Abstract
Systems and methods are presented for reducing the impact of high load and aging on processor cores in a processor. A Power Management Unit (PMU) can monitor aging, temperature, and increased load on the processor cores. The PMU instructs the processor to take action such that aging, temperature, and/or increased load are approximately evenly distributed across the processor cores, so that the processor can continue to efficiently process instructions.
