ABSTRACT:
A network device includes an alignment module to align payloads of received frames on memory boundaries in a buffer memory. The frames may be Ethernet frames which encapsulate IP (Internet Protocol) packets as payloads. The alignment module modifies the frame to shift the IP payload into a position in the memory regions such that the IP payload is aligned with the memory boundaries. The number x of non-data bits can be determined according to x=m*c+p, where m is the bit depth of memory regions, n is the length of a header, p is the non-zero remainder of the ratio n/m, and c is an integer.
