Abstract
In PCI-Express and alike communications systems, number of lanes used per channel or port can vary as a result of negotiated lane aggregation during network bring-up. Disclosed are systems and methods for efficiently realigning packet data and stripping out control bytes in a by-eight port configuration as the packet data ingresses from the physical layer (PL), past the data link layer (DL) and into the transaction layer (TL). It is shown that data routing can be reduced to just two, mux-selectable permutations based on whether the STP (start of packet) character arrives in an even numbered double-word side (DW) or an odd-numbered double-word side (DW) of a physical layer register.
