More Information
Summary:A processor includes an accumulator, a storage that outputs data to the accumulator, an error detector that outputs a first error detection signal upon detecting an error in the data, an error identifier that outputs an error identification signal indicating that an error occurs in the storage, an error identification signal holder that outputs the error identification signal as a second error detection signal, an error detection signal holder that holds the first error detection signal and outputs a cancellation signal to stop the accumulation processing of the accumulator, a first calculator that starts making a first calculation based on the second error detection signal and the cancellation signal, and outputs a correction start signal after a lapse of a calculation period, and an error corrector that corrects the error of the data upon receiving the correction start signal.
