For example, the governor of the central processing module may include'ondemand','hotplug','conservative','performance','smartass', and the like. Each governor has a different method of setting the clock, and the operation speed of each sub-module can be adjusted according to the set clock.

Specifically, the control unit may determine a specific sub-module that requires a maximum operation speed according to an operation mode of the system, and determine a governor of a specific sub-module so that the specific sub-module is driven at the maximum operation speed. Assuming that the operation speed decreases in the order of A governor, B governor, C governor, etc., the control unit displays the specific sub-module requiring the maximum operation speed in'Game mode' as a graphic module, sound output module, memory management module, communication You can decide by module. The sub-modules requiring the maximum operating speed are controlled to select the A governor, and the governor of the other sub-modules, the central processing module and the display module, can be set as the B governor or C governor.

As described above, the controller may determine the operation speed of each sub-module according to the set system operation mode, and drive each sub-module at the determined operation speed. The controller may control to decrease the performance of other sub-modules relatively, instead of increasing the performance of a specific sub-module requiring the maximum operating speed.

The controller may divide the system operation mode of the terminal into two or more, and determine the operation speed of each sub-module in each system operation mode in advance and store it in a memory. For example, the controller may divide the system operation mode of the terminal into'Hight user mode','Game mode','Audio mode','Light user mode','Normal mode', and'Battery save mode'. Specifically, the'High performance mode' is a mode in which the operation speed of the central processing module is set to maximum in order to perform high-speed calculation. 'Game mode' is a mode that sets the maximum operating speed of the graphics module to maximize the performance of the game application. 'Audio mode' is a mode in which the operating speed of the sound output module is set to maximum in order to maximize a music or video playback function. 'Light user mode' is a mode that can improve the operation speed of other sub-modules when an application with a small amount of computation is mainly used. 'Normal mode' is a mode set when manufacturing the terminal. 'Battery save mode' is a mode that sets the operation speed of all sub-modules to a minimum. In addition, when the system operation mode of the terminal is'Audio mode', the control unit may set the operation speed of the sound output module to the maximum, and set the operation speeds of other sub-modules to be relatively lower than in the normal operation mode.

The controller of the mobile terminal (180 in FIG. 1A) may display a list of at least one system operation mode stored in the user interface (S220).

Specifically, when the system operation mode of the terminal is previously classified and set, the controller may display at least one system operation mode as a list.

When receiving an input for a specific system operation mode among at least one of the displayed system operation modes (S230), the control unit of the mobile terminal (180 in FIG. 1A) may select a specific system operation mode and set the system operation mode of the terminal. (S240).

The control unit may select a specific system operation mode when receiving a touch input for a specific system operation mode from the list. If the selected specific system operation mode is the same as the previous system operation mode, the controller may maintain the previous system operation mode. In addition, when the selected specific system operation mode is different from the previous system operation mode, the controller may change the previous system operation mode to the selected specific system operation mode. When the system operation mode is changed, the control unit may display the setting or change contents through a pop-up window or an indicator.

The control unit of the mobile terminal (180 in FIG. 1A) may adjust the operation speed of at least one sub-module according to the set system operation mode (S250). This step has been described in detail in the first embodiment, so the description will be omitted.

Specifically, the control unit displays the names of six system operation modes'High performance mode','Game mode','Audio mode','Light user mode','Normal mode', and'Battery save mode' on the execution screen. Can be displayed.

When receiving a user input for'Audio mode', the controller may manually set'Audio mode' as an operation mode of the system. In this case, the control unit may display the manually set system operation mode in the pop-up window (W). The controller may manually change the system operation mode according to the user's selection.

Even if the system operation mode of the terminal is set by the user manual setting, the controller may automatically change to another system operation mode when it is determined that driving is not possible with the system operation mode set in consideration of the state information of the terminal.

Therefore, according to the second embodiment, the user can autonomously determine the system operation mode, and in a specific situation, the system operation mode is automatically changed automatically to keep the terminal running smoothly.
