Many non-real-time operating systems also provide similar kernel services. The key difference between general-computing operating systems and real-time operating systems is the need for ” deterministic ” timing behavior in the real-time operating systems. Formally, “deterministic” timing means that operating system services consume only known and expected amounts of time. In …

Thread executes for duration of time slice, unless it voluntarily stops (via a system delay or yield function) RTX changes to next READY thread with same priority

The most important factors of real time systems are the worst case response time of a task and worst case response time of an interrupt [Sohal 2001]. However, it makes no sense to analyze real time operating systems metrics such as interrupt latencies and task switching time without considering different CPU usage scenarios [Timmerman et al. 1998], as it is easier for a system to be more

The scheduler in a Real Time Operating System (RTOS) is designed to provide a predictable (normally described as deterministic) execution pattern. This is particularly interesting for embedded systems, like the Arduino devices, as embedded systems often have real time requirements.
26/11/2006 · A real-time operating system (RTOS) is a class of operating system intended for real-time applications, including embedded systems (programmable thermostats, household appliance controllers, mobile telephones), industrial robots, spacecraft, industrial control (see SCADA), and scientific research equipment . It is an advance topic in Microcontroller and Embedded Systems.
