A link controller includes a Peripheral Component Interconnect Express (PCIe) physical layer circuit for coupling to a communication link and providing a data path over the communication link, a first data link layer controller which operates according to a PCIe protocol, and a second data link layer controller which operates according to a non-PCIe protocol. A multiplexer-demultiplexer selectively connects both data link layer controllers to the PCIe physical layer circuit. A protocol translation circuit is coupled between the multiplexer-demultiplexer and the second data link layer controller, the protocol translation circuit receiving traffic data from the second data link layer controller in a non-PCIe format, encapsulating the non-PCIe format in a PCIe format, and passing traffic data to the multiplexer-demultiplexer circuit.

A device for a serial bus system. The device includes a reception block for receiving a signal from a bus of the bus system. The signal is based on a transmission signal via which a message is exchanged between user stations. The reception block receives, in a first communication phase, the signal using a first reception threshold, and in a second communication phase, receives the signal using a second reception threshold. The device includes an evaluation block for evaluating the signal from the bus using a switchover reception threshold that differs from the first and second reception thresholds, and a reception threshold switching block for the time-limited switchover of the reception threshold of the reception block from the first reception threshold to the second reception threshold when the evaluation block detects the bus level for data of the transmission signal, using the switchover reception threshold in the signal.

Disclosed are a module assembly and a multi-master communication method thereof, and more particularly, a module assembly including a plurality of modules capable of transmitting/receiving data by forming an open drain based one-wire communication bus upon mutual combination, in which at least one module requiring the data transmission among the plurality of modules performs first declaration for a transmission intention by outputting a low signal within a predetermined first arbitration time when at least one module is in an on state by sensing the one-wire communication bus state, at least one module performing the first declaration for the transmission intention performs second declaration for the transmission intention by outputting a high signal within a second arbitration time, and a module which outputs the high signal last within the second arbitration time secures final bus occupation.

A device for a serial bus system. The device has a receiver receiving a signal from a bus of the bus system. For a message exchanged between user stations of the bus system, a recessive bus state is overwritable by a dominant bus state and the recessive bus state is generated differently in the first communication phase than in the second communication phase. The receiver generates a digital signal based on the received signal, and the signal being output to a communication control unit for evaluating the data contained in the digital signal. The receiver uses a first and second reception threshold for generating the digital signal in the second communication phase, the second reception threshold having a voltage value lower than that of the first reception threshold or higher than the highest voltage value which, during normal operation, is established on the bus for a dominant bus.

An extension of the existing CAN FD data transmission protocol. The extension enables the use of the IPv6 protocol for the CAN bus. The CAN FD protocol is further developed in an incompatible way. One modification measure relates to the lengthening of the Data Field, which is positioned in the transmission frame after an Arbitration Field. An arbitrary number of bytes can be entered in the extended Data Field within a specified upper limit. Since the Data Field is transmitted at a higher bit rate field than the Arbitration Field, the data throughput is increased dramatically.

A first operation identifier is assigned to a current operation directed to a memory component, the first operation identifier having a first entry in a first data structure that associates the first operation identifier with a first buffer identifier. It is determined whether the current operation collides with a prior operation assigned a second operation identifier, the second operation identifier having a second entry in the first data structure that associates the second operation identifier with a second buffer identifier. A latest flag is updated to indicate that the first entry is a latest operation directed to an address (1) in response to determining that the current operation collides with the prior operation and that the current and prior operations are read operations, or (2) in response to determining to determining that the current operation does not collide with a prior operation.

Subscriber-stations for a bus-system, and data-transmission method in a bus-system. The subscriber-stations include master-subscriber-station(s) and at least two slave-subscriber-stations for the bus-system. The master-subscriber-station includes a first-transceiver-device for sending/receiving a message to/from at least one slave-subscriber-station that is subordinate control-wise to the master-subscriber-station, via a first-sub-bus of the bus-system, a second-transceiver-device for sending/receiving a message to/from at least one other subscriber-station, via a second-sub-bus of the bus-system, a communication-control-device for creating the message to be sent or for evaluating a message received from one of the sub-buses of the bus-system, and a linking-device for linking a terminal of the first-transceiver-device that is for outputting of a signal generated from the message received from the first-sub-bus and a terminal of the second-transceiver-device for outputting a signal generated from the message received from the second-sub-bus, so that only one signal is forwarded, as a receive-signal, to a communication-control-device terminal.
