Abstract
Enhanced resolution for a real-time clock is implemented, which includes a real-time clock configured to operate at a first time resolution, at least one processing unit configured to operate at a second time resolution, wherein the second time resolution has a higher frequency than the first time resolution, a memory for storing data at a location including data from the real-time clock and the at least one processing unit, an interrupt configured to load information into the memory at the location using the at least one processing unit, the interrupt further configured to operate at a frequency associated with the second time resolution, a timing service configured to read information from the memory at the location, the timing service configured to operate at the second time resolution, and a calibration module configured to re-calibrate the real-time clock.
