AvionicsPlatform: Zertifizierte Echtzeitbetriebssysteme & ARINC 653 Mikrokerne

AvionicsPlatform ARINC 653 Partitioned Real-Time Microkernel Architecture

Deterministic microkernel, hardware memory protection, and sampling/queuing channel bus

Central System: Certified RTOS Microkernel - DO-178C DAL A / ARINC 653 Core

Aviation Architecture Nodes

• Hardware Privilege Boundary
• Deterministic Microkernel Core
• Spatial Memory Protection Gate
• Cyclical Major Frame Scheduler
• Health Management (HM) System

Architectural Layers & Protocol Stacks

• Hardware Abstraction & Privilege Separation (ARM Cortex-R52 / PowerPC / RISC-V Safety Cores): Enforcing physical execution privilege rings: microkernel executes in supervisor mode while partitions execute in unprivileged user mode.
• Deterministic Microkernel Executive (Zero-Dynamic Allocation Microkernel / Formal C): Providing sub-microsecond context switches, deterministic priority ceiling mutexes, and zero unbounded loops.
• ARINC 653 Space/Time Partitioning Engine (Static MMU Translation Tables / Major-Minor Frames): Allocating dedicated physical memory and static execution windows for up to 32 concurrent mixed-criticality partitions.
• Certified Board Support Package (BSP) (Qualified Device Drivers / DMA Memory Ring Buffers): Interfacing with Ethernet, MIL-STD-1553, and serial controllers without kernel mode context switches.
