Abstract
Apparatus and methods for maintaining approximate uniformity of aging of equivalent processing circuits in a pipeline stage(s) in a processor are disclosed. The processor includes one or more processing units that include one or more pipelines. A pipeline includes a series of pipeline stages each of which performs a particular function. In this regard, the processor also includes an age management circuit (AMC) configured to store performance factors indicative to aging of the equivalent processing circuits in a pipeline stage. In response to work input into a given pipeline stage, the AMC is further configured to route the work input to one of the equivalent processing circuits in the pipeline stage based on the stored performance factors. In so doing, the AMC controls the frequency of use of the equivalent processing circuits in its pipeline stage to substantially maintain uniform aging of the equivalent processing circuits.
