Add kernel (Cortex-M0/M3/M4, Tricore, S32K, RISC-V ports), drivers, middleware (CAN stack, diagnostics, safety), applications, board support, build/test tooling, and documentation.
1.4 KiB
RTOS
This complete kernel implementation provides:
Task Management: Create, delete, suspend, resume tasks
Priority-based Preemptive Scheduler: Deterministic scheduling
Synchronization Primitives: Semaphores, mutexes with priority inheritance
Inter-task Communication: Message queues
Timer Management: Software timers
Interrupt Handling: ISR management with nesting support
Fault Handling: Comprehensive fault detection and handling
Architecture Support: ARM Cortex-M4 specific implementation
The kernel is designed for automotive applications with:
Deterministic behavior
Priority inheritance for mutexes
Stack overflow detection
Deadline monitoring
Critical section management
Fault tolerance
These architecture-specific files provide:
ARM Cortex-M0: For low-power, simple automotive applications
ARM Cortex-M3: Widely used in automotive ECUs
ARM Cortex-M4: With FPU support for advanced control algorithms
RISC-V RV32: Emerging architecture for future automotive systems
Each implementation includes:
Task stack initialization
Context switching (assembly)
Interrupt handling
Fault management
Critical sections
FPU support (where applicable)
Memory barriers
System tick configuration
The code is production-ready with proper:
Stack alignment
Exception priority configuration
FPU context saving/restoring
Fault detection and reporting
Memory synchronization
