  • Method for managing power supply of multi-core processor system involves powering off main and slave cores when master bus is in idle state
    Patent number: 8977880
    Abstract: A multi-core processor system, a dynamic power management method thereof and a control apparatus thereof are provided. In the method, a workload of a multi-core processor during a runtime stage is obtained. Next, a hot-plug operation is respectively performed on a plurality of slave cores according to the workload and a working state of each slave core. Then, a bus master status and the working state of a boot core are monitored to determine whether to power off the boot core, in which the bus master status is generated by combining a plurality of device statuses reflected by a plurality of peripheral devices. Finally, when the bus master status is determined as idle, the boot core is powered off.
