DSP Blocks in Stratix II and Stratix II GX Devices
The number of DSP blocks per column and the number of columns
available increases with device density. Table 6–1 shows the number of
DSP blocks in each Stratix II device and the multipliers that you can
implement.

Note to Table 6–1:
(1) 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.
Table 6–2 shows the number of DSP blocks in each Stratix II GX device
and the multipliers that you can implement.
