Stratix Device Handbook, Volume 1
The most commonly used DSP functions are finite impulse response (FIR)
filters, complex FIR filters, infinite impulse response (IIR) filters, fast
Fourier transform (FFT) functions, direct cosine transform (DCT)
functions, and correlators. All of these blocks have the same fundamental
building block: the multiplier. Additionally, some applications need
specialized operations such as multiply-add and multiply-accumulate
operations. Stratix devices provide DSP blocks to meet the arithmetic
requirements of these functions.
Each Stratix device has two columns of DSP blocks to efficiently
implement DSP functions faster than LE-based implementations. Larger
Stratix devices have more DSP blocks per column (see
DSP block can be configured to support up to:
As indicated, the Stratix DSP block can support one 36 × 36-bit multiplier
in a single DSP block. This is true for any matched sign multiplications
(either unsigned by unsigned or signed by signed), but the capabilities for
dynamic and mixed sign multiplications are handled differently. The
following list provides the largest functions that can fit into a single DSP
block.
