Abstract:
Systems, methods, and apparatuses are described for deskewing between multiple lane groups of deskewed data streams. Multiple distinct and deskewed lane groups can be aligned by utilizing an inter-group synchronized set of counters. The counters supply a way to measure the time delta (counter difference) in clocks between the multiple streams. Using this delta, one or more streams can be stalled to align the multiple streams. The counter values are communicated between the multiple groups in a way that they align to set data stream markers. These fixed markers and the breaking up of the counters in relation to the periodicity of the markers allows for a robust way to compare the multiple streams and calculate an accurate time delta.
