiplier inputs can accept signed integers, unsigned integers, or a combination of
both. Also, you can dynamically change the signa and signb signals and send these
signals through dedicated input registers.
You can configure each embedded multiplier to support two 9 × 9 independent
multipliers for input widths of up to 9 bits.
shows the embedded multiplier configured to support an 18-bit multiplier.
