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.

Systems and methods for time stamping sensor data

A method and system for providing a self-test configuration in a device is disclosed. The method and system comprise providing a self-test mechanism in a kernel space of a memory and enabling a hook in a user space of the memory, wherein the hook is in communication with the self-test mechanism. The method and system also include running the self-test driver and utilizing the results.
