  • Power control method and apparatus for low power system of electronic device
    Patent number: 10809793
    Abstract: According to one embodiment of the present invention, a system on chip (SoC) including one or more intellectual properties (IPs) and a BUS, and a power control method using the same are provided, the SoC comprising: an IP-BUS activity monitor for measuring activity based on activity information of the respective IPs, for comparing with a pre-set activity threshold and for generating a first voltage control signal for the respective IPs based on the comparison result; and a voltage regulator for supplying voltage to the respective IPs based on the generated first voltage control signal.
    Type: Grant
    Filed: March 30, 2015
    Date of Patent: October 20, 2020
    Assignee: Samsung Electronics Co., Ltd.
    Inventors: Suhho Lee, Myungchul Cho
  • SYSTEM ON CHIP RECEIVING SUPPLY VOLTAGE(S) VIA MERGED POWER RAIL, AND MOBILE SYSTEM INCLUDING SAME
    Publication number: 20200089310
    Abstract: A mobile system includes a SOC and PMIC. The SOC includes a first signal processing circuit and a second signal processing circuit, and generates a dynamic voltage scaling (DVS) control signal based on operating states of the first signal processing circuit and the second signal processing circuit. The PMIC generates a supply voltage whose magnitude is controlled in response to the DVS control signal, and provides the supply voltage to the first signal processing circuit and the second signal processing circuit through a single power rail.
