Table 4–1. Number of Embedded Multipliers in Cyclone IV Devices
In addition to the embedded multipliers in Cyclone IV devices, 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.

in FPGA Devices.
