Abstract
In an embodiment, a processor includes a first domain with at least one core to execute instructions and a second domain coupled to the first domain and including at least one non-core circuit. These domains can operate at independent frequencies, and a power control unit coupled to the domains may include a thermal logic to cause a reduction in a frequency of the first domain responsive to occurrence of a thermal event in the second domain. Other embodiments are described and claimed.
