Abstract
In one embodiment, a processor includes multiple cores and a power control unit (PCU) coupled to the cores. The PCU has a stress detector to receive a voltage and a temperature at which the processor is operating and calculate lifetime statistical information including effective reliability stress, maintain the lifetime statistical information over multiple boot cycles of a computing system such as personal computer, server computer, tablet computer, smart phone or any other computing platform, control one or more operating parameters of the processor based on the lifetime statistical information, and communicate at least a portion of the lifetime statistical information to a user and/or a management entity via an interface of the processor. Other embodiments are described and claimed.
