The Tata Elxsi eCockpit solution addresses future vehicle cockpit requirements supporting infotainment, instrument cluster, HUD and ADAS functionalities on a single SoC while maintaining high levels of safety, security and performance.
Demonstration pairs are on show at this week's Embedded World, in Nuremberg, and include Tata’s eCockpit with the Green Hills ASIL-certified INTEGRITY RTOS and its Multivisor secure virtualization architecture that safely and securely consolidates mixed-criticality applications on a single, automotive-grade Renesas R-Car H3 processor.
INTEGRITY Multivisor runs Linux and Android in independent, secure virtualized partitions. Tata Elxsi Infotainment is based on Automotive Android and the instrument cluster is running on Linux. Infotainment features are shown through a 2D/3D custom HMI on Automotive Android. V2X features are also integrated and displayed on the instrument cluster as warning messages. Linux guest OS is partitioned using Linux Containers to accommodate sub domains like ADAS. A separate Linux Container runs Tata Elxsi’s Sensor Fusion ADAS IP over Tata Elxsi’s own Adaptive AUTOSAR. Complete vehicle interface functionality is based on Tata Elxsi’s own classic AUTOSAR 4.3.
The INTEGRITY RTOS microkernel architecture is designed for critical embedded systems demanding proven separation, security, and real-time determinism. Its separation architecture will help software teams to safely and securely partition software running at different levels of criticality on the Renesas R-Car H3 processor while guaranteeing applications the system resources required for their proper execution.
This enables safe and secure execution of applications running graphics and multimedia while at the same time ensuring the safe operation of critical functions, such as the tell-tale status and warning lights.
“Tata Elxsi’s eCockpit, combined with Green Hills INTEGRITY Multivisor, is platform agnostic and it provides automotive makers with a complete single-ECU solution for instrument cluster, infotainment and ADAS functionalities that delivers real-time performance on a single multicore automotive-grade microprocessor,” said Dan Mender, vice-president business development, Green Hills Software. “Tata Elxsi’s software development and system integration for cockpit systems is driving the industry and we will continue to work together for providing safe and secure systems while supporting the cost and space reduction demands that are driving the trend of ECU consolidation.”
