ABSTRACT:
The subject matter provides dynamically variable idle time thread scheduling in a device with a high system tick rate. A device based on the subject matter includes an operating system, a set of application program modules, and one or more hardware elements. A thread scheduling mechanism in the operating system schedules threads at a periodic rate. Upon determining that there are no threads to execute, at least a subset of components are deactivated for a dynamic variable amount of time before they are is re-activated. The at least one subset of components are selected from the hardware elements, one or more program modules comprising the operating system, and the like. The dynamic variable amount of time is independent of the periodic rate and based on a sleep state of a set of threads in a sleep queue.
