Tata Elxsi’s eCockpit solution which runs on Green Hills Software’s safe and secure INTEGRITY Real Time Operating System (RTOS) and INTEGRITY Multivisor secure virtualization addresses all the requirements of a full feature vehicle cockpit, supporting infotainment, instrument cluster, HUD (Heads Up Display) and ADAS (Advanced Driver Assistance Systems) functionalities on a single SoC while maintaining the highest levels of safety, security and performance.
The demonstration pairs Tata’s eCockpit with the Green Hills ASIL-certified INTEGRITY RTOS and its Multivisor secure virtualization architecture to safely and securely consolidate 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 AUTOSAR4.3.
The INTEGRITY RTOS microkernel architecture is designed for critical embedded systems demanding proven separation, security, and real-time determinism. Its separation architecture helps 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 telltale 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.”
“Green Hills Software’s years of production program experience in mixed-criticality, safety-certified system design, coupled with their advanced MULTI toolchain, significantly simplified our integration effort and reduced development time without requiring compromises in performance, safety or security in the system,” said Nitin Pai, Chief Marketing Officer & Chief Strategy Officer, Tata Elxsi. “Our collaboration with Green Hills on this type of mixed-criticality platform consolidation allows us to provide customers with truly unique value propositions as the automotive industry looks to our joint, proven, production-ready capabilities.”
MOBILITY ENGINEERING SPOKE TO MR. SHAJU S – GENERAL MANAGER & HEAD TRANSPORTATION BUSINESS UNIT AT TATA ELXSI:
What are the different developmental inputs that went in, separately from Tata Elxsi and Green Hills Software (GHS) towards the eCockpit solution?
Tata Elxsi was responsible for defining the eCockpit architecture and virtualization partitioning was based on GHS hypervisor. We developed the complete eCockpit solution, which includes Android P based IVI & Linux based Cluster. eCockpit solution Integrated Tata Elxsi’s Classic AUTOSAR, Adaptive AUTOSAR, Sensor Fusion algorithm IPs. GHS has provided hypervisor for RCarH3 with required support for Android & Linux. GHS also supported the Integrity safe and secure OS to handle functional safety requirements.
What are the technical parameters required at the OEM’s end for integrating the solution in their automobiles?
OEM needs to define feature scope, domains to be integrated, safety, performance, certification & BOM cost requirements. Theses inputs will decide SoC & other H/W peripherals to be used. Tata Elxsi works on developing and integrating this eCockpit solution as per OEM requirements.
What are the specific benefits to the driver of the vehicle?
Architecture is flexible and modular to accommodate multi-model HMI with all usability considerations for OEM. Minimizing distraction is the major benefit for the end user since some ofthe important alerts like call, music track, surround view camera view, emergency vehicle approaching etc. can be shown from the digital cluster that allows the driver not to take his eyes away.
What types of vehicles (passenger, CV, HD etc.) are ideally suited for the solution to be used?
Architecture can be adapted to all types of vehicles. Safety requirements and features would be different as per vehicle types.
Are upgrades and updates Internet-dependent?
USB and OTA upgrades both will be supported by this architecture.
What is Greenhills LM?
The Greenhills License Manager (or GHS LM) is a license manager that is mandatory for all GHS software running on a host machine (as opposed to their embedded products for IoT and other devices). There are 4 available license models:-
- Floating License. The license keys are installed on a network license server
- Named-user. The license keys are installed on the network license server, but only the named user or the administrator can access the license.
- Computer-locked. The license key is installed on a specific machine
- Dongle-locked. The rights to using the license are stored in a device, such as a dongle. Machines which are cleared to use the software must also have a license key installed.
There is also a “Legacy” license available for very old software versions.
Usb Modem Drivers
OpenLM provides the following functionality for monitoring LM-X Licenses:-
- Denials ReportingNo
- Report resolutionBy Minute
- Borrowed License reportingNo
- Expiration Date reportingYes
- Multiple Server Redundancy SupportNo
- Token License SupportNo
Greenhills GHS is only one of over 25 license managers that OpenLM can manage. Check the list.
Parsing Green Hills logs
OpenLM has added the Green Hills license manager to its portfolio of monitored license servers in version 3.2.
Green Hills log files are also interpreted in the OpenLM “All License Parser” online tool.

Who is Greenhills?
Greenhills Software (GHS) was founded in 1982 in California, and specializes in real-time operating solutions (RTOS) and embedded security systems for protection of IoT devices. Their flagship product is the Integrity RTOS, which holds the highest certification by the NSA of EAL 6+ High Robustness, which certifies it for the protection of critical resources against cyberattack, in industries such as aerospace, where most manufacturers (including Airbus, Boeing, Lockheed Martin) use it for their avionics.
They have also developed a Device Lifecycle Management (DLM) system to help manage devices throughout their life. Their embedded software is supplied with an embedded license. Where GHS software is running on a host machine, customers a required to install the GHS License Manager.
