DISTRIBUTION OF TASKS AMONG ASYMMETRIC PROCESSING ELEMENTS

摘要

Techniques to control power and processing among a plurality of asymmetric cores. In one embodiment, one or more asymmetric cores are power managed to migrate processes or threads among a plurality of cores according to the performance and power needs of the system.

主权项

1. A multi-core processor comprising:
a first processing core and a second processing core, each including one or more arithmetic logic units and an instruction decoder; wherein the first processing core is capable of operating at a higher processing throughput than that of the second processing core; wherein, in response to an occurrence of an event, a task processed on the first processing core is to be transferred from the first processing core to the second processing core after saving a core state of the first processing core and providing the core state to the second processing core; and wherein the first processing core is to be placed in a lower power state after the second processing core resumes processing the task.
