Abstract: A display driving circuit for receiving image data from a host and driving a display panel, the display driving circuit including: an interface configured to receive the image data from the host; and a timing controller configured to control a first interrupt signal for waking up the host in a low-power mode and to control a second interrupt signal based on a light emission control signal, wherein the light emission control signal is for controlling a light emission time of a pixel included in the display panel, and wherein the timing controller is further configured to control a level of the second interrupt signal based on whether the image data has started to be received from the host in response to the first interrupt signal and the second interrupt signal.

Abstract: An apparatus and a method for controlling a home device using biometric information are provided. The method includes determining a reference sleep pattern among a plurality of sleep patterns based on sleep time information of a user or basic information of the user, analyzing a sleep state of the user based on biometric information of the user, comparing the reference sleep pattern with the sleep state, determining a sleep environmental condition when the reference sleep pattern is different from the sleep state, and controlling the home device based on the determined sleep environmental condition.

Abstract: A Dynamic Voltage and Frequency Scaling (DVFS) controller, an integrated circuit including DVFS, and a method of operating the DVFS controller are provided. The integrated circuit includes at least one subblock circuit configured to process an instruction, and a DVFS controller configured to control a power management unit (PMU) and a clock management unit (CMU) to control an operating voltage and an operating frequency, respectively, based on a resonance frequency calculated from a frequency response resulting from dynamic characteristics of an entire power system including the PMU, a power delivery network (PDN), and the subblock circuit.
