Abstract
The present disclosure relates to an apparatus and a method for controlling a central processing unit in a portable terminal The method includes: operating a first core among multiple cores included in the central processing unit within a range of pre-designated limited clock frequencies; identifying the number of work queues corresponding to the number of processings being delayed by the central processing unit; comparing the identified number of work queues with a pre-designated reference value; and operating the first core and a second core among the multiple cores at a maximum clock frequency when a result of the comparison shows that the identified number of work queues exceeds the reference value.

An apparatus for controlling a central processing unit (CPU) in a portable terminal, comprising:
- a controller for operating a first core among multiple cores included in the central processing unit within a range of pre-designated limited clock frequencies, identifying a number of work queues corresponding to a number of processings being delayed by the CPU, comparing the identified number of work queues with a pre-designated reference value, and operating the first core and a second core among the multiple cores at a maximum clock frequency when a result of the comparison shows that the identified number of work queues exceeds the pre-designated reference value.
An apparatus for controlling a central processing unit (CPU) in a portable terminal, comprising:
- a plurality of cores;
- a load detector for identifying a number of work queues that the CPU must process;
- and
- a core determiner for comparing the identified number of work queues with a pre-designated reference value,
- wherein a first core and a second core operate at a maximum clock frequency when the identified number of work queues exceeds the pre-designated reference value.
A method for controlling a central processing unit (CPU) in a portable terminal, the method comprising:
- operating at least one core among multiple cores included in the CPU within a range of pre-designated limited clock frequencies;
- identifying a number of work queues corresponding to a number of processings being delayed by the CPU;
- comparing the identified number of work queues with a pre-designated reference value;
- and
- operating at least a first core and a second core among the multiple cores at a maximum clock frequency when a result of the comparison shows that the identified number of work queues exceeds the pre-designated reference value.
