1.1.2. Local and Direct Link Interconnects

Each LAB can drive out 40 ALM outputs. Two groups of 20 ALM outputs can drive the adjacent LABs directly through direct-link interconnects.

The direct link connection feature minimizes the use of row and column interconnects, providing higher performance and flexibility.

The local interconnect drives ALMs in the same LAB using column and row interconnects, and ALM outputs in the same LAB.

Neighboring LABs, MLABs, M20K blocks, or digital signal processing (DSP) blocks from the left or right can also drive the LAB’s local interconnect using the direct link connection.
