Abstract: A multi-cluster system having processor cores of different energy efficiency characteristics is configured to operate with high efficiency such that performance and power requirements can be satisfied. The system includes multiple processor cores in a hierarchy of groups. The hierarchy of groups includes: multiple level-1 groups, each level-1 group including one or more of processor cores having identical energy efficiency characteristics, and each level-1 group configured to be assigned tasks by a level-1 scheduler; one or more level-2 groups, each level-2 group including respective level-1 groups, the processor cores in different level-1 groups of the same level-2 group having different energy efficiency characteristics, and each level-2 group configured to be assigned tasks by a respective level-2 scheduler; and a level-3 group including the one or more level-2 groups and configured to be assigned tasks by a level-3 scheduler.

Abstract: A switching method for context migration among a plurality of physical processor cores is provided. Each of the physical processor cores is mapped to a corresponding logical processor core. The switching method includes migrating a processor hardware context from a first physical processor core to a second physical processor core which is different from the first physical processor core. The first physical processor core and the second physical processor core are mapped to a first logical processor core and a second logical processor core which is different from the first logical processor core, respectively prior to the migration. The switching method further includes remapping the first physical processor core to the second logical processor core and remapping the second physical processor core to the first logical processor core.
