发明名称 Providing Per Core Voltage And Frequency Control
摘要 In one embodiment, the present invention includes a processor having a plurality of cores and a control logic to control provision of a voltage/frequency to a first core of the plurality of cores independently of provision of a voltage/frequency to at least a second core of the plurality of cores. In some embodiments, the voltages may be provided from one or more internal voltage regulators of the processor. Other embodiments are described and claimed.

主权项 1. A non-transitory machine-readable medium having stored thereon instructions, which if performed by a machine cause the machine to perform a method comprising: controlling, by a first logic of a multicore processor including a plurality of cores, provision of a voltage/frequency to a first core of the plurality of cores independently of provision of a voltage/frequency to at least a second core of the plurality of cores, the first core and the second core to execute asymmetric workloads, wherein at least one of the plurality of cores includes a decoder to decode instructions, at least one execution unit to execute the decoded instructions, and at least one core-included cache memory, wherein the at least one of the plurality of cores comprises an out-of-order pipeline, the multicore processor further including a shared cache memory, and an integrated memory controller; determining, by the first logic, whether to update the voltage/frequency of the first core based at least in part on a workload and a temperature of the processor, and responsive to the determination, updating the voltage/frequency provided to the first core, including sending a control signal to a voltage regulator to cause the voltage regulator to provide the updated voltage to the first core.
