Abstract
The present invention discloses a method and an apparatus for recovering abnormal data in an internal memory. The method includes: receiving, by a processor, a data abort signal and an address of an abnormal instruction where abnormal data is located; suspending a current instruction being executed, and recording an address pointed to by a computer pointer; obtaining a program unit currently being executed by the processor; if it is determined that the abnormal instruction belongs to the program unit and that instructions between the first instruction and the current instruction in the program unit are all reversible instructions, invoking a destruction program unit corresponding to the program unit, so as to release resources already applied for by the program unit; and causing the computer pointer to point back to an address of the first instruction in the program unit, and re-executing the program unit.
