This section describes the operation modes of Arria II devices.
In the independent input and output multiplier mode, the DSP block performs
individual multiplication operations for general-purpose multipliers.
9-Bit, 12-Bit, and 18-Bit Multiplier
You can configure each DSP block multiplier for 9-bit, 12-bit, or 18-bit multiplication.
A single DSP block can support up to eight individual 9 × 9 multipliers, six 12 × 12
multipliers, or up to 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.
