摘要
A method includes reading first and second timer count values from a timer. The first timer count value is associated with a first time point, and the second timer count value is associated with a second time point. Also, the method includes calculating a difference between the first and the second timer count values, and determining whether the difference is within a range. The range is based on a desired executing frequency to perform a computing task, a variation of the desired executing frequency, and a timer frequency. Further, based on the difference not being within the range, the method includes setting an error flag value to be true and incrementing an error count value.
