Register Chain
Arria II GX Device Handbook, Volume 1
1
In addition to general routing outputs, the ALMs in any given LAB have register
chain outputs. This allows 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
advantage of these resources to improve utilization and performance.

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