    Abstract: Disclosed are methods and apparatus for transmitting sensor timing correction messages with a host controller. The methods and apparatus determine synchronization messages that are transmitted to a sensor coupled with the host controller via an interface, where the messages indicate a beginning of a synchronization period for synchronizing timing of the host controller and the sensor. Additionally, a delay time message is determined that indicates a time delay between the beginning of the synchronization period and an actual transmission time of the synchronization message. The synchronization message is transmitted with the delay time message in an information message to the sensor, where information message is configured to allow the sensor to correct timing of a sensor timer by accounting for the delay time.

    Abstract: Disclosed are methods and apparatus for synchronizing a controller and sensors in a system. A timestamp is provided in a host controller of an interface event on an interface coupled with host controller through detecting a message from a sensor on the interface that identifies the issuance of the interface event caused by the sensor at a first time. In response, the controller issues first and second events on the interface at respective second and third times, while concurrently counting cycles of a clock in the controller after each issuance. The controller also receives a first and second sensor counts representing the internal sensor clock times noted for the first and second events. The controller may then accurately calculate the timestamp of the interface event corresponding to the first time based on both internal controller counts and the sensor counts without needing a timestamp from the sensor directly.

    Abstract translation: 公开了用于同步系统中的控制器和传感器的方法和设备。 在与主控制器耦合的接口上的接口事件的主控制器中通过检测来自接口上的传感器的消息来提供时间戳,所述消息识别第一时间由传感器引起的接口事件的发布。 作为响应,控制器分别在第二次和第三次在接口上发布第一和第二事件,同时在每次发布之后对控制器中的时钟周期进行计数。 该控制器还接收第一和第二传感器计数,该第一和第二传感器计数表示针对第一和第二事件记录的内部传感器时钟时间。 然后,控制器可以基于内部控制器计数和传感器计数精确地计算与第一次对应的接口事件的时​​间戳,而不需要直接来自传感器的时间戳。
