OpenSynergy Enhances Virtual Platform to Fully Support Android Automotive OS

Automakers can now deploy the latest Android Automotive operating system with significantly reduced integration effort

BERLIN, September 22, 2022 /PRNewswire/ — OpenSynergy today announced the release of an enhanced version of its automotive benchmark platform for Virtual Android™ (based on Trout) with Android 12 MVP 1.0 ready for mass production. Containing Google’s technology, 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, as OpenSynergy has specified and implemented the devices needed for automotive use cases. This allows Android to run fully virtualized on any solution containing the latest VIRTIO device implementation. Additionally, VIRTIO enables support for multiple system-on-chips (SoCs), and provides greater 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 block, network, console, graphics processing unit (GPU), input, etc. OpenSynergy assumes the role of an automotive expert in the consortium by specifying missing automotive-specific VIRTIO devices to extend the scope of the open standard in the automotive field such as audio, video, Bluetooth®, camera, GNSS, etc Thanks to the active membership of the OASIS consortium and the acquired expertise in the open-source field, OpenSynergy always provides a mature virtual platform equipped with the latest VIRTIO devices already delivered in a large number of cars.

OpenSynergy’s latest COQOS hypervisor SDK supports the VIRTIO devices required for automotive use cases, allowing customers to take full advantage of 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 benefit from rapid integration of Android on their hardware, easy upgrade of Android versions, as well as easier CTS certification using a Android pre-tested by CTS (AOSP).

Operating systems fully compliant with this open VIRTIO standard can be deployed and reused flexibly on all hardware and hypervisors adhering to the standard. For example, OpenSynergy has successfully worked with several Tier1s to transition and upgrade their already-in-production infotainment systems to newer hardware and the latest version of Android in just a few months. This maximum flexibility gives OEMs and Tier1s the freedom to choose any chipset vendor for their production projects, which is particularly useful for accelerating 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 presents a Cockpit Domain Controller (CDC) architecture based on Android Automotive OS. Similar to other CDCs, the underlying hypervisor ensures the secure coexistence of Android (usually a QM system) with higher criticality systems, such as the real-time operating system displaying cookies on a group instruments (usually ASIL B).

Reference platform software is available from OpenSynergy. It contains the VIRTIO-based COQOS hypervisor SDK as well as links and tools to download and create AAOS.
