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. Arria GX devices provide DSP blocks to meet the arithmetic requirements
of these functions.
Each Arria GX device has two to four columns of DSP blocks to efficiently implement
DSP functions faster than ALM-based implementations. Each DSP block can be
configured to support up to:
