Abstract
A first circuitry may be configured to generate a first output based on an input and send an indication responsive to detection of an error while the first output is generated. A second circuitry may be configured to generate a second output based on the input. A wrapper circuitry may be configured to compare the first output and the second output to check correctness by default, and responsive to receipt of the indication, select the second output as a system output without checking for correctness by comparing the first output and the second output. In some implementations, the second circuitry may be configured to send a second indication responsive to detection of a second error while the second output is generated. The wrapper circuitry may be configured to, responsive to receipt of the second indication, ignore the check for correctness.
