Independent Multiplier Modes
9-, 12-, and 18-Bit Multiplier
The second-stage and output registers are triggered by the positive edge of the clock
signal and are cleared after power up. The following DSP block signals control the
output registers within the DSP block:

This section contains an explanation of different operational modes in Stratix IV
devices.
In independent input and output multiplier mode, the DSP block performs individual
multiplication operations for general-purpose multipliers.
You can configure each DSP block multiplier for 9-, 12-, or 18-bit multiplication. A
single DSP block can support up to eight individual 9 × 9 multipliers, six individual
12 × 12 multipliers, or four individual 18 × 18 multipliers. For operand widths up to
9 bits, a 9 × 9 multiplier is implemented. For operand widths from 10 to 12 bits, a
12 × 12 multiplier is implemented, and for operand widths from 13 to 18 bits, an
18 × 18 multiplier is implemented. This is done by the Quartus II software by
zero-padding the LSBs.
