Method and system for extending the lifetime of multi-core integrated circuit devices
Abstract:
Embodiments of a method and system are disclosed. One embodiment of an integrated circuit device is disclosed. The integrated circuit device includes first and second processor cores configured to perform a respective first and second set of functional processing. The integrated circuit device also includes a core-specific process state monitor associated with the first processor core, a core-specific process state monitor associated with the second processor core, a core-specific aging monitor associated with the first processor core, a core-specific aging monitor associated with the second processor core, a power management unit, a clock generation unit, and a control system configured to individually control operating points of the first and second processor cores and workload in response to feedback from the core-specific process state monitors and from the core-specific aging monitors.
