NXP Semiconductors has developed a digital signal processing (DSP) chip for AI-based audio in software defined vehicles (SDVs) and software defined radio (SDR).

The NXP SAF9xxx uses the latest generation Tensilica 5 DSP core from Cadence combined with dedicated neural-network engines for self-learning audio and speech applications.

The SAF9xxx family also has a software-defined radio option with up to five integrated tuners, covering all major global broadcast radio use cases, including DAB, HD-Radio, DRM, CDR, and AM/FM. This one chip device supports audio and radio applications with scalability.

 Next generation Tensilica processor targets embedded AI

Audio performance is a major differentiator for automotive infotainment, providing OEMs with new ways to make mid-range and high-end vehicles stand out. The machine learning capabilities with neural network integration opens up the ability to recognize and distinguish the driver from passengers by identifying their voice pitches and accents. Emergency vehicle sirens can be detected with machine learning algorithms, and used to provide drivers with audiovisual information about the location and movement of an emergency vehicle.

The SAF9xxx family is optimized for low-latency audio applications, enabling real-time active cancellations of engine, road, wind, and tire noise.  Gigahertz-DSP performance is complemented by a large, fast-access onboard memory and a comprehensive set of analogue and digital I/Os that support demanding audio features. 

“The NXP SAF9xxx DSP is a ready-made infotainment solution. Designed with AI/ML processing capability in mind, it provides more functionality, better performance, and more features to support the demanding audio and radio requirements of both current and future software-defined vehicles. And its scalable architecture makes it simpler and more affordable for OEMs to deploy in their vehicle design,” said John van den Braak, Senior Vice President and General Manager for Audio Systems at NXP. 

A large audio IP partner ecosystem is available with audio software and algorithms.
