Ever wondered how your smartwatch responds instantly, or how medical devices precisely administer medication? The silent powerhouse behind these critical applications is the Real-Time Operating System (RTOS).
Unlike general-purpose operating systems (GPOS) like Windows, an RTOS is purpose-built for deterministic and time-constrained environments. This guarantees critical tasks execute within predictable timeframes, making it essential for embedded systems, IoT devices, industrial control, and automotive electronics where reliability and precise timing are crucial.
This curated list of resources will help you understand, learn, and master Real-Time Operating Systems, whether you're a beginner or seeking to deepen your expertise.
