Abstract
Two pointers are initialized. The first pointer is incremented every M cycles of a monitored clock and the second pointer is incremented every N cycles of a reference clock, where M and N are determined from a frequency relationship between the clocks. If the positions of the pointers are determined to differ by more than a drift threshold, an error is detected and corrective action may be taken.
