Cyclone V devices feature a variable-precision DSP block that supports these features:
Configurable to support signal processing precisions ranging from 9 x 9, 18 x 18, 27 x 27, and 36 x 36
bits natively
A 64-bit accumulator
A hard preadder that is available in both 18- and 27-bit modes
Cascaded output adders for efficient systolic finite impulse response (FIR) filters
Internal coefficient register banks, 8 deep, for each multiplier in 18- or 27-bit mode
Fully independent multiplier operation
A second accumulator feedback register to accommodate complex multiply-accumulate functions
Efficient support for single-precision floating point arithmetic
The inferability of all modes by the Quartus II design software
