摘要： Embodiments of the present disclosure provide a connector. The connector includes first to third interfaces, a switch circuit, a power supply device control circuit, and an interface control circuit. The first to third interfaces are configured to connect a host device, an upstream facing port (UFP) device and a power supply device, respectively. The switch circuit is connected to the first interface, the second interface, the third interface, and the interface control circuit. The power supply device control circuit is connected to the third interface and the interface control circuit. In response to detecting that a power supply device is plugged into the third interface, the power supply device control circuit detects a supply output power of the power supply device and determines a power supply control command based on the supply output power, a required charging power for the host device, and an operating power of the slave device. The interface control circuit performs on-off control on the switch circuit according to the power supply control command, to control power supply from the power supply device to the host device and the slave device. Using the connector, efficient power supply from the external power supply device to the host device and the slave device can be implemented.

摘要： Embodiments of the present disclosure may relate to apparatus, process, or techniques in a I3C protocol environment that include identifying a pending read notification message by a slave device to be sent to a master device to indicate that the data is available to be read by the master device from a buffer associated with the slave device. The pending read notification may be subsequently transmitted to the master device. Subsequently, until the data in the buffer has been read by the master device, the slave device may wait an identified amount of time that is less than a value of a timeout of the master device, and retransmit the pending read notification message to the master device. Other embodiments may be described and/or claimed.

摘要： A device includes a master device, a set of slave devices and a bus. The master device is configured to transmit first messages carrying a set of operation data message portions indicative of operations for implementation by slave devices of the set of slave devices, and second messages addressed to slave devices in the set of slave devices. The second messages convey identifiers identifying respective ones of the slave devices to which the second messages are addressed requesting respective reactions towards the master device within respective expected reaction intervals. The slave devices are configured to receive the first messages transmitted from the master device, read respective operation data message portions in the set of operation data message portions, implement respective operations as a function of the respective operation data message portions read, and receive the second messages transmitted from the master device.

In one example, a data processing device incudes a Physical Unclonable Function (PUF) source that is configured to generate PUF values, a bus, a plurality of bus access components that are configured to access the bus, and a masking information generation circuit. The masking information generation circuit is configured to generate masking information for at least one pair of bus access components using at least one PUF value and to transmit said information to the bus access components. The pair is configured in such a way that one bus access component masks the data according to the masking information generated for the pair before the data is sent over the bus and the other bus access component de-masks the data received over the bus according to the masking information generated for the pair.

摘要： A bridging module, a data transmission system, and a data transmission method are provided. The bridging module obtains a first read request, and allocates a first data storage space for first return data corresponding to the first read request. The bridging module combines a first master transaction identifier and an address of the first data storage space as a first slave transaction identifier of the first read request, and sends the first read request to a slave device. The bridging module obtains a second read request, and allocates a second data storage space for second return data corresponding to the second read request. The bridging module combines a second master transaction identifier and an address of the second data storage space as a second slave transaction identifier of the second read request, and sends the second read request to the slave device.
