The number of embedded multipliers per column and the number of
columns available increases with device density.
number of embedded multipliers in each Cyclone III device and the
multiplier modes that you can implement.
In addition to the embedded multipliers, you can also implement soft
multipliers using Cyclone III M9K memory blocks. You can use M9K
blocks as look-up tables (LUTs) that contain partial results from the
multiplication of input data with coefficients that implements variable
depth/width high-performance soft multipliers for low-cost,
high-volume DSP applications. The availability of soft multipliers
increases the number of multipliers available within the device.
shows the total number of multipliers available in Cyclone III devices
using embedded multipliers and soft multipliers.
