PROCESSOR CAPABLE OF FAULT DETECTION AND METHOD OF DETECTING FAULT OF PROCESSOR CORE USING THE SAME

摘要

A processor core capable of detecting an error and a method for preventing an error in processor cores are disclosed. The processor includes: a first processor core which includes one or more pipeline registers; a second processor core which has the same structure as the first processor core and is included in a single chip along with the first processor core; a comparator which compares a value of a pipeline register of the first processor core with a value of a pipeline register of the second processor core; and an error manager which performs an error management operation if it is determined that an error has occurred as a result of the comparison of the comparator.
