AvionicsOS Kernel & Partitioning Architecture

Microkernel Separation, APEX ARINC 653 Interface & Static Time-Slice Table

Central System: DAL A Verified Microkernel - Space-Time Separation Engine

Aviation Architecture Nodes

  • APEX ARINC 653 Syscall Interface
  • Static Time-Slice Scheduler
  • POSIX PSE54 Thread Services
  • Hardware MMU Memory Barrier
  • Integrated Health Manager (HM)

Architectural Layers & Protocol Stacks

  • Formally Verified Microkernel Core (SPARK Ada / Formally Verified Microkernel Architecture): Minimal privileged codebase (under 10,000 lines of code) mathematically proven against deadlocks, null pointer dereferences, and memory leaks.
  • Time Partitioning & Deterministic Dispatcher (Static Cyclic Dispatcher / High-Resolution APIC Hardware Timers): Hard real-time cyclic scheduler executing partition windows with jitter bounded below 500 nanoseconds regardless of interrupt load.
  • ARINC 653 APEX & Inter-Partition Messaging (ARINC 653 Part 1 / Part 4 APEX Interface Specification): Certified sampling and queuing ports providing zero-copy memory transfers between isolated application partitions.
  • Health Management & Fault Containment (ARINC 653 Health Monitor (HM) / Partition Safe-State Fallback): Three-tier hierarchical fault isolation (Process, Partition, System) executing certified contingency responses upon anomalous hardware states.

Flight Telemetry Metrics: < 450 ns (Worst-Case Context Switch Latency) | 100% (DO-178C DAL A MC/DC Code Coverage) | < 10 KB (Privileged Kernel Footprint) | 0 leaks (Dynamic Memory Leak Failures)

실패가 선택지가 될 수 없는 운영체제

General-purpose operating systems are plagued by unbounded interrupt latencies, dynamic memory leaks, and unpredictable thread preemption. AvionicsOS is purpose-built from the ground up for zero-defect determinism, executing fly-by-wire flight control loops and integrated modular avionics with mathematical guarantees of safety.
