New 64-bit Support for ARM®v8-A and Intel Architecture Builds on a Decade-Plus of Deploying Cross-Industry Safe and Secure Real-Time Virtualization

Green Hills Software, the worldwide leader in high assurance operating systems, has announced the availability of its safe and secure INTEGRITY® Multivisor™ virtualization solution for 64-bit ARM® and 64-bit Intel Architectures. Based on the INTEGRITY real-time operating system, INTEGRITY Multivisor delivers a real-time, fast-boot platform for safely and securely combining consumer operating systems such as Linux, QNX, Android or Windows with safety- and security-critical software on next-generation 64-bit multicore processors. As a result, device manufacturers can combine separate system components into a single cost- and size-reduced platform while still being able to satisfy rigorous market-specific requirements for safety, security and real-time performance.

Why Virtualization for Embedded Devices?

Green Hills Software’s secure, deterministic high-performance virtualization solution brings powerful new capabilities to designers of embedded devices – whether for automotive cockpits, medical devices, industrial electronics, aircraft mission computers or government-sensitive dual-persona mobile devices. For more than 10 years, device manufacturers have successfully leveraged INTEGRITY Multivisor virtualization on 32-bit processors. Now they can do the same for the latest 64-bit processor architectures:

  • Consumer OS Ecosystems – Concurrently run one or more 32-bit or 64-bit guest operating systems such as Linux, QNX, Android or Windows with guaranteed freedom-from-interference, shared peripherals and near-native performance.

  • Smaller footprint – Decrease the size, weight, complexity and cost of the hardware platform by consolidating several multi-function processors, their wiring and peripherals into a single processor platform while maintaining safe separation and defined processor resource allocation for essential software tasks.

  • Safely mix critical and general purpose functions – Some systems, such as aircraft mission computers or automotive cockpits, greatly benefit from a software architecture that enables the consolidation of functions at different levels of criticality, a benefit only realized through the trusted execution of multiple functions running concurrently.

  • Configurable product family – By drawing from a proven and scalable software platform, like INTEGRITY, device manufacturers gain the flexibility to easily configure product capabilities, enabling agile response to market needs, while realizing greater return on software investment.

“ARM and Intel 64-bit architectures provide a compelling compute platform for next-generation software-defined devices over a variety of embedded markets,” said Dan Mender, vice president of business development, Green Hills Software. “INTEGRITY Multivisor delivers a proven, field-tested solution with a configurable mix of consumer ecosystems safely combined with safety- and security-critical real-time system services – providing significant cost and time-to-market savings to our customers.”

INTEGRITY Multivisor is the only hypervisor based on software technology independently certified to the highest levels of safety and security. A summary of its comprehensive development and support offering is as follows:

  • INTEGRITY Multivisor combines a trusted 64-bit INTEGRITY microkernel with multicore system virtualization for configurable software partitions, real-time and safety-critical processing and hosting of one or more guest operating systems.
  • Maximum virtualization performance through hardware acceleration built in to the ARM®v8-A architecture and Intel Virtualization Technologies (Intel VT-x and VT-d), for both 32- and 64-bit processors.
  • Safely share peripherals between critical tasks and guest operating systems.
  • Green Hills Software’s MULTI® integrated software development environment featuring multicore debugger, TimeMachine™ suite, 64-bit optimized C/C++ compilers, MISRA C support, profiler and many other integrated time-saving tools.
  • Green Hills Software’s family of hardware probes for hardware bring-up, low-level debugging and trace-powered visibility.
  • Green Hills Software’s embedded experts collaborate with system designers and architects to tackle the difficult challenges of legacy code porting, reuse, virtualization, device driver configuration and optimization, along with consulting services for general system performance optimization.
