Abstract
A method and apparatus for controlling power in a low-power multi-core system, including receiving task information from an Operation System (OS) kernel upon start and end of a task, estimating a future CPU usage using a current CPU usage in the task information, monitoring memory-related information in the task information, comparing a change in the current CPU usage with the monitored memory-related information, establishing a policy for power control based on the estimated CPU usage and the monitored memory-related information, and controlling on/off of multiple cores according to the established policy. By doing so, it is possible to solve the problems caused by performing DPM using only the CPU usage.
