7 Series MIG - No support for BC4


The user interface for Virtex-6 and 7 series look similar, however the documentation for 7 series MIG does not show any support for Burst Chop 4.


Burst Chop 4 (BC4) is not supported for the 7 Series Memory Controller. 

BC4 was not commonly used in Virtex-6 because a BC4 still requires a burst of 8 with only 4 of the bursts containing valid data. 

This limits efficiency to a maximum of 50%. 

Because BC4 was not commonly used in Virtex-6, support for BC4 was removed in 7 series MIG.
