Aspects of the present disclosure relate to an apparatus comprising processing circuitry to
execute a plurality of code sequences, and configuration storage to store mode control data
for the processing circuitry. When the processing circuitry is executing one of said plurality of
code sequences, the mode control data is set so as to identify a high resilience mode of
operation of the processing circuitry where usage of one or more components of the
processing circuitry is modified so as to increase resilience of the processing circuitry to …

An apparatus and method are provided for increasing resilience to faults. The apparatus
comprises processing circuitry for executing a plurality of code sequences including at least
one critical code sequence, and configuration storage for storing mode control data for the
processing circuitry. When the processing circuitry is executing a critical code sequence, the
mode control data is set so as to identify a high resilience mode of operation of the
processing circuitry, where usage of one or more components of the processing circuitry is …
