Abstract

In one embodiment, a processor includes at least one core and an interface circuit to interface the at least one core to additional circuitry of the processor. In response to an in-field self test instruction, at least one core may save state to a low power memory, enter into a diagnostic sleep state and execute an in-field self test in the diagnostic sleep state in which the at least one core appears to be inactive. Other embodiments are described and claimed.
