Abstract
An application processor includes an application processor including a first processor configured to generate a control signal based on whether user data is changed, wherein the application processor is configured to implement a power manager which dynamically controls power provided to the first processor, in response to the control signal.
Claims20
An apparatus comprising:
- a check manager including a checker, a scheduler and a migrator;
- and
- a controller including a central processing unit (CPU) and a power management unit (PMU),
- wherein the CPU generates a control signal, and includes a first processor and a second processor,
- the PMU receives the control signal, and controls power supplied to the first processor and the second processor based on the control signal,
- the checker generates an indication signal indicating whether a user data is changed,
- the scheduler generates a reference value control signal based on the indication signal,
- the reference value control signal controls a reference value, and
- the migrator migrates a task between the first processor and the second processor in response to the reference value.

A system on chip (SoC) comprising:
- a central processing unit (CPU) configured to generates a control signal, the CPU including a first processor and a second processor;
- a power management unit (PMU) configured to receive the control signal, and to control power supplied to the first processor and the second processor based on the control signal;
- and
- a clock management unit (CMU) configured to dynamically control a clock signal applied to the CPU,
- wherein the first processor executes a first task, a workload of the first task being less than a reference value, and
- the second processor executes a second task, a workload of the second task being greater than the reference value.
