Abstract: A method is provided for classifying a data segment with respect to its further processing in a data transporting unit, in particular in a network processor. The data segment is provided by an input interface. A first key for a lookup table is ascertained as a function of an identifier (chid) established in advance and as a function of an identifier (devid) of the input interface from which the data segment stems. A second key for the lookup table is ascertained.

Abstract: An interface unit is provided for the arrangement between a bus system, to which a processor unit and a data memory are connectable, and a data transporting unit, in particular a network processor, are described. The interface unit carries out a direct memory access to the data memory as a function of an identifier (chid) previously agreed upon between an application and the data transporting unit.

Abstract: A network interface unit includes: at least one input terminal for receiving Ethernet data packets; at least one output terminal; and a segmentation unit configured for (i) segmenting at least one of a received Ethernet data packet and an Ethernet data packet modified by the network interface unit into at least one data segment having a predefined length, and (ii) for outputting the at least one data segment via the output terminal.

Abstract: A method for setting up an array of technical units and such an array are presented. The method is used for the independent setup and operation of an array of technical units, the technical units being connected to one another via a system communication bus, a query for a system resource being transmitted from a querying unit to all other units, all other units checking whether the resource has already been assigned to this unit itself, and all querying units transmitting an appropriate response to the querying units and the system resource being assigned thereto if it is not already assigned to one of the other units.

Abstract: A method for accelerated data transmission among electronic control units (ECUs) and/or measuring devices in the context of motor vehicles is provided. In order to enable an accelerated data transmission, in particular fast (low) event cycle times, a low jitter and a high data throughput, the architecture of the data transmission is split up into (i) a control plane implemented in software operating on configuration, calibration and/or diagnostics data (“CD” data), and (ii) a data plane implemented in hardware transporting measurement data (“M” data) and/or prototyping data (“RP” data).

Abstract: A communications network and corresponding method comprising topology means for detecting the topology of the network means for detecting the timing status of each node and for providing to at least one node of the communications network information on the detected topology of the network and timing status and for selecting a source of timing information on the basis of the information detected.
