Abstract: There is provided an apparatus comprising scheduling circuitry, which selects a task as a selected task to be performed from a plurality of queued tasks, each having an associated priority, in dependence on the associated priority of each queued task. Escalating circuitry increases the associated priority of each of the plurality of queued tasks after a period of time. The plurality of queued tasks comprises a time-sensitive task having an associated deadline and in response to the associated deadline being reached, the scheduling circuitry selects the time-sensitive task as the selected task to be performed.
