Interrupt handlers are included in a fixed priority analysis by treating them as

  • A.tasks of higher priority than every application task
  • B.part of the kernel's overhead, spread evenly over the tasks
  • C.tasks of the lowest priority in the system
  • D.blocking terms added to the task they interrupt

Answer: A

Hardware priority puts every handler above every task whatever the kernel's own priorities say, so they enter the recurrence as the topmost interference. Their periods are the minimum interarrival times of the events that trigger them.
