Green Hills Software, the worldwide leader in high assurance operating systems, today announced the availability of its INTEGRITY Multivisor secure virtualization for the NXP Semiconductors i.MX 8 and 8X families of applications processors. For the first time, manufacturers of critical automotive and industrial systems can confidently run consumer operating systems in secure partitions alongside critical software applications on the same i.MX 8 processor, thanks to the certified separation architecture of the INTEGRITY real-time operating system and its Multivisor secure virtualization technology.
With the freedom to consolidate Linux, Android and AUTOSAR with critical software on the same i.MX 8-based platform, manufacturers can design a scalable mixed-criticality platform from which to build solutions targeting low, mid and high-end feature sets. In addition, the consolidated platform reduces hardware costs and simplifies software complexity.
Global automotive carmakers and their Tier 1 suppliers in North America, Europe and Asia have already chosen INTEGRITY Multivisor secure virtualization for tens of millions of vehicles requiring safe consolidation of Linux and Android environments with ASIL-certified applications such as digital instrument clusters, telematics and automated driving. The same secure virtualization capabilities enable safe consolidation in industrial systems for combining consumer operating systems and their human machine interfaces (HMI) with critical applications certified to the industrial standard IEC 61508.
INTEGRITY and INTEGRITY Multivisor are integrated with Green Hills Software’s advanced ASIL D/SIL 4 qualified development tools featuring the industry-leading C/C++ compilers, MULTI® integrated development environment, TimeMachine™ backward execution trace debugger, and MISRA C Adherence Checker. As a result, software developers utilize advanced tools to extract maximum performance from the i.MX 8 processors and reduce the time and cost to debug and test their software and meet project deadlines. For example, the MULTI debugger provides the programmer a time-synchronized and unified view and control of the many execution levels in a consolidated Linux system: Linux applications, Linux kernel and drivers, real-time applications, real-time operating system kernel and virtual machine monitor. In contrast, competing debuggers require a patchwork of different and disconnected debugging setups from several different vendors.
The INTEGRITY RTOS and Multivisor platform for NXP i.MX 8 and 8X families of applications processors includes support for:
- Secure virtualization and separation technology allowing ISO 26262 and IEC 61508-certified applications to coexist with general-purpose code or guest operating systems with freedom from interference. The platform can monitor the health of all applications and guest operating systems in real-time.
- Fully accelerated hardware virtualization leveraging the Arm architecture virtualization extension.
- Highly configurable virtualization platform allowing users to seamlessly configure peripheral routing and utilization between INTEGRITY RTOS and any guest operating system, including the ability to safely share peripherals between critical tasks and general-purpose tasks or guest operating systems.
- Fully accelerated 3D graphics utilizing i.MX 8 graphics processing unit (GPU), including the capability to fully share the GPU between the host RTOS and multiple guest operating systems, all while ensuring the RTOS graphics applications have guaranteed priority for meeting functional safety requirements.
- Complete AUTOSAR-compliant application framework, allowing existing AUTOSAR software components to be seamlessly and tightly integrated, providing for maximum software reuse without the need for virtualization.
- Advanced software development tools including the ISO 26262 ASIL D / IEC 61508 SIL 4 qualified MULTI IDE, optimizing C/C++ compilers, MISRA C Adherence Checker and other integrated tools to improve code quality and lower development costs.
INTEGRITY and its comprehensive set of integrated software and hardware tools for the NXP i.MX 8 and 8X families are used by customers today. INTEGRITY Multivisor for the i.MX 8 and 8X is available today to early access customers and demonstrated at the NXP Technology Days event in Detroit and Arm TechCon in San Jose.
