Advantages

• Latency for high priority devices can be reduced compared to Round-Robin with Interrupts

  • (C,C,C,C,A,C,C,B) is simply a matter of the queuing algorithm.

• In Round-Robin with Interrupts every loop may end up executing every follow-up task.

  • Function-Queue Scheduling guarantees that at most a single follow-up task is executed per loop iteration.
