ADI Processors Power Audi A5 In-Car Entertainment

German automaker Audi has selected ADI's Blackfin and SHARC processors for the in-cabin entertainment systems of its new A5 Coupe. The new A5 features the Audi Symphony and Concert advanced digital radios, a Digital Audio Broadcast (DAB) option, a 6-CD changer, and a MultiMedia Device Interface for connecting to personal media players. ADI processors provide all audio decoding and processing functions, communications protocol processing, and all control processing for the A5's driver interface. "Blackfin in conjunction with additional ADI technologies gave us competitive and distinguishing features that differentiate our new vehicle, enhance our brand positioning, and reflect our relentless pursuit of the perfect driving experience," Peter Kohlschmidt, director of wireless, acoustics, and connectivity for Audi, said in a statement. The Blackfin ADSP-BF539 and ADSP-BF532 processors power the DAB radio and MP3-compatible 6-way CD changer. Another Blackfin ADSP-BF532 processor drives the Music Interface, which integrates portable media players like the Apple iPod for dashboard display and steering-wheel control. An optional Bang & Olufsen (B&O) surround sound amplifier that delivers the utmost in high fidelity is based on an ADI SHARC ADSP-21362 processor. Other analog signal-processing components are used in the new car, including: · ADI's ADM6319, a supervisory circuit that monitors power supply voltage levels and code execution integrity in microprocessor-based systems · The AD7478 8-bit, low-power, (SAR) successive approximation analog-to-digital converter (ADC) · The AD9280 single-supply, 8-bit, 32 MSPS ADC · The ADuC7032 precision battery monitor sensor, a complete system solution for battery monitoring in 12V automotive applications. "By focusing on the entire driving experience, Audi is establishing a new kind of competitive advantage that can only be achieved through visionary adoption of advanced electronics devices,” Mark Gill, director of automotive infotainment products for ADI, said in a statement. "ADI’s Blackfin and SHARC processors are ideal enablers of this kind of visionary thinking, helping car makers leverage the added value of advanced audio, video, navigation and display functionality."
