Speedify engineers discuss what separates a Real-Time Operating System (RTOS) like QNX from general-purpose operating systems like Linux, Windows, and macOS. QNX powers automotive dashboards, medical devices, and industrial control systems where microsecond timing failures aren’t an option.
Alex and Brian from Speedify break down:
- Microkernel vs monolithic kernel architecture: why QNX isolates failures that would crash Linux or Windows
- Determinism in RTOS: how QNX guarantees task completion within exact time windows, unlike general-purpose scheduling
- QNX safety certification: why automotive (ASIL) and medical device (IEC 62304) industries choose QNX over Linux
- Embedded systems architecture: how RTOS design decisions trace back to hard real-time requirements
