Register Chain
1
In addition to general routing outputs, the ALMs in any given LAB have register
chain outputs to allow registers in the same LAB to be cascaded together. The register
chain interconnect allows a LAB to use LUTs for a single combinational function and
the registers to be used for an unrelated shift register implementation. These resources
speed up connections between ALMs while saving local interconnect resources (refer
to
resources to improve utilization and performance.

Note to
(1) You can use the combinational or adder logic to implement an unrelated, un-registered function.
