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 GX devices provide DSP blocks to meet the arithmetic
requirements of these functions.
Each Stratix GX device has two columns of DSP blocks to efficiently
implement DSP functions faster than LE-based implementations. Larger
Stratix GX devices have more DSP blocks per column (see
Each DSP block can be configured to support up to:

As indicated, the Stratix GX 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

Four 18 × 18-bit multipliers
One 36 × 36-bit multiplier
