Leading the Embedded World

A Global Leader in AUTOSAR

As vehicle electronics evolve and mature to become sophisticated, high-performance compute platforms that can handle a dynamic, configurable and upgradable workload, the role AUTOSAR plays in the design of next-generation advanced vehicle electronics has also evolved with the availability of AUTOSAR Adaptive solutions as defined by the AUTOSAR Consortium.

In order to properly design, debug and deploy these next-generation domain controllers and high performance compute platforms, Green Hills builds on its 25+ years of successful experience in automotive electronics development and 15+ years of participation and support of the AUTOSAR Consortium and leading AUTOSAR solutions providers to enable global automotive OEM’s and Tier 1’s with the ability to realize next-generation vehicle architectures based on high performance, service-oriented communications in a manner that allows the designer to control the complexity, safety and security of the platform while supporting the scalability and upgradability required to achieve their design goals.

AUTOSAR is crticical for managing complexity of ECUs in vehicles

As new features and expanding demands for safety, security, and efficiency challenge traditional vehicle electronic architectures, the AUTOSAR software development standard is critical for managing the growing complexity of ECUs in today's vehicles.

Simple, scalable high performance AUTOSAR Classic and Adaptive support

Future vehicle electronics will rely on the next generation of advanced, high performance multicore microprocessors. While this advanced processor capability will support the compute advancements required for the next generation of performance needs and service oriented architecture capabilities that may rely on AUTOSAR Adaptive, there is also a need to support legacy AUTOSAR Classic system services safely and securely integrated into these new architectures.

Since 2005, Green Hills has been supporting global customer development, debug and deployment of AUTOSAR Classic vehicle electronics by providing the industry's most recognized ISO 26262 safety certified development tools and C/C++ run time libraries—the MULTI IDE.

In addition to the MULTI AUTOSAR-aware advanced safety-certified development environment, Green Hills also supports the ability to host and execute vendor-specific AUTOSAR Classic run-time environments natively on its INTEGRITY real-time separation kernel—without requiring virtualization support. With these AUTOSAR vendor-specific integrations, Green Hills enables:

  • AUTOSAR Classic development and debugging on standalone MCU’s/Safety Islands (e.g., Cortex-R, M, TriCore, RH8xx)
  • AUTOSAR Classic development, hosting and debugging integrated and executing in a native INTEGRITY virtual address space/container combined with other system services running on the high-performance multicore processor (e.g. Cortex-A, IA)

With this capability to run AUTOSAR Classic natively on INTEGRITY, Green Hills offers the most scalable, configurable AUTOSAR architecture to host AUTOSAR Classic assets and services that support AUTOSAR vendor-independent execution and mixed ASIL certification level integration. This means that the Green Hills platform gives customers the flexibility to incorporate and run their own AUTOSAR Classic asset, an OEM’s AUTOSAR Classic asset or a third-party asset without compromising the performance, safety architecture or security in the platform.

In addition to its decades of AUTOSAR Classic experience, Green Hills has been elevated to a Premium Partner of the AUTOSAR alliance and has been active in a number of AUTOSAR Adaptive working groups. In addition to its working group efforts, Green Hills has been collaborating with the leading AUTOSAR Adaptive solutions providers to integrate and host these vendors’ AUTOSAR Adaptive services natively on safe and secure Green Hills INTEGRITY real-time separation kernel.

For AUTOSAR Adaptive, Green Hills leverages the INTEGRITY RTOS certified separation architecture and policies to natively run AUTOSAR Adaptive, as compared to other vendors that must rely on less secure virtualization for system separation.

As a result, customers eliminate the significant complexities, performance overhead, security impacts and development and debug challenges that come with using a type-1 hypervisor platform approach for supporting AUTOSAR Adaptive in vehicle electronics designs.

Advanced AUTOSAR-aware multicore development

With the growing complexity of vehicle electronics running multiple instances of AUTOSAR Classic and/or Adaptive, multiple operating systems and multiple software assets from OEMs, Tier 1s, Tier 2s and open source, advanced debug, performance optimization, system integration, test and validation capabilities are needed in order to realize these new system capabilities in a way and timeframe required.

Green Hills has developed and optimized the next generation of tools and techniques for customers who are developing, debugging, optimizing, integrating, testing and delivering complex embedded solutions. Relying on its mature MULTI tools solutions and capabilities, Green Hills is delivering the most advanced debug tools as:

  • OS agnostic
  • Processor agnostic
  • Trace Log agnostic
  • Highly optimized for minimal system intrusion
  • Designed for all phases of a program:
    • Individual developer
    • Bench integration
    • Test and validation
    • Prototype platform integration
    • Platform deployment

These advanced tools capabilities are designed for globally distributed platform development, integration, test and validation.

With this enablement of time-synchronized system level debug and optimization, the ability to analyze complete system behavior can be achieved in a manner independent of site, vendor, processor and application.

To make this all possible, Green Hills relies on its portfolio of proven products, techniques and know-how to work with customer development teams and customer programs to incorporate these assets and debugging knowledge. At a high level, these assets consists of:

  • High-performance JTAG Trace Hardware Probes
  • Low-latency system logging techniques
  • Advanced time-synchronized system viewing that is OS and trace log agnostic
  • Step forward and back in time debugging

Safety and security through proven separation

The INTEGRITY RTOS andMultivisor secure virtualization service isolates critical system applications, services and security tasks from other tasks – consisting of guest operating systems, and AUTOSAR applications, providing a secure, safe, and scalable architecture ideal for mixed-criticality ASIL-certified systems.

INTEGRITY Multivisor partitioned architecture for AUTOSAR systems

The INTEGRITY RTOS certified separation kernel isolates critical systems servicesfrom each other and from guest operating systems. Because both Classic and Adaptive AUTOSAR systems can be run in their own partitions, systems designers have more flexibility to build scalable systems. Click for a larger view.

For future domain controllers, gateways, zonal compute nodes and high-performance compute clusters, the foundation for hosting, executing and managing this run-time software architecture must be safe, secure and scalable. Green Hills Automotive Platforms are built on INTEGRITY real-time operating system (RTOS) technology, certified at the world's highest safety and security levels. INTEGRITY’s certified separation kernel isolates critical system services from each other and from guest operating systems such as Linux and Android, running on the same core or multiple cores. In addition, both AUTOSAR Classic and Adaptive systems and their applications can be run in their own virtual memory partitions, giving system designers more flexibility to build scalable systems.
