Interrupt Handling in Medical Devices

Safe interrupt handling in medical device firmware requires minimal, non-blocking ISRs that defer processing to tasks. This approach ensures predictability, latency control, and data consistency across safety-relevant timing paths.

Assigning interrupt priorities in real-time embedded systems requires aligning priority levels with safety and timing requirements. Proper priority management ensures critical sensor interrupts are handled efficiently without compromising system stability.

Protecting shared data between ISRs and tasks in embedded C requires strict critical section management. This strategy prevents data corruption and ensures data accuracy when handling concurrent interrupt-driven features.

Data consistency loss during sensor interrupts often occurs when ISRs perform blocking work instead of minimal operations. Deferring processing to tasks and enforcing critical section management restores data integrity and predictability.

Interrupt handling in medical devices requires verification through testing and fault injection. This testing satisfies safety requirements for predictability and latency control in safety-relevant timing paths.
