Stratix II Device Handbook, Volume 1
Table 2–5
DSP block multipliers can optionally feed an adder/subtractor or
accumulator in the block depending on the configuration. This makes
routing to ALMs easier, saves ALM routing resources, and increases
performance, because all connections and blocks are in the DSP block.
Additionally, the DSP block input registers can efficiently implement shift
registers for FIR filter applications, and DSP blocks support Q1.15 format
rounding and saturation.
