Method of operating a processor-controlled system
When reading stored data, a check sum (PS) is formed by summation of the data words (DW) from one data region (DB). Using an algebraic operation, a check word (PW) is generated from the check sum, and compared with the read-out check word associated with the data region. If there is a deviation betw...

| Zusammenfassung: | When reading stored data, a check sum (PS) is formed by summation of the data words (DW) from one data region (DB). Using an algebraic operation, a check word (PW) is generated from the check sum, and compared with the read-out check word associated with the data region. If there is a deviation between them, an error is detected in the stored data. |
