Patent number: 10496149Abstract: 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.Type: GrantFiled: August 30, 2016Date of Patent: December 3, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Gyeong Taek Lee, Ji Eun Park, Seung Kyu Kim

Patent number: 10474209Abstract: 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.Type: GrantFiled: November 2, 2016Date of Patent: November 12, 2019Assignee: Samsung Electronics Co., Ltd.Inventors: Jong Lae Park, Seung Kyu Kim

Patent number: 8797083Abstract: 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).Type: GrantFiled: March 3, 2010Date of Patent: August 5, 2014Assignee: Samsung Electronics Co., Ltd.Inventor: Seung Kyu Kim
