Data processing network for performing data processing

A data processing network for a redundant and validated carrying out of a plurality of successive data processing step, each of which is used to generate output data from input data, output data of a first data processing step being at least partially simultaneously input data of a further data processing step, the data processing network comprising:

• at least a first data processing module and a second data processing module, each configured to carry out each of the data processing steps;
• and
• a comparator module, the first data processing module and the second data processing module being configured to transmit control parameters of the data processing steps to the comparator module, and the comparator module being configured to carry out at least one comparison of corresponding control parameters that were transmitted by the first data processing module and the second data processing module and, based on the comparison, to provide at least one synchronized control parameter that contains an item of control information relating to at least one data processing step that has been carried out.

A method for operating a data processing network, comprising the following steps:

• a) carrying out a data processing step with a first data processing module and generating a first control parameter that is suitable for checking the carrying out of the data processing step with the first data processing module;
• b) independently of step a), carrying out the same data processing step with a second data processing module and generating a second control parameter that is suitable for checking the carrying out of the data processing step with the second data processing module;
• c) carrying out, with a comparator, a comparison of corresponding control parameters that were transmitted by the first data processing module and the second data processing module, and, based on the comparison, providing at least one synchronized control parameter that contains an item of control information relating to at least one data processing step that was carried out.
