  • Publication number: 20230205723
    Abstract: The present disclosure relates to a communication device, a communication method, and a program for offering adaptability to a wider variety of applications and enhancing reliability of communications. With a CCI protocol implemented as an upper layer, a physical layer transmits and receives data including an extended header and an extended footer to and from another communication device. A CCI-FS processing section compares a Desination ID included in the extended header with an ID (Source ID) given to the communication device, and determines whether or not the data is for accessing the communication device. The physical layer is MIPI A-PHY that has an asymmetrical upper layer of a point-to-point topology and is designed to allow high-speed data transmission, control data, and electric power to share one physical wire. The present technology is applicable to a communication system that is used for connection in an in-vehicle camera, for example.

  • Patent number: 10129371
    Abstract: A serial communication device includes a serializer configured to transmit serial data for each channel via a transmission line for the corresponding channel, and a deserializer configured to receive the serial data. The serializer includes a transmission processing circuit that creates a protocol where pieces of valid data are inserted between a start frame and an end frame for each channel. The deserializer includes buffers for the respective channels to detect the start frame of each channel, store the valid data in the corresponding buffer, set, as a to-be-processed buffer, at least one buffer that stores the valid data on a channel to be deskewed, start externally transferring data from the to-be-processed buffer when a fixed amount of the valid data is stored or when the end frame is detected, detect a boundary between the valid data and the end frame, and extract the valid data from the to-be-processed buffer.

  • Patent number: 10044535
    Abstract: A serial communication apparatus includes an adder configured to add a start code and a length code to a head of data, a transmitter configured to convert the data together with the added start code and the added length code into a serial format and to transmit the converted data including the start code and the length code, a receiver configured to receive the converted data transmitted from the transmitter, and a processor configured to detect the start code and the length code included in the received converted data, to specify the head of the data based on the detected start code, to specify a tail of the data based on the detected start code and the detected length code, and to process the converted data based on the specified head and the specified tail of the data.

  • Patent number: 9035695
    Abstract: A semiconductor integrated circuit and an integrated circuit, each of which includes multiple regions containing at least one switchable region to switch between supplying power and blocking power individually; a power supply controller to control switching supplying power and blocking power in the switchable region that switches supplying power and blocking power individually; a power supply variable impedance circuit to change a power supply impedance of the semiconductor integrated circuit; and a power supply impedance controller to obtain the power supplying state of the region from the power supply controller, to cause the power supply variable impedance circuit to change the power supply impedance, based on a supply state of the power in the switchable region.
