Classic or Adaptive AUTOSAR:
Why not both?
The Evolution of AUTOSAR
AUTOSAR (AUTomotive Open System ARchitecture) is an international partnership of vehicle manufacturers and suppliers that officiate the standardization of basic system functions, functional interfaces, and architecture of automotive electronic control units (ECUs). AUTOSAR defines two platform standard specifications—Classic and Adaptive.
Classic Platform standards were first published in 2004. The standards support the designs of software stacks assumed to run on microcontrollers within the context of an intranet connected ECU vehicle LANs. The specification is generally limited to support the application development needs of controlling vehicle subsystems over CAN, LIN, and internal Ethernet buses.
Adaptive Platform is a next generation specification published in 2018. Adaptive Platform supports advances in hardware, and modern software platform components such as POSIX® Operating Systems to accommodate designs that require internet connected ECUs to provide end-user capabilities such as infotainment cloud applications, vehicle to road infrastructure ADAS, and remote software updates.
Rich Functionality & Comprehensibility

Valid concerns emerge when developers face challenging ECU projects that must satisfy adaptive requirements but need mathematical assurances that vital tasks are protected from potential side effects of complex abstraction layers such as network stacks and concurrent filesystems.


Together with Robert Bosch GmbH, Lynx and ETAS provide a safe, secure, and adaptable foundation for the ETAS RTA-VRTE platform software solution. RTA-VRTE incorporates the AUTOSAR Adaptive standard and supports the next generation of cross-domain and vehicle computer ECUs being introduced into upcoming vehicles.

Under this partnership, ETAS includes the foundational processor partitioning system of Lynx MOSA.icTM to its automotive software stack to significantly enhance ECU and vehicle computer security as well as safe system separation of domain controllers and vehicle computer ECUs.

Through Lynx MOSA.icTM, ETAS supports the RTA-BSW AUTOSAR solution, the RTA-VRTE AUTOSAR Adaptive platform, and the ESCRYPT embedded security solution, which run within the lightweight isolated rooms. This combination forms a complete and highly adaptable software platform designed to address real time automotive use-cases requiring the highest levels of safety and security.

Build Freely

Lynx introduces  a rich set of options for design teams to leverage both worlds of Classic and Adaptive standards without having to compromise on real-time performance and design comprehensibility.  Develop bare-metal, POSIX® RTOS, or Embedded Linux guests.  Rapidly integrate partner-, competitor-, or proprietary components together to form modern or traditional automotive architectures.

Consolidate with Confidence

Deterministic behavior is sacrosanct for safe automotive designs.  For consolidated domain controllers—where tasks of different complexity levels are running in parallel—comprehensibility is essential to manage the growing complexity of ECUs microprocessors and software abstraction layers. Lynx MOSA.icTM provides an elegant model for managing concurrency through its distributed control plane and modular message based architecture to ensure inherently complex automotive designs scale comprehensibly.  Harness the power of modern multi-core SoCs with transparent evidence of safety, security, and hard real-time execution.

Reuse Components

The Automotive Industry pioneered  modular integration for assembly and production.  Lynx is pioneering advances in software development through modular design. Each software component within Lynx MOSA.icTM is an independent module that can be efficiently integrated into a next-generation or legacy projects— similar to reusing an ECU in a new vehicle design. 

Leverage Lynx MOSA.icTM  to re-use existing microcontroller code written to the Classic AUTOSAR standard and to port existing ISO 26262 codebases into secure isolated partitions running safely and securely next to general purpose OSs.  Unlock rapid development through system module integration, boosting reliability by isolating faults and drastically lowering lifetime costs through the reuse of legacy components for future designs.
