Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A dynamic power management method of a multi-core processor system, adapted to a processor system applying a multi-core processor, the multi-core processor comprising a boot core and at least one slave core, and steps of the method comprising: obtaining a workload of the multi-core processor during a runtime stage; performing a hot-plug operation on the at least one slave core respectively according to the workload and a working state of the at least one s…
