Abstract
Apparatus is described for realigning a sequence of data bytes, such as a received datagram. The data is initially written into a multi-lane FIFO buffer, with the data in each lane pre-skewed by a controllable amount, determined by the address of the buffer area into which the data is to be transferred. The data is then read out of the FIFO buffer through a lane changer which rotates the order of the lanes by a controllable amount, also determined by the address of the buffer area. The apparatus can be used, for example, to realign data to ensure that the data is correctly aligned with cache line boundaries.
