Notes to
(1) This mode also supports loopback mode. In loopback mode, the number of loopback multipliers per DSP block is two. You can use the remaining
(2) Unsigned value is also supported, but you must ensure that the result can be contained in 36 bits.
(3) Dynamic shift mode supports arithmetic shift left, arithmetic shift right, logical shift left, logical shift right, and rotation operation.
(4) Dynamic shift mode operates on a 32-bit input vector, but the multiplier width is configured as 36 bits.

You can use each Arria II DSP block in one of six basic operational modes.
lists the six basic operational modes and the number of multipliers that you can
implement in a single DSP block.
The DSP block consists of two identical halves (top-half and bottom-half). Each half
has four 18 × 18 multipliers.
The Quartus
of the multipliers. After making the appropriate parameter settings with the
megafunction’s MegaWizard
automatically configures the DSP block.
Arria II DSP blocks can operate in different modes simultaneously. Each half block is
fully independent except for the sharing of the clock, ena, and the aclr signals. For
example, you can break down a single DSP block to operate a 9 × 9 multiplier in one
half block and an 18 × 18 two-multiplier adder in the other half block. This increases
DSP block resource efficiency and allows you to implement more multipliers in an
Arria II device. The Quartus II software automatically places multipliers that can
share the same DSP block resources in the same block.
