- Abstract
- An apparatus and method for detecting the fault of a processor are disclosed. The apparatus includes a fetch fault control unit, a decoding fault control unit, and an execution fault control unit. The fetch fault control unit detects the fault of each of fetch units of a plurality of processor cores connected to memory. The decoding fault control unit detects the fault of each of decoding units of the plurality of processor cores connected to the memory. The execution fault control unit detects the fault of each of execution units of the plurality of processor cores connected to the memory, executes the same instruction in the plurality of processor cores, determines a processor core where a fault has occurred, and provides notification of the determined processor to the fetch fault control unit and the decoding fault control unit.
