Abstract: In one example, a system for transmitting encrypted data includes a processor to select a virtual channel to be encrypted between an application processor and an image sensor during an initialization process. The processor can also transmit a virtual channel command corresponding to the selected virtual channel to the image sensor. The processor can also poll a register in the image sensor to verify the image sensor has stored an encryption key corresponding to the selected virtual channel and detect image data from the image sensor via the virtual channel, the image data encrypted with the encryption key.

Abstract: In one example, a system for modifying transmission of image data includes a processor to detect a camera management command to transmit to an image sensor via a camera serial interface link. The processor can also transmit the camera management command to the image sensor via the camera serial interface link, and receive image data from the image sensor via the camera serial interface link.

Abstract: Techniques and mechanisms for communicating packets of image information, the packets each having a respective format that is defined or otherwise indicated by a camera serial interface standard. In an embodiment, circuitry of a first physical layer (PHY) is operated to facilitate such communication via a lane of an interconnect that is coupled between the first PHY and a second PHY. The PHYs further communicate between each other a packet delimiter sequence between two such packets. In another embodiment, the plurality of packets and the packet delimiter sequence are communicated after a transition of one PHY from a relatively low power state, and prior to any subsequent transition of that PHY back to the relatively low power state. The camera serial interface standard specifies or otherwise indicates a protocol whereby a transition to such a low power state is performed between the respective communications of any two successive packets.

Abstract: In one embodiment, a system includes a host system-on-chip (SoC) comprising vision processing circuitry and a camera connected to the host SoC through an Inter-Integrated Circuit (I3C) bus. The camera includes circuitry to generate image data and transmit an interrupt signal to the host SoC over the I3C bus indicating the image data is ready for transfer. The host SoC vision processing circuitry is to transmit a read message to the camera over the I3C bus based on the interrupt signal and receive a set of line payload packets including the image data over the I3C bus based on the read message.

Abstract: Techniques and mechanisms to exchange sensor information between devices. In one embodiment, sensor data and corresponding metadata are stored, respectively, to a first buffer and a second buffer of a first device that is coupled to a host device via a hardware interface of the first device and serial bus. The sensor data and metadata are communicated to the host using a protocol that is compatible with a bidirectional, serial command interface standard. Communication of sensor information between the devices is according to a priority of the second buffer over the first buffer. In another embodiment, the metadata includes a token indicating to the host device a risk of sensor data being overwritten at the first buffer or a risk of the first buffer being starved of sensor data.
