NXP Advances AI Audio Processing with SAF9xxx Audio DSPs

NXP Semiconductors is improving AI audio capabilities in automotive infotainment and marking a significant improvement in automotive audio processing technology in general with the latest SAF9xxx family of audio DSPs. Utilizing Cadence’s latest generation high-performance Tensilica HiFi 5 DSPs, combined with dedicated neural-network engines, the SAF9xxx audio DSPs enable efficient implementation of next-generation, high-quality, self-learning audio and speech applications.

Skyworks Solutions introduced the Si469xx family of automotive digital radio coprocessors for in-vehicle infotainment (IVI) systems. With its combination of integration, flexibility and low cost, the Si469xx family of coprocessors is optimized to operate with Skyworks’ Si479xx Hybrid Software Defined Radio (SDR) Tuners. The new Si469xx product family can demodulate and decode up to four digital radio channels supporting HD Radio, DAB/DAB+, DRM (for AM and FM), and CDR, providing high performance and unmatched scalability.

According to a recent study by Edison Research, Americans already spend more time listening to audio sources on mobile devices than they do from radio receivers. This is the first time that phones surpass the time spent listening to traditional radio, revealing that mobile phones continue "chomping" audio shares. And more worryingly for traditional broadcast radio, this is happening even in the car.

During the Welcome Session at NAB Show 2023, NAB President and CEO Curtis LeGeyt discussed a wide range of topics, including the importance of keeping radio in the car dashboard, and specifically defend AM radio and its importance for emergency services and remote areas. LeGeyt also promoted the importance of local broadcasting, and the work of local journalists, at a moment of intense competition, technological evolution and innovation.

Silicon Labs has introduced new hybrid software-defined radio (SDR) tuners, expanding its portfolio to meet the growing need of automotive radio manufacturers to support all global digital radio standards with a common platform. In addition to introducing new DRM-capable tuners, Silicon Labs is enhancing its Si4790x/1x/5x/6x automotive tuners with unique “SDR-friendly” technology, effectively transforming these devices into hybrid SDR tuners.

CSR announced two new automotive infotainment products at TU Automotive Detroit 2015. The new CSRatlas7 platform combines hardware and software to boost simplicity, lower costs, and speed time-to-market. CSR also has entered the car radio tuner front-end market with tuneX, a cost-effective software-defined radio (SDR) solution for the in-vehicle environment.
