1.1.2. Local and Direct Link Interconnects

Each LAB can drive 30 ALMs through fast-local and direct-link interconnects. Ten ALMs are in any given LAB and ten ALMs are in each of the adjacent LABs.

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

Neighboring LABs, MLABs, M10K 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.

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