Increasing turbo mode residency of a processor

摘要

In one embodiment, the present invention includes a method for accessing a task stored in an entry of a task queue that identifies the task and a first core of a processor on which the task has been scheduled, reassigning the task to a coldest idle core of the processor, and sending the task to the coldest idle core and maintaining the processor in a turbo mode. Other embodiments are described and claimed.

主权项

1. A processor comprising:
a plurality of cores each to execute instructions, each of the plurality of cores including at least one front end unit, at least one execution unit and at least one cache memory; a mapping table including a plurality of entries each to store a mapping of an advanced programmable interrupt controller (APIC) identifier (ID) to a core of the plurality of cores; and a power control unit (PCU) coupled to the plurality of cores and the mapping table and to access a task queue including a plurality of entries each to store a task identifier for a task and a corresponding identifier for a core on which the task is scheduled, wherein the PCU is to reassign a first task obtained from the task queue from a first core to a second core.
