Abstract
A power control method of a Central Processing Unit (CPU) in a multi-core system. The power control method includes acquiring current usage information of the CPU and system information, estimating a CPU usage of a next time interval based on the acquired current usage information, calibrating the estimated CPU usage of the next time interval based on the acquired system information, and determining a power control mode based on at least one of the acquired system information and the calibrated CPU usage of the next time interval.
