Embedded

Multipliers

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:

■

One 18-bit multiplier

■

Up to two independent 9-bit multipliers
