module simply takes the output of the descriptor buffer and reformats the data

* descriptor format then add it to this block. This block also provides the descriptor information
* using a naming convention isn't of bit indexes in a 256 bit wide command signal.

/* These barrelshifters will take the unaligned data coming into this block and shift the byte lanes appropriately to form a single packed word.
Zeros are shifted into the byte lanes that do not contain valid data for the combined word that will be buffered. This allows both barrelshifters
to be logically OR'ed together to form a single packed word. Shifter A is used to shift the current read data towards the upper bytes of the
combined word (since those are the upper addresses of the combined word). Shifter B after the pipeline stage called 'barrelshifter_B_d1' contains
the previously read data shifted towards the lower bytes (since those are the lower addresses of the combined word).
