For the first time, manufacturers of critical automotive and industrial systems will now be able to confidently run consumer operating systems in secure partitions alongside critical software applications on the same i.MX 8 processor, due to the certified separation architecture of the INTEGRITY real-time operating system and its Multivisor secure virtualization technology.
Being able to consolidate Linux, Android and AUTOSAR with critical software on the same i.MX 8-based platform, manufacturers will be able to 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.
“Built with advanced media processing, secure domain partitioning and innovative vision processing, the i.MX 8 and 8X families of applications processors revolutionise multiple display automotive applications and graphics-rich industrial systems,” said Ron Martino, vice president, i.MX applications processors product line at NXP. “Green Hills Software’s secure virtualization services enable global carmakers and their suppliers to confidently partition Android and Linux environments from critical automotive tasks to help them realise quantitative competitive advantages on their production programs.”
INTEGRITY and INTEGRITY Multivisor are integrated with Green Hills Software's advanced ASIL D/SIL 4 qualified development tools featuring C/C++ compilers, MULTI integrated development environment, TimeMachine backward execution trace debugger, and MISRA C Adherence Checker. As a result, software developers utilise 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.
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, optimising C/C++ compilers, MISRA C Adherence Checker and other integrated tools to improve code quality and lower development costs.
