  • Apparatus and method for acquiring and detecting stale data
    Patent number: 5384713
    Abstract: Stale data is detected in a shift register containing time characters representing event occurrence times, expressed in timing data counts of a cyclic counter, by comparing the most significant bit of each stored time character with a value based on the most significant bits of a current timing data count. A stale stored time character is disposed of by setting its associated validity flag, which indicates that the time character is not to be read out of the shift register.
