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 use the multiplier as the
fundamental building block. Additionally, some applications need
specialized operations such as multiply-add and multiply-accumulate
operations. Stratix II GX devices provide DSP blocks to meet the
arithmetic requirements of these functions.
Each Stratix II GX device has two to four columns of DSP blocks to
efficiently implement DSP functions faster than ALM-based
implementations. Stratix II GX devices have up to 24 DSP blocks per
column (see

As indicated, the Stratix II GX DSP block can support one 36 × 36-bit
multiplier in a single DSP block, and is true for any combination of
signed, unsigned, or mixed sign multiplications.
