Stratix II Device Handbook, Volume 1
The most commonly used DSP functions are FIR filters, complex FIR
filters, 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 devices provide DSP blocks to meet the arithmetic
requirements of these functions.
Each Stratix II device has from two to four columns of DSP blocks to
efficiently implement DSP functions faster than ALM-based
implementations. Stratix II devices have up to 24 DSP blocks per column
(see

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