20090268744 | Gateway for Data Transfer Between Serial Buses - A gateway for data transfer between serial buses, including multiple communication modules that are each provided for connection of one serial bus, and that carry out a conversion between data packets and data words, a bus master that, via an internal control bus, controls a word-based transfer of data via an internal data bus between two communication modules, the bus master applying a source address via a source address bus to an internally transmitting first communication module, and a destination address via a separate destination address bus to an internally receiving second communication module, data received in data packets by the first communication module via a first serial bus connected thereto being transferred from the first communication module directly without buffering, in word-based fashion in one or more data words, via the internal data bus to the second communication module, which delivers these transferred data, in data packets, via a second serial bus connected to the second communication module. | 10-29-2009 |
20090292844 | Multiprocessor gateway - A multiprocessor gateway for multiple serial buses includes: multiple communication modules that are each provided for connection of one serial bus; multiple processors for processing data that are transferred in word-based fashion, via an internal system bus appurtenant to the respective processor, between the processor and the communication modules, the internal system buses of the multiprocessor gateway being connected to the communication modules, which have a respective appurtenant interface unit for each system bus, each processor exchanging data, via its appurtenant system bus and the interface unit, appurtenant to the system bus, of a communication module, with the serial bus connected to the communication module, independently of the other processors and without waiting time. | 11-26-2009 |
20090323708 | Subscriber and Communication Controller of a communication System and Method for Implementing a Gateway Functionality in a Subscriber of a Communication System - A subscriber of a communication system includes a microprocessor, at least two communication controllers and a peripheral bus. The microprocessor is connected to the communication controllers via the peripheral bus and is also connected via the communication controllers respectively to a communication link of the communication system, via which messages are transmitted. In order to optimize the gateway functionality within the subscriber, a provision is made that at least one of the communication controllers has an active interface via which the communication controller is connected to the peripheral bus and has a logic circuit for independently implementing a gateway functionality. | 12-31-2009 |
20100064082 | COMMUNICATION MODULE - A communication module for connecting a serial bus, which transmits data in packets, to a plurality of system buses of a gateway, which transmit data word by word, the communication module having a communication protocol unit, which is connected to the serial bus, for converting between data packages and messages, which are respectively made up of a plurality of data words, a message relaying unit for relaying messages between at least one message memory and the communication protocol unit, as well as buffer memories, a plurality of interface units, which are respectively connected to an associated system bus of the gateway, each interface unit being connected to at least one associated buffer memory, which stores a message temporarily, a transmission of data words via a plurality of system buses and their associated interface units from and to the buffer memories of the interface units taking place simultaneously, without delay. | 03-11-2010 |
20110167188 | SUBSCRIBER NODE OF A COMMUNICATION SYSTEM HAVING A FUNCTIONALLY SEPARATE TRANSMISSION EVENT MEMORY - A subscriber node of a communication system, a communication system and a method for transmitting a message in the communication system. The message is transmitted from a first subscriber node of the communication system via a data bus of the communication system to a second subscriber node of the communication system. An application program of the first subscriber node files the message, that is to be sent, in a message memory, from where it is retrieved by a communication controller, upon a sending command of the application program, and is transmitted via the data bus. In particular in the case of a cancellation of the transmission job, in order to be able to improve the capacity utilization and the efficiency of a host CPU, it is provided that a transmission event for the message, that is to be sent or that has been sent, is stored in at least one transmission event memory, that is functionally separate from the message memory, and that the application program is able to access the data stored in the event memory at any time. | 07-07-2011 |
20130103811 | METHOD FOR PROVIDING A COMMUNICATION FOR AT LEAST ONE DEVICE - A method for providing a communication for at least one device that is provided for a motor vehicle and is linked via a network of the motor vehicle to at least one further device, where data between the at least one device and the at least one further device are exchanged via an Internet Protocol. Also a device and a network are provided. | 04-25-2013 |
20130111074 | METHOD FOR CHANGING AN OPERATING MODE OF AT LEAST ONE DEVICE | 05-02-2013 |
20130138750 | METHOD FOR PROCESSING MESSAGES - In a method for processing messages with the aid of at least one Ethernet controller having a message store, the at least one Ethernet controller checks a received message for the presence of at least one property, and the received message is stored in the message store if this at least one property applies to the message. | 05-30-2013 |
20130297783 | NETWORK - In a having a plurality of levels, each level has at least one information node; a number of information nodes of a lower k+1-th level are assigned to an information node of a k-th level configured thereabove and linked to this one information node; one information node of the lower k+1-th level is designed to inform the information node of the k-th level configured thereabove, which pieces of information the information node of the k+1-th level needs, and which pieces of information the information node of the k+1-th level is making available. | 11-07-2013 |
