Multicore micro-controller

Usage in advanced driver-assistance systems

Published 2017-10-12

Nvidia, supplier of ADAS electronic control units and ECUs for automated driving, has chosen the Aurix processors by Infineon. They are used as a safety compute element and vehicle interface for the Drive PX 2 AI hardware platform.

Nvidia’s autonomous vehicle computing platforms are integrated in various advanced driver-assistance systems (ADAS) and initial Level-3 autonomous driving cars to reach production.

Ritesh Tyagi (Infineon): “We make autonomous driving safe and reliable, and the collaboration with Nvidia is a great example of one such important initiative. To support this effort, we have established the Innovation Center in Silicon Valley to work closely with technology partners and mobility disruptor customers including traditional car manufacturers and their system suppliers.” (Photo: Infineon)

The Aurix TC2xx multicore micro-controllers feature advanced hardware capabilities for functional safety compliant to Asil-D as specified in ISO 26062. They are integrated into the platform as safety controllers for ADAS and autonomous driving (AD) systems now deployed worldwide. Key features of the MCUs relevant to bringing ADAS and AD to the street include lock-step cores, redundant peripherals, integrated monitoring systems, and up to 1800 DMIPS of real-time performance based on the Tricore multicore architecture.

The micro-controllers provide multiple CAN FD channels and other IVN (in-vehicle network) interfaces. The collaboration of Infineon and Nvida enables users of the Drive PX platform to access the Aurix capabilities through an Autosar-compliant software stack. Thus, higher-level application layers can easily be adapted, thereby reducing development time by 20 percent to 40 percent compared to traditional platforms.

Infineon is now expanding the Aurix products with the next generation, the TC3xx family. It will offer higher integration, and real-time performance that is three times higher than what is available today. This allows system suppliers to migrate to the TC3xx family by leveraging the development investment in the Aurix TC2xx family. The MCU families will fuel autonomous driving applications in the coming years, claims the German chipmaker.
