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.
