Universalisos - Type-1 Hypervisor Foundation
Universalisos is our safety-critical type-1 hypervisor foundation for cyber-physical systems, created from zero based on PikeOS architecture. This project imports the complete PikeOS ecosystem to serve as the reference architecture and codebase for Aurelio cyber-physical brain development.
Strategic Objectives
- Type-1 Hypervisor: Safety-critical embedded systems foundation
- AUTOSAR C++ Compliance: MISRA C++, MISRA C, DAL-B, DAL-A (avionics), ISO26262
- Aurelio Integration: PikeOS codegen workflow → Aurelio implementation patterns
- IP-XACT Architecture: Agent components as IP Cores with standard interfaces
- Airship Control Foundation: Type-1 hypervisor for cyber-physical simulation control
