Abstract

See full text

In one embodiment, a method includes receiving input data bits over data channels; receiving deskew channel bits constituting frames that each comprise ones of the input data bits; determining frame boundaries; mapping each of the input data bits in each of the frames to one of the data channels; for each set of the frames, comparing the input data bits in the set with the input data bits in the corresponding input data words; determining relative delays among the data channels and the deskew channel; when non-zero delays are determined, rearranging the input data bits to reduce the delays; and when it is determined that one or more of the data channels have a delay of greater than a predetermined number of data-channel clock periods relative to a particular data channel, delaying input data bits in the particular data channel by an additional number of input data bits.
