Abstract
Systems and methods are disclosed for providing sensor data to a host processor. A sequence of data samples may be generated at a sample rate established by a clock source associated with the sensor. A time stamp derived from another clock source, such as the clock employed by the host processor, is assigned to at least one of each periodically retrieved data samples. As such, at least one of the assigned time stamps then may be adjusted by applying a correction determined from a timing characteristic associated with retrieval of the data samples.
