ABSTRACT:
One embodiment of an apparatus for generating a time stamp includes a clock input, an event signal input and a time stamp output. A DLL is connected to the clock input, with a plurality of delay elements inside the DLL. An output of each of the delay elements is connected to a data input on a latch. An event signal input is connected to an enable input on each of the latches. An output of each of the latches is connected to the time stamp output. The apparatus is adapted to produce a value on the time stamp output indicating a point at which the event signal input transitions between transitions on the clock input.
