Patent number: 7940874Abstract: Receiver for receiving a data stream via a data bus, which receiver samples the bits of the data stream in an over-sampling process, in which n bit strobe offsets are used and n data sets with i bits are sampled,—applies a decision criterion for identifying those data sets with correct bit values. This decision uses checksum CRC,—selects one of the identified data sets with correct bit values and—uses the bit strobe offset, which was used for receiving the selected data streams, for receiving the data stream. In this way the multiphase clock with optimal phase shifts is selected.Type: GrantFiled: April 25, 2006Date of Patent: May 10, 2011Assignee: NXP B.V.Inventors: Peter Fuhrmann, Jörn Ungermann, Manfred Zinke, Klaus Peter May

Patent number: 7848361Abstract: A time-triggered communication system in a dual-channel network of singlechannel architecture, wherein in each case one communication controller (2, 6) is assigned to one channel, and two corresponding communication controllers (2, 6) communicate with one another via an inter-channel interface (1a, 1b). Said inter-channel communication contains information about limiting points (G1, G2 . . . G12) of a time path. A limiting point (G1, G2 . . . G12) is, for example, the point in time when a cycle starts. The interchange of limiting points enables the temporal offset of the two channels to be determined as well as a correction value. After every two cycles also the rate error of the local clocks can be ascertained and a suitable correction value determined. The reliability of safety-relevant networks is increased by the time-triggered communication system described hereinabove.Type: GrantFiled: May 10, 2004Date of Patent: December 7, 2010Assignee: NXP B.V.Inventors: Jörn Ungermann, Peter Fuhrmann

Patent number: 7474625Abstract: A dual-channel network with in each case one communication controller (2, 6) for each of the two channels (A, B). In order to ensure that the two channels (A, B) operate on a temporally matched basis, an exchange of current states (“ready, “abort”) takes place via an external or an on-chip interface (1a, 1b). The cold start operation is carried out only if, and so long as, both communication controllers are in the “ready” state.Type: GrantFiled: May 10, 2004Date of Patent: January 6, 2009Assignee: NXP B.V.Inventors: Jörn Ungermann, Peter Fuhrmann

Publication number: 20060224394Abstract: The invention relates to a method of transmitting user data via a communications medium (2) between subscribers (3) connected to the communications medium (2), wherein the data are transmitted in recurrent cycles (8) and at least one slot (9, 10) in each cycle (8) is intended for the user data of at least one subscriber (3). In order to permit a particularly efficient data transmission via the communications medium (2) at least one of the slots (10) is used to transmit the user data of different subscribers (3) (A, C, F) in different cycles (8). In addition, a bus guardian (6) of one subscriber (3) determines whether the subscriber (3) may transmit user data in the current slot (9, 10) of the current cycle (8), the bus guardian (6) having at least indirect access to a universal condition available throughout the entire communications system (1). In particular, an internal counter of the bus guardian (6) is synchronized to a universal cycle counter.Type: ApplicationFiled: April 26, 2004Publication date: October 5, 2006Inventors: Jorn Ungermann, Peter Fuhrmann, Manfred Zinke

Publication number: 20050141565Abstract: The invention refers to one of a number of nodes of a communication system. The nodes are connected to a communication media for transmitting data among the nodes. Said one node comprises a communication controller, across which the node is connected to the communication media, and a bus guardian for controlling access of the communication controller to the communication media. In order to provide a cheap but nevertheless reliable way for monitoring the synchronized clock signal of a node of a communication system and in particular for detecting deviations of the synchronized clock signal it is suggested that a synchronized clock signal from the communication controller is made available to the bus guardian, and that the bus guardian comprises means for monitoring the synchronized clock signal using a bus guardian internal clock signal, which is generated by means of an electronic circuit and which is less accurate than the synchronized clock signal to be monitored.Type: ApplicationFiled: July 7, 2003Publication date: June 30, 2005Applicants: Robert Bosch GmbH, Daimler Chrysler AG, Bayerische Motoren Werke AG, General Motors Corp., Motorola Inc., Koninklijke Philips Electronics N.V.Inventors: Thomas Forest, Bernd Hedenetz, Mathias Rausch, Christopher Temple, Harald Eisele, Bernd Elend, Jorn Ungermann, Matthias Kuhlewein, Ralf Belschner, Peter Lohrmann, Florian Bogenberger, Thomas Wuerz, Arnold Millsap, Patrick Heuts, Robert Hugel, Thomas Fuhrer, Bernd Muller, Florian Hartwich, Manfred Zinke, Josef Berwanger, Christian Ebner, Harald Weiler, Peter Fuhrmann, Anton Schedl, Martin Peller

Publication number: 20040081193Abstract: Method for transmitting data within a communication system, the communication system comprising a communication media and a number of nodes connected to the communication media, the data being transmitted across the communication media within a communication cycle comprising a number of time slots assigned to one or more nodes of the communication system. In order to provide a possibility for a data transmission within communication cycles, which can satisfy the demands in communication systems for safety critical applications, too, it is suggested, that the communication cycle is initiated by an external event. The external event can be caused by manually setting a bit by a host, by a configurable timer in a controller host interface (CHI) or by an external trigger.Type: ApplicationFiled: July 7, 2003Publication date: April 29, 2004Inventors: Thomas Forest, Bernd Hedenetz, Mathias Rausch, Christopher Temple, Harald Eisele, Bernd Elend, Jorn Ungermann, Matthias Kuhlewein, Ralf Belschner, Peter Lohrmann, Florian Bogenberger, Thomas Wuerz, Arnold Millsap, Patrick Heuts, Robert Hugel, Thomas Fuhrer, Bernd Muller, Florian Hartwich, Manfred Zinke, Josef Berwanger, Christian Ebner, Harald Weiler, Peter Fuhrmann, Anton Schedl, Martin Peller
