Opensynergy Improves Virtual Platform to Support Android Automotive OS Fully
OpenSynergy has announced today the release of an enhanced version of their automotive reference platform for virtual Android™ (based on Trout) with Android 12 MVP 1.0 ready for series production.

OpenSynergy has announced today the release of an enhanced version of their automotive reference platform for virtual Android™ (based on Trout) with Android 12 MVP 1.0 ready for series production. Containing technology from Google, the reference platform highlights the integration of the Virtual I/O (VIRTIO) framework into Android Automotive OS (AAOS). More importantly, the reference platform now offers a complete vehicle-ready solution due to the fact that OpenSynergy has specified and implemented devices necessary for automotive use cases. This allows Android to run fully virtualized on any solution containing the newest VIRTIO device implementation. Additionally, VIRTIO  enables support for multiple System on Chip(SoC)s, and provides higher flexibility to change hardware.

VIRTIO is an established virtualization standard maintained by the OASIS Open consortium. It provides a device-sharing framework for devices such as blocks, networks, consoles, graphics processing units (GPUs), input, etc. OpenSynergy assumes the role of an automotive expert in the consortium specifying missing automotive-specific VIRTIO devices to expand the scope of the open standard in the automotive domain such as sound, video, Bluetooth®, camera, GNSS, and more. Thanks to the OASIS consortium’s active membership and expertise gathered in the open-source domain, OpenSynergy always provides a mature virtual platform equipped with the very latest VIRTIO devices already shipping in a large number of cars.

OpenSynergy’s latest COQOS Hypervisor SDK supports VIRTIO devices required for automotive use cases, allowing customers to fully leverage the virtualized AAOS reference platform. The cooperation between OpenSynergy and Google ensures that Android™ Automotive OS is fully compatible with the COQOS Hypervisor SDK. As Android Automotive OS can be deployed fully virtualized, customers enjoy the quick integration of Android onto their hardware, easy upgrade of Android versions, as well as easier CTS certification by using a pre-CTS tested Android (AOSP).

Operating systems fully compliant with this open VIRTIO standard can be flexibly deployed and reused across any hardware and hypervisors adhering to the standard. As an example, OpenSynergy has successfully collaborated with several Tier1s to transition and upgrade their infotainment systems already in series production to newer hardware and the latest Android version in the span of only a few months. This maximum flexibility gives OEMs and Tier1s the freedom to choose any chipset vendor for their series projects, which is especially useful to accelerate the move to more powerful hardware, supporting the rapid introduction of additional features. At the same time, this flexibility is crucial in times of silicon shortage.

OpenSynergy’s reference platform showcases an Android Automotive OS-based Cockpit Domain  Controller (CDC) architecture. Similar to other CDCs, the underlying hypervisor guarantees the secure coexistence of Android (typically a QM system) with systems of higher criticality, such as the real-time OS displaying the telltales on an Instrument Cluster (typically ASIL B).

The reference platform software is available from OpenSynergy. It contains the VIRTIO-based  COQOS Hypervisor SDK as well as links and tools to download and build AAOS.
