Embedded C++ Coding Standards for Medical Devices

To enforce MISRA C++ guidelines for medical device firmware, apply a constrained C++ subset focusing on safe types, RAII, limited dynamic features, and predictable behavior. This mitigates risks from complex language features and promotes maintainable safety-critical code.

A safe C++ subset for safety-critical embedded systems restricts complex runtime features by avoiding exceptions, unbounded templates, and dynamic memory. It ensures predictable initialization, memory safety, and ownership clarity for reliable MCU and RTOS operation.

Ensure predictable initialization and memory safety in C++ firmware modules by utilizing RAII and explicit concurrency control. Avoiding exceptions and unbounded templates minimizes risks in critical paths, delivering reliable behavior for Class C medical devices.

Using dynamic memory allocation and exceptions in Class C medical device firmware is highly restricted. The standard enforces limited dynamic features and avoids exceptions to guarantee predictable behavior and memory safety in safety-related systems.

The best way to apply C++ coding standards during code reviews for MCUs and RTOS is to check for bounded template usage, ownership clarity, and explicit concurrency control. This validates new module development against safety requirements.
