Abstract
An integrated circuit includes a plurality of data processing circuits that perform an identical processing operation and a judging circuits that judges a consistency or an inconsistency among processing results of the plurality of data processing circuits. A processing error that is generated in any of the plurality of data processing circuits is detected based on a judgment of inconsistency among the processing results provided by the judging circuit.
Claims21
An integrated circuit comprising:
- a plurality of data processing circuits that each performs an identical processing operation;
- and
- a judging circuits that judges a consistency or an inconsistency among processing results of the plurality of data processing circuits,
- wherein a processing error that is generated in any of the plurality of data processing circuits is detected based on a judgment of inconsistency among the processing results provided by the judging circuit.
An integrated circuit comprising:
- a plurality of data processing circuits that each performs an identical processing operation;
- and
- a majority decision circuits that makes a majority decision based on processing results of the plurality of data processing circuits,
- wherein a processing error that is generated in any of the plurality of data processing circuits is corrected by a majority decision result from the majority decision circuit.
5 The integrated circuit according to claim 1, wherein the data processing circuits are memory circuits.
An integrated circuit comprising:
- means for performing a plurality of identical processing operations;
- and
- means for judging a consistency or an inconsistency among processing results from the means for performing a plurality of identical processing operations,
- wherein a processing error that is generated by the means for performing a plurality of identical processing operations is detected based on a judgment of inconsistency among processing results provided by the means for judging.
An integrated circuit comprising:
- means for performing a plurality of identical processing operations;
- and
- means for making a majority decision based on processing results from the means for performing a plurality of identical processing operations,
- wherein a processing error that is generated by the means for performing a plurality of identical processing operations is corrected by a majority decision result from the means for making a majority decision.
A method for providing redundancy in an integrated circuit comprising:
- performing a plurality of identical processing operations;
- judging a consistency or inconsistency in processing results of the plurality of identical processing operations;
- and
- detecting a processing error that is generated in any of the plurality of identical processing operations based on a judgment of inconsistency in the processing results.
