Abstract: A method is described that involves loading X bits at a time into a shift register and shifting groups of older, loaded X bits up in the shift register with each new group of loaded X bits. Each group of X bits has been received from a serial data stream. The method further involves identifying an alignment key within the shift register and presenting aligned data from the serial data stream by rotating selection of a first group of Y contiguous bits from the shift register and a second group of Y contiguous bits from the shift register after the identifying. Y is greater than X.
