In collaboration with Vector, Green Hills Software is to make the INTEGRITY Real-Time Operating System (RTOS) capable of native execution of MICROSAR, the AUTOSAR basic software from Vector. This development makes it possible to run MICROSAR on INTEGRITY-based ECUs.
In addition, one can consolidate a range of vehicle services on one microcontroller in order to simplify and cost-reduce the implementation of OEM-specific services.
Developers of high-performance INTEGRITY or INTEGRITY Multivisor-based ECUs for domain controllers, Advanced Driver Assistance Systems (ADAS), next-gen digital clusters and modern infotainment systems will now be able to benefit from enabling MICROSAR features for a full range of automotive requirements, including the ability to realise OEM-specific diagnostic services, time-sensitive applications for streaming media data – such as Audio Video Bridging (AVB) – and applications using specific automotive protocols including SOME/IP.
The latest generation of Electronic Control Units (ECUs) have increasing demands for computing power and memory. Dynamic memory management is often a requirement for new application areas. To consider the needs of modern automotive architectures, established ECU designs with proven AUTOSAR operating systems often supplement sophisticated systems that utilise increasingly powerful microprocessors. To address this need, many systems make use of two separate microcontrollers to run MICROSAR and INTEGRITY in parallel. With this latest support from Green Hills Software, the ISO 26262 and IEC 61508-certified INTEGRITY RTOS and MICROSAR can be integrated seamlessly and are able to deliver reduced system costs by sharing a single controller.
Vector’s support for new automotive-specific communication mechanisms, such as SOME/IP and Service Discovery, means that INTEGRITY-based ECUs can immediately interact with these new, service-oriented AUTOSAR clients.
Streaming video or audio data in a car network is becoming a standard requirement for instrument clusters and infotainment systems. Audio/video broadcasting systems have strict requirements for timing, shaping and Quality of Service (QoS) of IP streams. With the MICROSAR basic software for Ethernet, INTEGRITY-based ECUs are now able to fully support AVB (Audio Video Bridging) functionality.
