DSP block multipliers can optionally feed an adder/subtractor or
accumulator within the block depending on the configuration. This
makes routing to LEs easier, saves LE routing resources, and increases
performance, because all connections and blocks are within the DSP
block. Additionally, the DSP block input registers can efficiently
implement shift registers for FIR filter applications.

Table 2–13. DSP Blocks in Stratix Devices
Device
Each device has either the number of 9 × 9-, 18 × 18-, or 36 × 36-bit multipliers
shown. The total number of multipliers for each device is not the sum of all the
multipliers.
The number of supported multiply functions shown is based on signed/signed
or unsigned/unsigned implementations.
