ABSTRACT:
Disclosed is a design structure for an associated first system for extending product life of a second system in the presence of phenomena that cause the exhibition of both performance degradation and recovery properties within system devices. The first system includes duplicate devices incorporated into the second system (e.g., on a shared bus). These duplicate devices are adapted to independently perform the same function within that second system. Reference signal generators, a reference signal comparator, a power controller and a state machine, working in combination, can be adapted to seamlessly switch performance of that same function within the second system between the duplicate devices based on a measurement of performance degradation to allow for device recovery. A predetermined policy accessible by the state machine dictates when and whether or not to initiate a switch.
