Today Infotainment systems are much more than a simple car radio and provide the central human-machine interface (HMI) to a variety of features like navigation, entertainment, communication, display, 3D instrument cluster, and ADAS functions. They also facilitate over-the-air software updates, which allow the customer to purchase new features as they become available during the lifecycle of the car. Hence the integrated digital cockpit greatly defines the overall user experience of the car.
Cadence® Tensilica® HiFi DSPs for audio, voice, and speech and their strong ecosystem partners, including Dolby and DTS, allow chip manufacturers to design feature-rich infotainment SoCs, with the latest audio, voice, speech recognition, and voice enhancement software.

Graphical Audio Design and Tuning Tool
Audio Weaver™ from DSP Concepts is an innovative graphical design environment for developing and tuning optimized embedded audio software such as the Tensilica HiFi DSP. Development teams can create applications that realize their desired sound quality up to 10X faster than traditional development approaches by re-using pre-built, highly optimized audio processing modules. The real-time tuning capabilities of the Audio Weaver tool give automotive audio engineers complete control of their audio signal chain.
Navigation Systems with Integrated ADAS
The Tensilica Vision DSP family is optimized to run compute-intensive vision algorithms and neural networks for automotive applications such as object detection, traffic sign recognition, augmented reality navigation, driver monitoring, fog clearance, and night vision systems. Cadence has a rich set of software partners for vision applications.
- ADAS, imaging, and computer vision
- Image enhancement
- In-car occupancy detection
- Face authentication
- Pedestrian detection
- Convolutional neural network (CNN) deep learning
Wi-Fi and Bluetooth Communications, LTE and 5G Radios, Radar, and Lidar
The Tensilica ConnX family of enhanced DSPs establishes a new standard in high-performance, low-power digital signal processing specifically designed for the next-generation radar, lidar, and communication systems.
Whether it’s a product targeting a 5G communications microcell, LTE Advanced, Wi-Fi access point, Car2X, high-resolution imaging radar sensor, or a lower-cost solid-state lidar, they all benefit from the flexibility of a software-based solution as these markets develop and mature.
Interface and Memory IP
Cadence’s complete portfolio of interface and memory IP provides all the links from the user interface to the internal electronics of the infotainment system. Our interface IP solutions provide controllers/PHYs for cameras connecting via a MIPI interface, charging connectors through a USB interface, updating maps through an SD interface, [verb-ing] to high-definition displays, playing music through a SATA interface, or communicating via high-speed Automotive Ethernet with other systems. Internally, our widely used memory IP PHY and controllers keep data streaming throughout the system.
