  • Method for compensating timing errors of real-time clocks
    Patent number: 9304498
    Abstract: The present invention relates to a method for compensating timing errors of real-time clocks, which comprises a compensating step, wherein in step 1, assign CNT to be 0 and execute step two; in step 2, assign FLAG to be 1 when a rising edge of 1 Hz clock is arrived and execute step 3; in step 3, judge FLAG and M3, if FLAG=1 and M3<0, execute step 4 while waiting until CNT=S4; if FLAG=1, CNT=0 and M3>0, execute step 5; otherwise execute step 2; in step 4, execute an assignment operation, CNT=0, M3=M3+S4, FLAG=0 and restart step 2; in step 5, execute an assignment operation, CNT=S4, M3=M3?S4, FLAG=0, and restart step 2. A sampling frequency of relative errors ERR of the present invention is adjustable, and a compensatory accuracy is much higher.
