Table 2–10. Number of Embedded Multipliers in Cyclone II Devices
Each device has either the number of 9 × 9-, or 18 × 18-bit multipliers shown. The total number of multipliers for
each device is not the sum of all the multipliers.

Table
2–10:
Multiplier Columns
Embedded
Embedded multipliers can operate at up to 250 MHz (for the fastest speed
grade) for 18 × 18 and 9 × 9 multiplications when using both input and
output registers.
Each Cyclone II device has one to three columns of embedded multipliers
that efficiently implement multiplication functions. An embedded
multiplier spans the height of one LAB row.
of embedded multipliers in each Cyclone II device and the multipliers
that can be implemented.
The embedded multiplier consists of the following elements:
