Spartan-6 GTP - comma detection when align_comma_word=2

Description


If ALIGN_COMMA_WORD=2 and parallel data width is 4 bytes, the comma can be presented on either byte2 or byte0.

How can it be fixed to byte0 or byte2?

Solution


You will need to use fabric to implement a shifter.
 
Once the received comma is not presented at the intended byte, the shifter will move the comma to the expected position.
