In this document, a case where the controller 180 is implemented using a quad core processor will be described as an example for convenience of description. That is, the case where it is implemented using a multi-core processor having four cores will be described as an example. However, it is clear that the present invention is not limited thereto. The technical idea of the present invention can be applied to all cases in which the controller 180 is implemented using a multi-core processor.

The controller 180 controls a clock or voltage input to each core 182, 183, 184, and 185 to control ON / OFF for each core 182, 183, 184, and 185. Alternatively, the cores 182, 183, 184, and 185 may be controlled to a sleep state or an active state.

In addition, the controller 180 may control performance by controlling an operating frequency for each core in an active state.

The performance of each core 182, 183, 184, 185 can be determined by the operating frequency of the core.

When the performance of each core is set through the menu screen 7, the controller 180 stores the set performance for each core in the memory 160 in response to the 3D image reproducing function.

Subsequently, when a 3D video playback is requested, the controller 180 controls an operation state of each core based on the performance of each core stored in the memory 160 in response to the 3D video playback function.

According to an embodiment of the present invention described above, the electronic device 100 provides a user interface through which the user can directly control the operating state or performance of each core, so that the user can operate the multi-core processor in a desired state. Can be controlled.

For example, a user who wants to maintain a lower power consumption than an operating speed can reduce power consumption by reducing the number of cores operating in an active state or lowering the performance of each core.

On the other hand, a user who wants to maintain a high operating speed even though the power consumption is high may increase the operating speed by increasing the number of cores operating in an active state or increasing the performance of each core.

In addition, according to an embodiment of the present disclosure, the electronic device 100 provides a user interface that allows a user to directly control the operation state or performance of each core for each application / function, thereby allowing the user to customize the application for each application / function. It supports the ability to set the behavior of multiprocessors to operate at the desired quality. Therefore, the user can control the operation of the multi-core processor at the time of executing each function / application according to the priority considered by the user.

The above-described method of controlling an electronic device according to the present invention can be provided by being recorded on a computer-readable recording medium as a program for execution on a computer.

The control method of the electronic device according to the present invention can be executed through software. When implemented in software, the constituent means of the present invention are code segments that perform the necessary work. The program or code segments may be stored in a processor readable medium or transmitted by a computer data signal coupled with a carrier in a transmission medium or communication network.

The computer-readable recording medium includes a mode type recording device in which data that can be read by a computer system is stored. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, DVD-ROM, DVD-RAM, magnetic tape, floppy disk, hard disk, optical data storage device, and the like. The computer readable recording medium can also be distributed over network coupled computer devices so that the computer readable code is stored and executed in a distributed fashion.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. The present invention is not limited to the drawings, and all or some of the embodiments may be selectively combined so that various modifications may be made.
