Apparatus and method for detecting fault of processor

It proposes an apparatus and method for detecting a failure of a processor that can detect and correct the error by internal units of the processor. The proposed apparatus decodes error control unit for detecting an error of the plurality of processors fetch for detecting an error of each of the fetch unit in the core error control unit, a plurality of processor cores, each of the decoding unit in the access to a memory connected to the memory, and a memory It includes an execution error controller informs the same commands and detecting errors in each of the execution units in the plurality of processor cores connected to a plurality of to and run in the processor core to determine the processor core that generated the error it fetches an error control and decodes error control do.
