A network hub is provided for an onboard network system. The onboard network system includes first and second networks for transmission of first-type and second-type frames following first and second communication protocols. The network hub includes a receiver that receives a first-type frame. A processor determines whether or not the first-type frame received by the receiver includes first information that is a base for a second-type frame to be transmitted to the second network, to obtain a determination result, and selects a port to send a frame based on the first-type frame based on the determination result. A transmitter sends the frame based on the first-type frame to a wired transmission path connected to the port selected by the processor based on the first-type frame received by the receiver.

In some examples, a transport agnostic source includes a streaming device to stream video on diverse transport topologies including isochronous and non-isochronous transports. In some examples, a transport agnostic sink includes a receiving device to receive streamed video from diverse transport topologies including isochronous and non-isochronous transports.

A network node for coupling to a communication bus, the node comprising: a receiver configured to receive messages from the communication bus; and a transmitter configured to transmit first messages having a first message format and configured to transmit diagnosis messages having a second message format on the communication bus for use in determination of communication errors, wherein said transmitter is configured to send said one or more diagnosis messages having one or more of: (i) a predetermined pattern of symbols; (ii) a predetermined sending schedule; (iii) a predetermined line encoding method; (iv) a predetermined bit rate; (v) a predetermined position in one or more of the first messages; (vi) a predetermined signalling frequency that is out of a frequency band used for transmission of the first messages; and (vii) a predetermined signal strength different from the signal strength used to send the first messages.

A method includes receiving first data at a controller of an ADAS via a first virtual channel of a camera serial interface 2 (CSI-2) data interface. The method also includes receiving second data at the controller of the ADAS via a second virtual channel of the CSI-2 data interface. The method includes storing the first data at a first address in a memory, the first address specified by the first virtual channel. The method also includes storing the second data at a second address of a control register, the control register specified by the second data. The method includes performing a test using the first data and the second data.

An array controlling system includes a database, a controlling center and an array device. The controlling center reads a plurality of data of the database. The array device includes a processing unit, a main bus and an array unit. The processing unit receives a command of the controlling center and converts the command into a communication data. The main bus is configured to transmit the communication data to the array unit. A plurality of array modules of the array unit are connected in series with each other through a serial bus, and sequentially receive the communication data. The processing unit controls each of the array modules according to the communication data. A plurality of sensing data of the array modules are collected to the processing unit. The processing unit returns the sensing data to the database or the controlling center to update the database.

To realize a low power consumption and a small area of a network communication system and a semiconductor device for mounting the same. In the processing method of the network router or network communication frame, the received frame is input to the hash generator, to obtain an address based on the resulting hash value, the position of the address in the rule table, stores the rule corresponding to the received frame.
