  • High speed Hamming code circuit and method for the correction of error bursts
    Patent number: 4276647
    Abstract: A circuit and method for the high speed generation and comparison of Hamming codes to enable the correction of an error burst is described. The circuit generates or compares n Hamming codes simultaneously with the data field transmission. Each code word is associated with a data field word comprising every n.sup.th bit. The resultant system corrects error bursts of up to n bits.Additional circuitry is included to enable the correction of error bits in parallel, increasing the system bandwidth.
