LAB Interconnects
The LAB local interconnect can drive ALMs in the same LAB. It is driven
by column and row interconnects and ALM outputs in the same LAB.
Neighboring LABs, M512 RAM blocks, M4K RAM blocks, M-RAM
blocks, or DSP blocks from the left and right can also drive an LAB's local
interconnect through the direct link connection. The direct link
connection feature minimizes the use of row and column interconnects,
providing higher performance and flexibility. Each ALM can drive
24 ALMs through fast local and direct link interconnects.
