Realtime Schdeduling

                    RealTime Scheduling  (实时调度)

  • Correctnessof the system depends not only on the logical result of the computation butalso on the time at which the results are produced

  • Tasksor processes attempt to control or react to events that take place in theoutside world

  • Theseevents occur in “real time” and tasks must be able to keep up with them
