Leading the Embedded World

Overview

Automakers and their electronics suppliers face a new world of in-vehicle infotainment (IVI) opportunities and challenges. Consumers increasingly want their cars to be a plug-and-play “entertainment system on wheels” offering the latest multimedia, gaming, location awareness, communications, and personalized services—all of the features they already enjoy on their smart phones, tablets, and other mobile devices. Automakers are also eyeing app stores, both open source and proprietary, for brand differentiation and as new revenue streams.

More features — more software complexity

In-vehicle infotainment systems today integrate an ever-growing array of entertainment and informational features. As a result, software size and complexity is exploding. Despite so much software content, IVI systems must still meet the required automotive robustness within traditional automotive cost, safety, security, size, weight, and power budgets.

The Green Hills In-Vehicle Infotainment Platform is based on Green Hills Multivisor virtualization solution, a service of the safety- and security-certified INTEGRITY real-time operating system. Companies that select the Green Hills In-Vehicle Infotainment Platform as the foundation for their next-generation IVI system gain significant advantages over their competition through benefits that include reduced development time and cost, widest breadth of scalability, higher system reliability, and advanced system security.

Consumers increasingly want the infotainment systems in their cars to be as plug-and-play as their phones—offering the latest communications, gaming, navigation, and personal services.

Safe, secure, and scalable

In-vehicle infotainment architecture must be safe, secure and reliable. The Green Hills Platform for In-Vehicle Infotainment is built on INTEGRITY real-time operating system (RTOS) technology, certified at the world’s highest safety and security levels enabling IVI developers to develop and deploy with confidence.

The INTEGRITY RTOS’ memory protection, microkernel architecture, and virtual device driver paradigm ensure that the core kernel is impervious to the software bugs that inevitably surface in a sophisticated infotainment system. Beyond memory protection, however, INTEGRITY guarantees the necessary memory and CPU resources that each application needs to operate. A problem in a less critical subsystem cannot affect the operation of the more critical subsystem. The same partitioning and resource guarantee capabilities protect the infotainment applications from Internet-borne worms or viruses. Even if a virus were to get into the system, existing applications cannot be starved of memory or CPU time. Similarly, a bug or design flaw in a less critical component cannot affect another protected component.

Green Hills INTEGRITY RTOS

The INTEGRITY architecture supports multiple protected virtual address spaces, each of which can contain multiple application tasks.

The INTEGRITY RTOS’ worst case interrupt latency is known, short, and bounded. As a result, real-time management of audio, video and communications channels—such as CAN—are deterministic, maximizing the passenger infotainment experience, while delivering the highest levels of system reliability.

Immediate response with uncompromised performance

Car owners expect their infotainment system to be ready for use immediately after they press the “on” button. INTEGRITY boots “instant-on,” enabling time-critical functions such as a rear-view camera or door chimes to be up and working immediately.

Unlike other memory-protected operating systems, INTEGRITY never sacrifices real-time performance for security or safety. INTEGRITY boots and executes the most critical system tasks in milliseconds, while delivering guaranteed deterministic response, and hard real-time performance in a separation kernel architecture to support safe, secure execution of mixed-criticality applications.

Embedded virtualization for maximum flexibility

IVI systems must be highly scalable and must meet a broad range of market requirements, so IVI developers need a flexible software architecture that scales easily.

INTEGRITY Multivisor is secure virtualization based on INTEGRITY RTOS technology, and provides guaranteed partitioning for safe hosting of guest operating systems, real-time applications and peripheral driver software all running on complex multicore processors with or without hardware-assisted virtualization support. Systems developed today can be upgraded or otherwise enhanced for years to come.

For example, a simple and inexpensive IVI system for an economy vehicle, for example, might include a small monochrome display, an aux port, and hands-free Bluetooth. Standalone INTEGRITY RTOS meets these requirements. A midrange system could demand a larger display with embedded navigation, Internet radio, location-based services and voice commands. It would also display basic vehicle dynamics available on the CAN bus. Here, INTEGRITY Multivisor enables a guest operating system such as Linux or Android plus a separate and secure partition running a CAN bus application through an OSEK or AUTOSAR interface.

As for the luxury IVI system, the developer’s imagination is the limit. Another guest operating system and its app store can be added; more real-time tasks and secure communication to the cloud or other connected cars. The Green Hills Platform for In-Vehicle Infotainment offers a solid foundation for developers to satisfy IVI requirements for every model in an automaker’s line.

Simple and scalable high-performance AUTOSAR support

As new features and demands for safety, security, and efficiency challenge traditional vehicle electronic architectures, the AUTOSAR software framework plays a key role in managing the growing complexity of ECUs and their software. As a Premium Partner of AUTOSAR since 2005, Green Hills provides both development tools and run-time environments for the safe and secure use of AUTOSAR Classic and AUTOSAR Adaptive.

Advanced AUTOSAR-aware multicore software development

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 AUTOSAR-based solutions. The advanced MULTI IDE offers:

  • ISO 26262 safety-certified development tools and C/C++ run-time libraries
  • advanced debugging of multiple software components running on multiple AUTOSAR Classic and/or Adaptive environments from various vendors, even across heterogenous cores on complex multicore SoCs
  • advanced time-synchronized system viewing that is OS and trace log agnostic with minimal intrusion
  • run forward and backward in time to find the most difficult bugs

Safe and secure execution

The INTEGRITY RTOS and its Multivisor secure virtualization provide the certified separation and guaranteed hardware resources to applications and their AUTOSAR components, including safety and security tasks, drivers, middleware, guest operating systems and AUTOSAR operating systems. The resulting freedom-from-interference is a vital feature to safely and securely run these complex mixed-ASIL software components with determinism, across multicore heterogenous SoCs.

For AUTOSAR Classic, the INTEGRITY RTOS executes one or more AUTOSAR Classic environments in virtual address spaces/containers across one or more cores on a high-performance multicore application processor. No virtualization is required. This means customers have 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 platform’s performance, safety architecture or security.

For AUTOSAR Adaptive, Green Hills again 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 hypervisor platform approach to AUTOSAR Adaptive in vehicle electronics designs.
