Cyclone II Memory Blocks chapter in Volume 1 of the Cyclone II Device
Handbook.
Cyclone II devices have embedded multiplier blocks optimized for
multiplier-intensive digital signal processing (DSP) functions, such as
finite impulse response (FIR) filters, fast Fourier transform (FFT)
functions, and discrete cosine transform (DCT) functions. You can use the
embedded multiplier in one of two basic operational modes, depending
on the application needs:
