Abstract
Methods and systems for network devices are provided. One method includes receiving a serial data stream at a network interface of a network device coupled to a network link to communicate with other networked devices, the data stream including an alignment marker with a bit pattern for recovering a bit stream used by network device logic for processing the received serial data stream; using a plurality of comparators for simultaneously comparing within a single clock cycle, portions of a parallel data stream generated after converting the serial data stream by a de-serializer of the network device; detecting the bit pattern of the alignment marker in the parallel data stream by one of the plurality of comparators; storing a starting bit position of the alignment marker in the parallel data stream; and reordering the parallel data stream based on the stored starting bit position of the alignment marker.
