Method for operating a data processing system

A method for operating a data processing system for processing data, wherein the data processing system is set up for the repeated execution of a plurality of data processing tasks, wherein:

• a time grid with a clock pulse is provided for the execution of the individual data processing tasks;
• a predetermined repetition rate is specified for each data processing task, wherein each of the repetition rates define a repetition clock pulse which corresponds in each case to an integer number of clock pulses of the grid;
• the repetition clock pulse of the data processing task with a highest repetition rate corresponds to the clock pulses of the time grid;
• data processing tasks build on one another, so that at least one of the data processing tasks processes output data of a further one of the data processing tasks as input data;
• a number of buffer memories are provided, which are assigned to the clock pulses of the time grid and are available in turn, so that output data generated during a respective clock pulse of the clock pulses are written to a respective buffer memory of the buffer memories and output data generated during previous clock pulses continue to be available in others of the buffer memories for a number of clock pulses;
• wherein the following steps are carried out for the operation of the data processing system:
• a) executing each of the data processing tasks at its respective repetition rate in the time grid;
• b) outputting output data by individual ones of the data processing tasks into the buffer memory assigned to the clock pulse of the grid;
• and
• c) reading in input data by individual ones of the data processing tasks from the buffer memories which are assigned to the preceding clock pulses of the grid.
