method for operating a real-time critical application on a control unit

A non-transitory computer-readable data storage medium storing a computer program having program codes which, when executed on a computer, perform a method for operating a real-time critical application, having at least two operating modes, on a control unit of a motor vehicle having at least two parallel processor cores or microprocessors, the method comprising:

• reading out, from a memory assigned to the control unit, configuration data assigned to a selected operating mode of the at least two operating modes, wherein the configuration data include information concerning at least one of (i) the ability of task lists assigned to the selected operating mode to be executed on each of the at least two parallel processor cores or microprocessors, and (ii) which of the processor cores or microprocessors is to be used for the selected operating mode;
• determining, on the basis of the read configuration data, which of the at least two parallel processor cores or microprocessors are necessary to operate the real-time critical application and which of the at least two parallel processor cores or microprocessors are one of able to be switched off or operated in an energy-saving mode;
• and
• reading out and activating task lists assigned to the selected operating mode, from the memory assigned to the control unit.
