| ANALOG DEVICES’ BLACKFIN PROCESSOR POWERS BASEBAND PROCESSING FOR NEW
DRM RECEIVER | | | |
IFA 2005, Berlin Germany - Analog Devices, Inc. and AFG Engineering GmbH
today demonstrated at IFA 2005 the first Blackfin®-based digital radio receiver conforming to the DRM (Digital Radio
Mondiale) standard. The world’s only non-proprietary digital radio system for short-wave, AM/medium-wave and
long-wave, the DRM standard has been endorsed by the ITU (International Telecommunication Union), IEC (International
Engineering Consortium) and ETSI (European Telecommunications Standards Institute) and is ideal for fixed and
portable radio receivers and car radio receivers.
AFG selected Blackfin because of its baseband processing
capability and its flexibility in processing multiple audio standards. The DRM standard mandates three types of
audio decoders: MPEG4 AAC+ (including SBR) for high-quality audio; CELP for high-quality speech coding; and, HVXC
speech coding for low bit-rate speech coder. Blackfin’s high performance architecture allows AFG the means to
process multiple decoders greatly reducing bill of materials while retaining the robust needs of the DRM
standard.
“The Blackfin Processor and ADI’s software and system know-how enabled us to develop
and introduce the first prototypes of DRM consumer radio receivers,” said Joachim Bamberger, Managing Director, AFG.
“Driven by the Blackfin Processor, this platform enables receiver manufacturers to build low-cost and low-power
consumer and automotive radio receivers. In addition to supporting DRM, this platform also supports other analog and
digital radio standards, leveraging the programmability of the Blackfin.”
Commented Mike Haidar,
General Manager, Software and Systems Technology, Analog Devices, Inc.: “Analog Devices prides itself on developing
products that help drive new innovations in technology. The ability to offer a bundled solution that includes the
Blackfin processor with robust DRM application software has been the key factor for success in this very demanding
market.”
DRM uses existing AM broadcasting bands, but provides FM quality audio. Because of its
flexibility, DRM can operate over limited bandwidth – as little as 4.5kHz or 5kHz – or wider bandwidths, such as 18
or 20kHz.
Blackfin in Convergent Processing Analog Devices’ Blackfin® Processors embody
a new breed of 16/32-bit embedded processor with the industry’s highest performance and power efficiency for
applications where a convergence of capabilities – multiformat audio, video, voice and image processing; multi-mode
baseband and packet processing; and real-time security and control processing – are critical. It is this powerful
combination of software flexibility and scalability that has gained Blackfin widespread adoption in convergent
applications such as portable and networked media players; automotive telematics, infotainment and driver
assistance; satellite and terrestrial radio; and networked security systems. |
