In Stratix IV devices, the fundamental building block is a pair of 18 × 18-bit
multipliers followed by a first-stage 37-bit addition/subtraction unit, as shown in
Equation 4–1
All signed numbers, input, and output data are represented in 2’s-complement format
only.

Figure 4–2. Basic Two-Multiplier Adder Building Block
The structure shown in
such as complex multipliers and 36 × 36 multipliers, as described in later sections.
Each Stratix IV DSP block contains four two-multiplier adder units (2 two-multiplier
adder units per half block). Therefore, there are eight 18 × 18 multiplier functionalities
per DSP block.
