Dynamic memory allocation ( malloc/free ) is generally discouraged in hard real-time systems because it is non-deterministic and can lead to memory fragmentation. Instead, engineers use or Memory Pools of fixed-size blocks. The Watchdog Timer (WDT)

Code that talks to the silicon. Middleware/RTOS: Managing concurrency and memory. Application Layer: The specific business logic. Memory Management Dynamic memory allocation ( malloc/free ) is generally
The defining characteristic of a real-time system is that its Determinism vs. Throughput Dynamic memory allocation ( malloc/free ) is generally
Real-Time Embedded Systems: Design Principles and Engineering Practices
For those looking for a deep dive into specific implementation details, many professional organizations provide comprehensive on RTOS standards (like MISRA C or POSIX) which serve as the gold standard for engineering practices in the field.
