Abstract: An electronic device is provided. The electronic device includes a display, a display driver integrated circuit (DDI) including a clock generator and being operatively connected to the display, the DDI being configured to generate a hardware-based interrupt by using the clock generator, at least one processor operatively connected to the DDI, and a memory operatively connected to the at least one processor. The memory stores one or more instructions that, when executed, cause the at least one processor to receive a vertical synchronization (vsync) request associated with a frame displayed on the display, identify whether a software-based interrupt generated by an operation of the at least one processor is activated, and in response to determining that the software-based interrupt is not activated, prompt the DDI to activate the software-based interrupt without generating the hardware-based interrupt.

Abstract: According to various embodiments, an electronic device includes a housing configured to house a battery; a display configured to be disposed in the housing, to be exposed through a portion of the housing, and to be electrically connected to the battery; a motion detection sensor circuit configured to be disposed in the housing and to be electrically connected to the battery; a power management circuit configured to be disposed in the housing and to be electrically connected to the battery; and a processor configured to be functionally or electrically connected to the motion detection sensor circuit and the display and to be electrically connected to the power management circuit through a switch that is turned on when the processor is in a first mode and turned off when the processor is in a second mode, wherein, in the second mode, the motion detection sensor circuit detects a motion associated with the electronic device, and provides image data to the display in response to the detection of the motion. Other embodiments are also possible.
