摘要:
In one embodiment, a processor includes a core with a front end unit, at least one execution unit, and a back end unit. Multiple voltage drop detectors can be located within the core each to output a voltage drop signal when a detected voltage falls below a threshold voltage. In turn, a current transient logic coupled to receive the voltage drop signals can control a micro-architectural parameter of at least one of the front end unit, execution unit and back end unit responsive to receipt of a voltage drop signal. Other embodiments are described and claimed.

Methods and apparatus relating to power management for multiple processor cores are described. In one embodiment, one or more techniques may be utilized locally (e.g., on a per core basis) to manage power consumption in a processor. In another embodiment, power may be distributed among different power planes of a processor based on energy-based considerations. Other embodiments are also disclosed and claimed.

Methods and apparatus relating to deterministic management of dynamic thermal response of processors are described. In one embodiment, available thermal headroom may be used to extract the performance potential in a deterministic way, e.g., such that it reduces or even eliminates the product-to-product variations. Other embodiments are also disclosed and claimed.

In one embodiment, a processor includes a plurality of cores and a power controller including a first logic, responsive to a determination that the processor resided in a forced idle state for less than a threshold duration, to update a first counter and, responsive to a value of the first counter that exceeds a control threshold, prevent the processor from entry into the forced idle state. Other embodiments are described and claimed.

摘要:
A method for dynamically operating a multi-core processor system is provided. The method involves ascertaining currently active processor cores, identifying a currently active processor core having a lowest operating frequency, and adjusting at least one operational parameter according to voltage-frequency characteristics corresponding to the identified processor core to fulfill a predefined functional mode, e.g. power optimization mode, performance optimization mode and mixed mode.
