ABSTRACT:
A method for transferring at least one data record from an external data source into a processor unit, e.g., and a suitably designed processor unit are described. In such a method for transcribing at least one data record from the external data source to a processor unit, the at least one data record is transmitted from the external data source together with additional information to a buffer memory of the process unit. A check of the admissibility of using the at least one data record is performed on the basis of the additional information. A blocking signal is generated when the check reveals that use of the at least one data record is not allowed. The at least one data record is then deleted from the buffer memory. An enable signal is generated when the use of the at least one data record is allowed. The additional information includes an identifier assigned individually to the processor unit, with the validity check being performed in the processor unit.
