Abstract
A computer system having a process running unit which runs processes of a plurality of programs; a user input unit through which a command of a user to select one of a plurality of performance modes is inputted; and a controller which controls the process running unit to run a process of a program of the programs, which are currently being executed, according to a priority order corresponding to the performance mode selected by the command of the user if the command of the user is inputted.
Claims20
An apparatus comprising:
- a display;
- a processor to execute a plurality of computer programs;
- and
- a user input unit through which a user input is received to select one of a plurality of performance modes, each performance mode associated with a corresponding processor operating speed,
- wherein the user input unit for selecting the plurality of performance modes comprises a keyboard, wherein each of the plurality of performance modes is selectable based on keystroke inputs received via the keyboard, and the processor is operated at an operating speed corresponding to the processor operating speed associated with the selected performance mode,
- wherein the plurality of performance modes includes a first performance mode associated with a first processor operating speed and a second performance mode associated with a second processor operating speed different from the first processor operating speed,
- wherein a graphic image corresponding to the selected performance mode is displayed on the display in response to a predetermined keystroke input received via the keyboard.
4 more elements
An electronic apparatus comprising:
- a keyboard to receive a user input to switch from a normal performance mode to a high performance mode;
- a processor to reassign a higher priority to a program, which has been active with a priority in the normal performance mode, such that the program is executed with the higher priority in the high performance mode that otherwise would have been executed with the priority previously assigned;
- and
- a display screen to display a mode indication visibly indicating at least one of the normal performance mode or the high performance mode,
- wherein a user is able to select the normal performance mode or the high performance mode with one or more keystroke input through the keyboard without calling for a task manager dialog box, which is provided from an Operating System (OS) of the electronic apparatus, on the display screen, the task manager dialog box being used together with a selection window having one or more selectable options for the user to switch from the normal performance mode to the high performance mode, the selection window being provided from the OS of the electronic apparatus.
2 more elements
A method comprising:
- receiving user input through a user input unit to change from a normal performance mode to a high performance mode such that a currently active program among a plurality of programs is executed at a priority order higher than the normal mode, wherein the user input unit for selecting a plurality of performance modes comprises a keyboard;
- displaying a graphic image corresponding to the selected performance mode on a display in response to a determined keystroke input received via the keyboard;
- and
- executing a plurality of computer programs in the selected performance mode.
