LAB Interconnects
The LAB local interconnect can drive all eight 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 digital signal processing (DSP) blocks from the left and right
can also drive a 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.
