Abstract: Error-correcting circuit includes: component generating a first output from first and second inputs; error detector generating an error flag indicative of whether or not an error is detected in the first output, based on the first output, and the first and second inputs; correction generator generating a correcting output after a first time period beginning with a timing event, based on the first output, and the first and second inputs; and output generator generating an output after a second time period beginning with the timing event. If the error flag indicates a detected error then the second time period may be longer than the first time period, otherwise it may be not longer, and the error-correcting circuit output may include a combination of the first output and the correcting output whereby the detected error is corrected, otherwise the error-correcting circuit output may correspond directly to the first output.

Abstract: An error-correcting circuit comprises: a component arranged to generate a first output from a first input and a second input; an error detector arranged to generate an error flag indicative of whether or not it has detected an error in the first output, based on the first output, the first input and the second input; a correction generator suitable for generating a correcting output after a first time period beginning with a timing event, based on the first output, the first input and the second input; and an output generator arranged to generate an output of the error-correcting circuit after a second time period beginning with the timing event. If the error flag indicates that an error has been detected in the first output then the second time period may be longer than the first time period, otherwise the second time period may be not longer than the first time period.
