Multi-core processor system implementing migration of a task from a group of cores to another group of cores

摘要

A multi-core processor system includes a core configured to detect among multiple cores, a state of migration of first software from a first core to the core whose specific processing capacity value is lower than that of the first core; and set the processing capacity value of the first core at a time of the detection to be a processing capacity value that is lower than that before the migration when detecting the state of migration.

主权项

1. A multi-core processor system comprising:
a first core group comprising a plurality of first cores processing an event; a second core group comprising a plurality of second cores, a number of the plurality of second cores included in the second core group being the same as a number of the plurality of first cores included in the first core group, the plurality of second cores having a lower maximum processing capacity value for processing the event than the plurality of first cores; a storage storing migration event information showing an event that enables migration from the first core group to the second core group; and one or more processors configured to:
detect an allocation of a migration event corresponding to the migration event information in the first core group;start a second operating system associated with the second core group and cause a first operating system associated with the first core group to end;migrate the migration event assigned to a first core included the first core group to an arbitrary second core included in the second core group; andset a processing capacity value of the first core group after the migration event has migrated to be a processing capability value lower than a processing capability value before the migration event has migrated.
