Abstract: A method of operating a CPU including a memory for storing a load tracker and a booster and a core for executing the load tracker and the booster includes determining, by the load tracker, whether an idle task is executed in the core, generating, by the load tracker, an event corresponding to a result of the determination, broadcasting, by the load tracker, a generated event to the booster, and setting, by the booster, a QoS minimum value of the core based on the event. The method of operating a CPU may further include registering, by the load tracker, an idle start worker callback and an idle end worker callback in an idle module when the CPU is initialized, and generating, by the load tracker, an idle start worker and an idle end worker when the CPU is initialized.

Abstract: In one example embodiment, an integrated circuit includes a memory configured to store a first table listing a plurality of clip frequencies respectively corresponding to a plurality of reference temperatures, and a second table listing one or more of the plurality of clip frequencies and a plurality of timestamps each respectively corresponding to the one or more of the plurality of clip frequencies. The integrated circuit further includes a cooling frequency adjustor configured to select one of the plurality of clip frequencies stored in the first table as a first clip frequency, and store a current timestamp of the first clip frequency in the second table. The integrated circuit further includes a central processing unit (CPU) configured to control an operation of the cooling frequency adjustor.

Abstract: An application processor includes a first core and a second core. The first core is configured to implement a scheduler which monitors a workload of a task of the first core, and the first core is further configured to implement an idle checker which determines whether the second core is idle.

Abstract: An organic electroluminescent display device, includes: a gray level extractor that extracts gray levels of frame data signals for a frame image; an image type determiner that determines a type of the frame image using a distribution of the gray levels of the frame data signals, the type of the frame image being one of a low-gray-level type, a medium-gray-level type and a high-gray-level type; a gamma reference voltage generator that selects a set of gamma reference voltages based upon the image type; a data driver converting the frame data signals into frame data voltages using the selected set of gamma reference voltages; a timing controller that supplies the frame data signals to the data driver; and a display area including pixels having an organic light emitting diode that display the frame image.

Abstract: The present invention provides a lead-free solder composition for glass. The lead-free solder composition for glass includes indium, zinc, and tin. The indium (In) ranges from about 30.0 wt % to about 60 wt %. The zinc (Zn) ranges from about 0.01 wt % to about 11.0 wt %. The tin (Sn) is included as a remaining component.

Abstract: Methods of operating timers include generating a periodic timing signal having a first frequency that differs from a desired timer frequency (1 KHz) by a first amount. This periodic timing signal having the first frequency can be generated by dividing a frequency of an input clock signal (e.g., 32.768 KHz) by N, where N is a positive integer greater than one. A typical value of N may be 32. The methods also include techniques to inhibit timing error accumulation by switching a frequency of the periodic timing signal from the first frequency to a second frequency that differs from the desired timer frequency by a second amount. This periodic timing signal having the second frequency can be generated by dividing the frequency of the input clock signal by M, where M is a positive integer unequal to N (e.g., M?N equals ±1).
