I'm working on xCore 200 (XU232) and I got some issues regarding to the inter-tile communication. I understood that there is only 4 links between the two dies of the xCore 200, so I can use only 4 channels between the two dies. However, what's about inter-tile communication in the same die (between tile 0 and tile 1 for example) ? Is there a limitation like the inter-node one ?
The only information I found was the drawing of XU232 where it seems to have only 4 links to the switch inter-tile in the same die (in red) :

If someone has some clue about those limitations, it would be truly appreciated.
Thanks,
Marc
