COQOS Hypervisor SDK enables the convergence of several functionalities on a single hardware while providing freedom from interference between systems of different criticality. A typical use case is the safe cockpit controller that runs an instrument cluster and in-vehicle infotainment system simultaneously, on a single processor.
The core technology of COQOS Hypervisor SDK is the hypervisor. The hypervisor makes it possible to run several guest Operating Systems (including Linux, Android, AUTOSAR or other operating systems) in separated virtual machines. OpenSynergy’s hypervisor is a next generation hypervisor, taking full advantage of the newest hardware extensions and specially tailored to the needs of automotive applications. High efficiency and absolute functional reliability are achieved by a lean kernel and support for hardware virtualization. Guest operating systems such as Linux or Android do not need to be adapted to run in a VM. The applications on these guests achieve a performance approaching that of natively executed applications. The system is extraordinarily flexible, economical, and functionally reliable due to the minimal trusted code-base. OpenSynergy has applied its long-lasting experience and highly specialized automotive expertise to the development of this product.
On top of the hypervisor, the SDK provides modular features corresponding to the needs of the customer. The IXCF Communication Framework transfers data securely between the VMs: it provides virtual networking between the VMs and allows the efficient sharing of data and events. In addition, COQOS Hypervisor SDK contains the drivers required to share specific SoC resources, including sharing mass storage, graphics processing or displays.
For customers who need seamless integration of the ECU into the in-vehicle network, running multi-purpose software systems simultaneously on the same platform, COQOS Hypervisor SDK can provide a pre-integrated AUTOSAR environment in a dedicated VM. It offers the fastest option for installing standard AUTOSAR-compliant automotive services, such as diagnostics, and it makes possible to use AUTOSAR software components that implement real-time applications.
The COQOS hypervisor has been developed according to Automotive SPICE and ISO26262 ASIL-B practices.
