Green Hills Software and Tata Elxsi Demonstrate Highly Integrated Automotive Cockpit Solutions

According to foreign media reports, Green Hills Software has partnered with Tata Elxsi to launch the next generation of software-driven, highly integrated automotive cockpit solutions. Green Hills Software is a leading supplier of embedded security solutions, while Tata Elxsi is a design and technology service provider.

The two companies will demonstrate the first collaborative effort at embedded world 2020 – Tata Elxsi’s Cockpit solution, which runs on Green Hills Software’s Secure Integrity, real-time operating system (RTOS) and Integrity Multivisor secure virtualization architecture.

Tata Elxsi said its eCockpit solution meets all the needs of a fully functional automotive cockpit, supporting infotainment, instrument cluster, HUD (head-up display) and ADAS functions on a single system-on-chip (SoC), while also providing the highest levels of safety and performance.

The demonstration combines Tata’s eCockpit with Green Hills’ Automotive Safety Integrity Level-compliant RTOS and its Multivisor secure virtualization architecture to safely consolidate mixed-criticality applications on a single automotive-grade Renesas R-Car H3 processor.

Integrity Multivisor uses Linux and Android in independent and secure virtualized partitions, and the Tata Elxsi infotainment system is built on the automotive Android system, and its instrument cluster runs in the Linus system. The infotainment system displays functions through a 2D/3D customized HMI (human-machine interface) of the Android automotive system. The Linux Guest operating system is partitioned using the containerization tool Linux Container to accommodate subdomains such as ADAS. A separate Linux Container runs its sensor fusion ADAS IP on Tata Elxsi's adaptive AUTOSAR. The complete vehicle interface function is built on Tata Elxsi's classic AUTOSAR 4.3.

The two companies said that the Integrity RTOS microkernel architecture is designed for critical embedded systems that require reliable, secure, and real-time determinism. Its separation architecture can help software teams safely partition software of different criticalities running on the Renesas R-Car H3 processor while ensuring the system resources required for the correct execution of applications, enabling applications running graphics and multimedia to execute safely and reliably while ensuring that critical functions such as alarm status and warning lights can run safely.
