Stratix Device Handbook, Volume 1
Output Selection Multiplexer
The outputs from the various elements of the adder/output block are
routed through an output selection multiplexer. Based on the DSP block
operational mode and user settings, the multiplexer selects whether the
output from the multiplier, the adder/subtractor/accumulator, or
summation block feeds to the output.
Output Registers
Optional output registers for the DSP block outputs are controlled by four
sets of control signals: clock[3..0], aclr[3..0], and ena[3..0].
Output registers can be used in any mode.
Modes of Operation
The adder, subtractor, and accumulate functions of a DSP block have four
modes of operation:

Simple Multiplier Mode
In simple multiplier mode, the DSP block drives the multiplier sub-block
result directly to the output with or without an output register. Up to four
18 × 18-bit multipliers or eight 9 × 9-bit multipliers can drive their results
directly out of one DSP block. See
Simple multiplier
Multiply-accumulator
Two-multipliers adder
Four-multipliers adder
Each DSP block can only support one mode. Mixed modes in the
same DSP block is not supported.
