Cyclone V Device Overview

Variable-Precision DSP Block

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 and 27 x 27 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
  • Fully independent Efficient support for single-precision floating point arithmetic
  • The inferability of all modes by the Intel® Quartus® Prime design software
Table 16.  Variable-Precision DSP Block Configurations for Cyclone® V Devices
Usage Example Multiplier Size (Bit) DSP Block Resource
Low precision fixed point for video applications Three 9 x 9 1
Medium precision fixed point in FIR filters Two 18 x 18 1
FIR filters and general DSP usage Two 18 x 18 with accumulate 1
High precision fixed- or floating-point implementations One 27 x 27 with accumulate 1

You can configure each DSP block during compilation as independent three 9 x 9, two 18 x 18, or one 27 x 27 multipliers. With a dedicated 64 bit cascade bus, you can cascade multiple variable-precision DSP blocks to implement even higher precision DSP functions efficiently.
