First Claim
Patent Images
1. A method, comprising:
- determining an amount of wear in a computing system over time;
calculating a number of accumulated credits for the computing device based on the determined amount of wear;
adjusting operating conditions in the computing system based on the number of accumulated credits; and
operating the computing system under adjusted operating conditions.

Abstract
Embodiments of the claimed subject matter are directed to methods and systems that allow tracking and accounting of wear and other aging effects in integrated circuits and products which include integrated circuits over time, and the dynamic adjustment of operating conditions to increase or decrease wear in response to the accumulated wear relative to the expected wear during the lifetime of the circuit and/or product.

30. A computing system comprising:
-
a processor configured to process programmed instructions in the computing system at a plurality of frequencies; a power supply device configured to supply power to the computing system at a plurality of voltages; and a plurality of integrated circuits that accumulates wear over time during operation of the computing system, wherein the computing system accumulates a plurality of operating credits while the computing system operates at a performance level under a pre-determined threshold and consumes operating credits while the computing system operates at a performance level above the pre-determined threshold, wherein the performance level corresponds to at least one of a voltage supplied by the power supply device, a processor frequency in the computing system, and a junction temperature of a component in the computing system further wherein, the computing system is further operable to operate at a performance level above the pre-determined threshold for so long as a surplus of the operating credits remains. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37)
