The fundamental building block of Arria II GX devices is a pair of 18 × 18-bit
multipliers followed by a first-stage 37-bit addition and subtraction unit, as shown in
Equation 4–1
represented in 2’s complement format only.
Equation 4–1. Multiplier Equation
The structure shown in
such as complex multipliers and 36 × 36 multipliers, as described in later sections.
Each Arria II GX 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. For a detailed diagram of the DSP block,
refer to
Following the two-multiplier adder units are the pipeline registers, the second-stage
adders, and an output register stage. You can configure the second-stage adders to
provide the alternative functions shown in
block.
