PORTABLE ELECTRONIC DEVICE AND CORE SWAPPING METHOD THEREOF

摘要

A portable electronic device is provided. A power management unit provides a first voltage and a second voltage. A multi-core cluster includes a first processing core configured to be powered by the first voltage and operate at a first operating frequency and a second processing core configured to be powered by the first voltage or the second voltage and operate at a second operating frequency. A third processing core is configured to be powered by the second voltage and operate at a third operating frequency. A first switch is configured to selectively provide the second voltage to the third processing core or stop providing the second voltage to the third processing core according to a first control signal. A second switch is configured to selectively provide the first voltage or the second voltage to the second processing core according to a second control signal.
