Abstract:
In one embodiment, the present invention includes a method for determining that a non-core domain of a multi-domain processor is not operating at a frequency requested by the non-core domain, sending a request from the non-core domain to a power controller to reduce a frequency of a core domain of the multi-domain processor, and responsive to the request, reducing the core domain frequency. Other embodiments are described and claimed.
