An operating method of a system-on-chip (SoC) which includes a processor including a first core and a dynamic voltage and frequency scaling (DVFS) module and a clock management unit (CMU) for supplying an operating clock to the first core, the operating method including: obtaining a required performance of the first core; finding available frequencies meeting the required performance; obtaining information for calculating energy consumption for each of the available frequencies; calculating the energy consumption for each of the available frequencies, based on the information; determining a frequency, which causes minimum energy consumption, from among the available frequencies as an optimal frequency; and

System-on-chip and an operating method thereof

Disclosed is an apparatus for dynamic thermal management, which includes a thermal management unit that determines whether there is a need to perform thermal management on a processor based on temperatures measured from a plurality of temperature sensors included in the processor and generates an indication signal, and a controller that performs the thermal management on the processor in response to the indication signal, by using a first method of adjusting a state of each of a plurality of cores included in the processor, a second method of adjusting a level of an operating voltage and a frequency of a clock signal, which are provided to the processor, and/or a third method for adjusting only the frequency of the clock signal to be provided to the processor, and where each of the plurality of cores is in a wake-up state or an idle state.

Apparatus and method for dynamic thermal management using frequency clamping and idle injection

An electronic circuit includes a converter and a controller. The converter outputs a first voltage for a first cluster and a second voltage for a second cluster. When a first power to be provided to the first cluster based on the first voltage is lower than a first available power of the first cluster and a second power to be provided to the second cluster based on the second voltage is higher than a second available power of the second cluster, the controller outputs a first interrupt signal such that a level of the second voltage is adjusted based on a sum of the first power and the second power and a first threshold value determined based on the first available power and the second available power.

Electronic circuit for controlling power

Provided is a task scheduling method. The method may include: assigning a task to one of first processing units functionally connected to an electronic device; and migrating, at least partially on the basis of a performance control condition related to the task, the task to one of second processing units for processing.

Task scheduling based on performance control conditions for multiple processing units

A control method for a turbocharger system may include a first intake line supplying outdoor air to an intake manifold, a turbocharger, a second intake line supplying fresh air to the compressor; a third intake line connecting the compressor and the first intake line; a throttle valve controlling a flow of air supplied from the first intake line and the third intake line; an intake bypass valve controlling a flow of air that flows in the first intake line; a first exhaust line; a second exhaust line; an exhaust bypass valve controlling a flow of the exhaust gas discharged from the first exhaust line; and a controller controlling opening levels of the intake bypass valve, the exhaust bypass valve, and the throttle valve according to a driving condition of a vehicle.

Control method of turbocharger

An engine system may include an electric or mechanical supercharger and an LP-EGR, basically with a turbocharger, an EGR valve, a channel control valve, and a bypass valve, which control the flow rate of external air and exhaust gas, may be integrally operated, and a operation section may be divided into a turbo-lag and low torque section, a mid-load section, and mid/high-load section such that the open amount of EGR valve, channel control valve, and bypass valve may be optimally controlled, such that it may be possible to improve availability for a low-speed/high-load section with turbo-lag reduced, using supercharger and considerably increase the ratio of fuel efficiency improvement in the low-speed/high-load section, using LP-EGR operating with supercharger.

Engine system based on turbo charger and fuel ratio improving method thereof

A motorized vacuum pump apparatus, may include an electric motor operating in response to an electric signal, a pumping unit connected with a motor shaft of the electric motor, and a sound absorbing unit enclosing the pumping unit and having an inlet for sucking external air, a damping chamber and an outlet, wherein the sound absorbing unit is directly combined with the electric motor, and wherein the external air is compressed and supplied by the pumping unit to the damping chamber and discharged through the outlet such that noise is reduced by damping compressed air in the damping chamber.
