Abstract
An apparatus and method for recovering the functionality of central processing unit core are disclosed herein. The apparatus for recovering the functionality of a central processing unit (CPU) core includes a functionality recovery buffer and a functionality recovery module unit. The functionality recovery buffer temporarily stores a value, to be stored in a register storage unit, in response to a write operation. The functionality recovery module unit performs the recovery of functionality by controlling the functionality recovery buffer when receiving a signal, indicating that a failure has been detected, from the outside.
