V2XHypervisor: Mixed-Criticality Virtualization for Connected ECUs

V2XHypervisor establishes strict spatial and temporal isolation between safety-critical V2X communication stacks and non-critical cloud telematics running on consolidated automotive processors.

Consolidating Safety-Critical Sidelink and Infotainment onto One Silicon Die

Modern software-defined vehicles run Linux telematics, Android infotainment, and ASIL-D brake control on a unified cockpit/gateway SoC. V2XHypervisor guarantees safety-critical V2X packets never experience starvation or memory corruption from adjacent VMs.

Core Engineering Areas

• Type-1 Microkernel Architecture — Eliminating dynamic memory allocation and unbounded loops inside the virtualization hypervisor layer.
• I/O Virtualization & SR-IOV — Direct DMA access for safety-critical VMs while preventing memory snooping across virtual boundaries.
• Safe Inter-VM Communication — Streaming telemetry from untrusted Linux containers to ASIL safety monitors without kernel traps.
