Controlling temperature of multiple domains of a multi-domain processor using a cross domain margin

In one embodiment, the present invention includes a method for determining, in a controller of a multi-domain processor, whether a temperature of a second domain of the multi-domain processor is greater than a sum of a throttle threshold and a cross-domain margin, and if so, reducing a frequency of...

description	In one embodiment, the present invention includes a method for determining, in a controller of a multi-domain processor, whether a temperature of a second domain of the multi-domain processor is greater than a sum of a throttle threshold and a cross-domain margin, and if so, reducing a frequency of a first domain of the multi-domain processor by a selected amount. In this way, a temperature of the second domain can be allowed to reduce, given a thermal coupling of the domains. Other embodiments are described and claimed.
