NXP Integrates Cadence Tensilica HiFi 5 DSPs for Enhanced Audio Processing

Automotive technology is advancing rapidly, and with it comes the need for sophisticated audio processing capabilities to support a wide range of applications. NXP, a leading provider of automotive solutions, has partnered with Cadence to integrate their high-performing Tensilica HiFi 5 DSPs into the SAF9xxx series. This collaboration aims to address the diverse demands of next-generation vehicles, particularly in the realm of artificial intelligence and machine learning (AI/ML) applications.

By incorporating Cadence's HiFi 5 DSP cores, NXP is able to bring robust AI/ML-based audio capabilities to mid-tier and high-end automobiles. This integration significantly enhances the driving experience by creating richer and more immersive in-cabin audio environments. Larry Przywara, senior product marketing group director at Cadence, highlighted the success of this partnership, stating that millions of vehicles today benefit from the high-quality audio delivered through their collaboration.

The Tensilica HiFi 5 DSPs excel in merging AI/ML processing with traditional digital signal processing, allowing for high-performance levels while maintaining energy efficiency. This capability enables a multitude of compute-hungry applications to run concurrently, making the HiFi 5 DSPs ideal for automotive head units with limited space for heat sinks. The low power profile of these DSPs further enhances their suitability for automotive applications.

John van den Braak, senior vice president at NXP, emphasized the importance of AI/ML-based algorithms in next-generation automotive infotainment systems. By integrating two Tensilica HiFi 5 DSPs with neural network engines, NXP is poised to efficiently run future data-driven algorithms that cater to evolving consumer demands. The availability of HiFi 5 DSP-optimized software packages from Cadence's ecosystem of partners further streamlines automotive development cycles.

Safety is a top priority in automotive applications, and the Tensilica HiFi 5 DSPs are Functional Safety (FuSa) certified to meet these stringent requirements. This certification ensures that the DSPs can be utilized in safety-critical scenarios, providing manufacturers and consumers with peace of mind. NXP's integration of these certified DSPs in the SAF9xxx series signals a transformative shift in the automotive infotainment industry, promising AI/ML-enhanced audio experiences that align with modern consumer expectations.
