The disclosure relates to a method for serially transmitting a frame from a transmitter to at least one receiver via a bus line, as well as a subscriber station for a bus system. According to said method, stuff bits for generating additional signal edges are inserted into the frame by the transmitter according to a predetermined rule, and the stuff bits are removed again by the receiver when evaluating a received frame, a CRC calculation logic of a CRC generator calculating a CRC checksum that is comprised by said frame, and a value of '1' being inserted into said CRC calculation logic in an additional evaluation step if a value of '0 . . . 0' has been determined for the CRC checksum in the running calculation executed by the CRC calculation logic.

A circuit arrangement for a data processing system is configured to process data in a plurality of modules. The circuit arrangement is configured such that each module is provided with at least one clock pulse, a time base and a base of at least one additional physical variable. The circuit arrangement also comprises a central routing unit to which the plurality of modules are coupled and via which the plurality of modules can periodically exchange data amongst themselves, based on the time base and/or the base of other physical variables. Each module is configured independently and parallel to other modules of the plurality of modules in order to process data. The circuit arrangement is employed in a corresponding method.

A companion chip for a microcontroller has a microprocessor bus domain and a peripheral module bus domain, which are connected to each other via a bus bridge. The microprocessor bus domain includes at least one microprocessor core, and the peripheral module bus domain includes at least one global time-management module as well as modules for communication with the outside world and for signal processing. The companion chip further includes at least one FIFO module for transmitting data within the chip, and between the chip and the microcontroller, and a management module connected to the FIFO module, which ensures the consistency of the data by associating a respective time value and/or an angle of rotation.
