I just checked the VIP manual to see if it mentions anything about bursting boundaries. I didn't find anything too specific, but it does state the following: --- Quote Start --- To prevent memory read and write bursts from being spread across two adjacent memory rows, you can turn on an option to align the initial address of each read and write burst to a multiple of the burst target used for the read and write masters (or the maximum of the read and write burst targets if using different values). Turning on this option may have a negative impact on memory usage but increases memory efficiency. --- Quote End ---
