Abstract: A method of acquiring data, a computer program product for implementing the method, a system for acquiring data, and a vehicle including the system. The method includes determining one or more data types and virtual channels required for one or more applications. The method also includes allocating a plurality of circular buffers in memory according to the determined data type(s) and virtual channel(s). One or more of the circular buffers are allocated to safety data lines. The remaining circular buffers are allocated to functional data lines. The method further includes storing at least one functional data line in a circular buffer allocated to functional data lines according to a data type and virtual channel of the functional data line. The method also includes storing at least one safety data line in a circular buffer allocated to safety data lines.

Abstract: A MIPI CSI-2/D-PHY receiving device is configured to handle being hot plugged to MIPI CSI-2/D-PHY transmitting device. During a hot plugging event, the MIPI CSI-2/D-PHY receiving device has not been initialized by receipt from the MIPI CSI-2/D-PHY transmitting device of a Stop State signal of duration TINIT. Though the MIPI CSI-2/D-PHY transmitting device is already transmitting data associated with a partial frame, the MIPI CSI-2/D-PHY receiving device will not enter into an error or unknown state, and will ignore line start/end and frame end events and drop the data packets associated with the partial frame until a frame start event corresponding to a full frame is received from the MIPI CSI-2/D-PHY transmitting device.

Abstract: A radar and/or camera system may include a receiver subsystem that receives image and/or radar data from one or more imaging/radar subsystems via multiple data lanes. A vision processor of the system may receive a data stream that includes the image and/or radar data and one or more synchronization signals including a vertical sync signal. The receiver subsystem may include a timing event generator that toggles the vertical sync signal in response to detecting certain timing event errors in order to correct these timing event errors without interrupting normal operation of the system. The receiver subsystem may include sync monitoring circuitry that may detect synchronization errors that occur when synchronization signal pulses received by the receiver subsystem do not match a predefined synchronization pattern within a scan window of predefined length. The system may be reset in response to detection of such synchronization errors.

Abstract: A video device is described that includes: a host processor comprising at least one input video port configured to receive a plurality of video data signals that comprise video data and embedded data from a plurality of virtual channels in a received frame; and a memory operably coupled to the host processor and configured to receive and store video data. The host processor is configured to segregate the video data from the embedded data in the received frame and process the embedded data individually.
