be implemented in the Cyclone III device family.
In addition to the embedded multipliers in the Cyclone III device family, you can
implement soft multipliers by using the M9K memory blocks as look-up tables
(LUTs). The LUTs contain partial results from the multiplication of input data with
coefficients that implement variable depth and width high-performance soft
multipliers for low-cost, high-volume DSP applications. The availability of soft
multipliers increases the number of available multipliers in the device.
