An application processor includes a memory controller, a display block and a power management unit. The memory controller controls an external memory that stores an image signal to be displayed on a display unit. The display block includes an internal frame buffer and a display controller and the display controller controls the image signal to be displayed on the display unit. The power management unit adaptively controls a power mode of the application processor based on a characteristic of the image signal to be displayed and a power control overhead index.
