arithmetic chain runs vertically allowing fast horizontal connections to
TriMatrix memory and DSP blocks. A shared arithmetic chain can
continue as far as a full column.
Similar to the carry chains, the shared arithmetic chains are also top- or
bottom-half bypassable. This capability allows the shared arithmetic
chain to cascade through half of the ALMs in a LAB while leaving the
other half available for narrower fan-in functionality. Every other LAB
column is top-half bypassable, while the other LAB columns are bottom-
half bypassable.

information on shared arithmetic chain interconnect.
Register Chain
In addition to the general routing outputs, the ALMs in an LAB have
register chain outputs. The register chain routing allows registers in the
same LAB to be cascaded together. The register chain interconnect allows
an 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 (see
advantage of these resources to improve utilization and performance.
