Baseband processing is key to DRM
receiver
At IFA 2005 Analog Devices and digital radio receiver manufacturer AFG Engineering demonstrated the first Blackfin-based digital radio receiver conforming to the Digital Radio Mondiale standard.
Last week at IFA 2005, Analog Devices and digital radio receiver manufacturer AFG Engineering demonstrated the first Blackfin-based digital radio receiver conforming to the DRM (Digital Radio Mondiale) standard The world's only nonproprietary 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

The next-generation Blackfin processor family is claimed to deliver twice the performance at half the power consumption of conventional DSPs and embedded processors.

Analog Devices has expanded its Blackfin processor family to include a new class of embedded processor, the ADSP-BF561, which integrates two identical Blackfin cores.
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-bitrate 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 knowhow 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 analogue and digital radio standards, leveraging the programmability of the Blackfin".
Commented Mike Haidar, General Manager, Software and Systems Technology, Analog Devices: "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 4.5 or 5kHz - or wider bandwidths, such as 18 or 20kHz.
