Next-Generation SigmaDSP® Processor Unveiled By Analog Devices

Business Wire
Automotive-qualified with integrated audio
peripherals, ADAU1452 is designed for compact, standalone consumer
audio and automotive infotainment applications.
Analog Devices, Inc. (NASDAQ: ADI), a global leader in
high-performance semiconductors for signal processing applications,
introduced today an audio-centric addition to its SigmaDSP®
processor line that far exceeds the signal processing capabilities
of earlier SigmaDSP devices. Improvements in hardware and software
enable the ADAU1452 SigmaDSP processor to execute up to three times
more audio processing algorithms than its predecessors, providing
system designers with more flexibility to improve the audio
performance of their products.
The new processor features a unique hardware architecture that
is optimized for efficient processing of audio signal flows created
using ADI’s award winning, user-friendly SigmaStudio™ graphical
programming tool. The ADAU1452 is the first product in the SigmaDSP
family of audio processors to allow both time-domain and
frequency-domain processing simultaneously. This extends the range
of signal processing techniques that can be implemented to solve
system design problems.
The ADAU1452 is suited to a variety of products in applications
such as automotive infotainment (amplifiers and head units),
consumer audio (soundbars, sub-woofers and active speakers), and
professional audio (amplifiers, mixers and effects units).

The ADAU1452 features a 1.2-volt, 32-bit DSP core that runs at
frequencies up to 294.912 MHz and executes up to 6,144 instructions
per sample (the approximate equivalent of 1.2 GMAC/s or 295 MIPS)
at the standard sample rate of 48 kHz. The streamlined core
architecture allows for more than 3,000 biquad filters to be
executed in a single program. The expanded data memories can
accommodate FIR filters of up to 24,000 taps in length. The
ADAU1452 SigmaDSP’s clock generators, on-board asynchronous
sample-rate converters and flexible hardware audio routing matrix
greatly simplify the design of complex multi-rate audio systems,
while the clock hardware and integer phase-locked loop (PLL)
generate up to 15 audio sample rates simultaneously.
The ADAU1452 interfaces to a wide range of data converters,
digital audio devices, amplifiers, and control circuitry, because
of its configurable 48-channel, 32-bit serial ports, stereo S/PDIF
interfaces, and multi-purpose input/output pins. It can also
directly interface with up to four MEMS microphones using a PDM
interface and integrated decimation filter.
Independent slave and master I2C/SPI control ports allow the
ADAU1452 not only to be programmed and configured by an external
master device, but also to act as the master and directly configure
external slave devices. This, combined with self-boot
functionality, enables the design of compact standalone systems
that do not require an external input to operate.
