A method for operating a data processing unit of a driver assistance system, the unit including main and slave computers. The main computer ascertains surroundings data from a surroundings detection system by using a processing specification. The slave computer operates a communication interface of the data processing unit, using a communication instruction. The method includes initializing, a first testing, a carrying out, a second testing and a forwarding. In initializing, the main computer, in response to a signal, is initialized by performing an initialization instruction on the main computer. In the first testing, the slave computer, in response to the signal, is initialized by performing a self-test instruction on the slave computer. In the carrying out, the communication instruction is performed on the slave computer to send and/or receive data via the communication interface, when the slave computer is tested and while the main computer is initialized. In the second testing, the main computer is tested by performing a test instruction on the slave computer, when the main computer is initialized. In the forwarding, the surroundings data are forwarded via the communication interface by performing the communication instruction on the slave computer, when the main computer is tested.

A method is described for checking a hardware-configurable logic circuit including circuit areas and including a configuration memory having different subareas for faults, a respective configuration of hardware elements of one of the circuit areas being defined by configuration data stored in an associated subarea of the configuration memory, and when at least one checking requirement in regard to an output signal which is provided by the hardware-configurable logic circuit is met, a fault check of the configuration data being carried out only in those subareas of the configuration memory of the hardware-configurable logic circuit which are involved in generating the output signal.

A communication system configuration has an annular design and includes multiple participants which are serially interconnected, one participant being configured as a master and the remaining participants being configured as slaves. The master is configured for transmitting a data packet to one or a plurality of slaves, and each slave has a shift register. The communication system includes a participant which has an external interface and is adapted for receiving data via the external interface from outside of the communication system to implement a debugging or a programming of one or a plurality of participants of the communication system or for transmitting data to outside of the communication system.
