Abstract
An apparatus includes memory, a processor coupled to the memory, and a set of one or more frequency target monitors. The processor includes a set of one or more processor cores, and the set of one or more frequency target monitors are coupled to the set of one or more processor cores. Each frequency target monitor is configured to determine a difference between an actual performance and an expected performance of a processor core from the set of one or more processor cores. Each frequency target monitor is also configured to, responsive to determining the difference between the actual performance and the expected performance of the processor core from the set of one or more processor cores, record an indication of a difference between the actual performance and the expected performance of the processor core from the set of one or more processor cores.
