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.

A single-wire peer-to-peer (P2P) bus apparatus is provided. The single-wire P2P bus apparatus includes a first peer device and a second peer device(s) coupled to a single-wire bus that correspond to a first bus access priority and a second bus access priority(s), respectively. Any of the first peer device and the second peer device(s) can contend for access to the single-wire bus by asserting a bus contention indication(s) when the single-wire bus is in a defined bus state. A winner for the single-wire bus may be a peer device having a highest bus access priority among those peer devices asserting the bus contention indication(s). In this regard, any peer device on the single-wire bus can have a chance to initiate communications over the single-wire bus, thus making it possible for the single-wire bus to function based on bidirectional P2P bus architecture capable of supporting more application and/or deployment scenarios.

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.

An envelope tracking (ET) amplifier apparatus is provided. The ET amplifier apparatus includes an ET integrated circuit (ETIC) and a distributed ETIC (DETIC) coupled to a single-wire bus that correspond to a first bus access priority and a second bus access priority, respectively. The ETIC and the DETIC can contend for access to the single-wire bus by asserting a bus contention indication(s) when the single-wire bus is in a defined bus state configured to permit bus contention. In a non-limiting example, a winner for the single-wire bus is a peer device having a highest bus access priority between the ETIC and the DETIC. In this regard, each of the ETIC and the DETIC can have a chance to initiate communications over the single-wire bus, thus making it possible for the single-wire bus to function based on bidirectional peer-to-peer (P2P) bus architecture capable of supporting more application and/or deployment scenarios.

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.
