Abstract: 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.

Abstract: A gas mixing device may include a main conduit and a gas transferring device connected to the main conduit. The gas transferring device may include a distribution device surrounding the main conduit, a supplying conduit connected to the distribution device and defining a supplying path, and a plurality of connection conduits connecting the first distribution device to the main conduit. The distribution device may include inner and outer cylinders, which are sequentially provided to surround the main conduit and are sequentially spaced apart from the main conduit in a radial direction. A distribution space may be defined between the inner and outer cylinders, and the supplying conduit may be coupled to the outer cylinder, such that the supplying path is connected to the distribution space. The connection conduits may be spaced apart from each other in a circumferential direction.

Abstract: 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



adjusting an operating frequency to be supplied to the first core to the optimal frequency.

Abstract: 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.
