Abstract
An apparatus for providing fault resilience has storage for providing a plurality of compare data blocks, and processing circuitry that performs, for each compare data block, a processing operation using the input data and the compare data block to produce a match condition indication for that compare data block. Performance of the processing operation for each compare data block should result in only one match condition indication indicating a match. Evaluation circuitry evaluates the match condition indications produced for the plurality of compare data blocks and is arranged, in the presence of only one match condition indication indicating a match, to perform a false hit check procedure in order to check for presence of a false hit. In the presence of the false hit, the evaluation circuitry produces an error indication as the outcome indication, but otherwise produces a hit indication as the outcome indication.
