Infineon and Nvidia co-operate for safe, automated driving
Infineon Technologies’ Aurix microcontroller family is used as a critical safety computer element and vehicle interface for Nvidia’s Drive PX 2 artificial intelligence (AI) car computing platform. Nvidia says its autonomous vehicle computing platforms are integrated in various ADAS for new vehicles and initial Level 3 autonomous driving cars to reach production. The Aurix multi-core microcontrollers feature advanced hardware capabilities for functional safety.
At its OktoberTech 2017 Technology Forum, Infineon demonstrated how the Aurix microcontrollers help the Nvidia Drive PX platform meet the highest possible functional safety standard (ISO 26262 ASIL-D) for self-driving systems. Key features include lock-step cores, redundant peripherals, integrated monitoring systems and up to 1,800 DMIPS of real-time performance based on the Infineon TriCore multi-core architecture.
The Aurix TC2xx family provides critical functionality including power-up sequence management and monitoring of warning signals for the self-driving platform. The Aurix microcontrollers also act as the decision maker, voting for specific tasks that must comply with ASIL-D safety standards. They also act as the main in-vehicle interface for multiple network communication channels such as CAN, Ethernet, FlexRay and LIN.
The collaboration of Infineon and NVIDIA enables users of the Drive PX platform to access the Aurix capabilities through an AutoSar-compliant software stack. Higher-level application layers can be adapted to reduce development time by 20 to 40 per cent, claims Infineon, compared to traditional platforms.
Infineon has 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.
Infineon is expanding the Aurix family with the next generation, 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 easily migrate to the TC3xx family by leveraging the Aurix TC2xx family.
The Aurix multi-core TC2xx and TC3xx microcontrollers are expected to be widely deployed in data fusion architectures worldwide.
