You can implement soft multipliers by using the M9K memory blocks as look-up tables (LUTs). The
LUTs contain partial results from multiplying input data with coefficients implementing 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.

These columns show the number of 9 x 9 or 18 x 18 multipliers for each device. The total number of
multipliers for each device is not the sum of all the multipliers.
(2)
Soft multipliers are implemented in sum of multiplication mode. M9K memory blocks are configured with
18-bit data widths to support 16-bit coefficients. The sum of the coefficients requires 18-bits of resolution to
account for overflow.
(3)
The total number of multipliers may vary, depending on the multiplier mode you use.
