1. A system for event timing measurement, comprising:

  • serializer circuitry having a digital signal pattern as an input and having a bit stream as an output, the digital signal pattern being multi-bit parallel data and the bit stream being single-bit serial data;

    logic circuitry having the bit stream as an input and having an event occurrence signal as an input, the logic circuitry being configured to modify the bit stream based upon the event occurrence signal to produce a modified bit stream, the modified bit stream being single-bit serial data;

    deserializer circuitry having the modified bit stream as an input and having a modified digital signal pattern as an output, the modified digital signal pattern being multi-bit parallel data; and

    event timing detector circuitry configured to compare a predicted digital signal pattern to the modified digital signal pattern to determine when an event occurred within the modified digital signal pattern and to output event timing data representative of when the event occurred within the modified digital signal pattern, the event timing data having a resolution related to a bit period for the modified bit stream.
