The automotive industry is on the brink of a transformative era powered by intelligence, safety, and seamless user experiences. Integrating digital signal processing and artificial intelligence (AI) transforms vehicle intelligence. It enhances user experiences, crucial in next-generation features such as advanced driver-assistance systems (ADAS), in-cabin sensing, infotainment, and overall system design. Cadence is essential in supporting this through its advanced AI-driven digital signal processors (DSPs). These innovations make vehicles safer, smarter, and more engaging.

At CadenceLive Silicon Valley 2025, Amit Kumar, Director of Product Management and Marketing, emphasized how Cadence’s specialized DSPs and AI intellectual property (IP) cores are key to developing future automotive systems. This blog is an excerpt from that presentation. It discusses how AI-powered DSPs foster innovation in the automotive industry and how Cadence enables this modernization.

The Impact of AI-Powered DSP Technology on Automotive Innovation

The automotive industry is rapidly evolving in response to the growing demands for greater safety, autonomy, and enhanced user experience. Modern vehicles are no longer just modes of transport—they are intelligent, connected platforms. The shift towards an AI-driven future redefines every aspect of automotive systems, chiefly through ADAS, in-cabin sensing, and immersive audio experience.

ADAS and Autonomy

ADAS has progressed from enhancing driver safety to enabling fully autonomous driving capabilities. This evolution involves:

• Perception sensors such as cameras, radars, LiDAR, and thermal systems
• Sophisticated signal processing for object detection, mapping, and trajectory planning. DSP cores in these systems ensure real-time data processing with minimal latency and low power consumption
• Integration of AI algorithms, such as convolutional neural networks (CNNs), recurrent neural networks (RNNs), and vision transformers, enhances perception and decision-making accuracy

The progression from Level 0 to Level 5 autonomy relies heavily on the seamless operation of these technologies. Here, DSP cores play a pivotal role, offering real-time processing at high computational speeds and ensuring the smooth functioning of ADAS/AD.

In-Cabin Sensing for Safety and Comfort

Modern vehicles are designed to be as intuitive and passenger-centered as possible. DSP-driven in-cabin sensing systems employ AI technologies to:

• Monitor child presence detection (CPD) and driver conditions (DMS)
• Perform vital signs monitoring to ensure emergency preparedness
• Improve situational safety by integrating data from a spectrum of sensors, including vision and radar modalities

Mandates by organizations like Euro NCAP and the demand for enhancing user experience are pushing car manufacturers to adopt in-cabin sensing solutions powered by AI and DSP technologies.

Infotainment and Immersive Audio Experiences

A significant aspect of vehicle user experience is connected to how well in-cabin entertainment functions. DSP cores are renovating this area by enabling:

• AI-enhanced audio processing to reduce noise, improve clarity, and create immersive soundscapes

• Zonal audio technologies like "audio bubbles" to localize sound experiences for individual passengers
• AI-based acoustic enhancements include engine sound augmentation and tailored noise cancellation

These new features need to process data from multiple sensors, integrate AI for inferencing and real-time decision-making, and use advanced audio DSPs for an immersive audio experience.
