    摘要: 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.

    摘要: 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.
