Real-Time Operating Systems

• Interrupts signal the need for follow-up tasks.

  • But, unlike Function-Queue Scheduling, this is handled by the Real-Time Operating System and not by the interrupt routines manipulating flags or a queue.

• Instead of a loop deciding what to do next the RTOS decides.

• One follow-up task can be suspended by the RTOS in favoring of performing a higher priority task.

  • Biggest difference compares to Function-Queue Sched.
