Abstract: A processor has a limited set of guard bands that the processor uses, and when a certain amount of stress is accumulated as indicated by the cumulative stress counters (Seff), and the threshold for the current guard is about to be exceeded, the processor switches to the next wider guard band with this technique occurring until all the guard bands are used and end of life settings are reached. This data that can be stored in the FPFs, and in accordance with one exemplary embodiment, the guard band index itself is also stored in the FPFs and used to ensure the most accurate guard band is used by the processor/device.
