主权项

1. An apparatus comprising:
a first core susceptible to an error condition; a second core configured to perform, in response to a detection of the error condition:
a diagnostic on the first core by directly communicating with the first core to identify a cause of the error condition, andan action to remedy the error condition to recover the first core; a third core configured to operate as the first core when the first core is associated with the error condition; and a core repair engine, which is separate from the first, second, and third cores, configured to facilitate repairing or recovering the error condition associated with the first core by communicating directives to the second core, wherein the third core is further configured to operate as the first core and the first core is configured to operate as a spare subsequent to the recovery of the first core via the action.
