1. An apparatus comprising:
interface circuitry;
computer readable instructions; and
at least one processor circuit to be programmed based on the computer readable instructions to:
partition a plurality of cores of a microprocessor into subsets of cores including a first subset of cores and a second subset of cores;
access information that specifies a target lifespan of the microprocessor;
determine a threshold period of time based on the target lifespan, the threshold period of time less than the target lifespan; and
periodically switch at intervals of the threshold period of time between (i) a first state with the first subset of cores active and with the second subset of cores inactive, and (ii) a second state with the second subset of cores active and with the first subset of cores inactive.
