Self-checking error checker for kappa-out-of-nu coded data
Abstract
Abstract A SERIES OF SELF-CHECKING ERROR CHECKING CIRCUITS ARE DISCLOSED FOR CHECKING K-OUT-OF-N CODED DATA LINES. THE N LINES ARE BROKEN INTO TWO, PREFERABLY EQUAL, GROUPS. A LOGIC EQUATION IS DERIVED FOR EACH GROUP OF LINES WHEREBY, WITH ANY K-OUT-OF-N CODED DATA SIGNALS APPLIED TO THE INPUT, AT LEAST TWO COMPLEMENTARY OUTPUT SIGNALS ARE PRODUCED. ANY ERROR APPEARING IN THE RECEIVED CODE WILL BE INDICATED AS SUCH BY NON-COMPLEMENTARY OUTPUTS FROM THE CHECKER IN THE OUTPUT OF THE CHECKER. MALFUNCTIONS OR FAILURES IN THE CHECKING CIRCUIT ARE CHECKED BY CERTAIN LEGITIMATE CODE SIGNALS WHICH SIMILARLY CAUSE AN ERROR REPRESENTATION IN NON-COMPLEMENTARY OUTPUTS AT THE OUTPUT OF THE CHECKER.
