Traditionally, designers had to make a trade-off between the flexibility of
off-the-shelf digital signal processors and the performance of custom-
built devices. Altera Stratix and Stratix GX devices eliminate the need
for this trade-off by providing exceptional performance combined with
the flexibility of programmable logic devices (PLDs). Stratix and
Stratix GX devices have dedicated digital signal processing (DSP) blocks,
which have high-speed parallel processing capabilities, that are
optimized for DSP applications. DSP blocks are ideal for implementing
DSP applications that need high data throughput.
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, discrete cosine transform (DCT)
functions, and correlators. These functions are the building blocks for
more complex systems such as wideband code division multiple access
(W-CDMA) basestations, voice over Internet protocol (VoIP), and high-
definition television (HDTV).
Although these functions are complex, they all use similar building
blocks such as multiply-adders and multiply-accumulators. Stratix and
Stratix GX DSP blocks combine five arithmetic operations—
multiplication, addition, subtraction, accumulation, and summation—to
meet the requirements of complex functions and to provide improved
performance.
This chapter describes the Stratix and Stratix GX DSP blocks, and
explains how you can use them to implement high-performance DSP
functions. It addresses the following topics:
