R24 row interconnects span 24 LABs and provide the fastest resource for long row
connections between LABs, TriMatrix memory, DSP blocks, and row IOEs. The R24
row interconnects can cross M-RAM blocks. R24 row interconnects drive to other row
or column interconnects at every fourth LAB and do not drive directly to LAB local
interconnects. R24 row interconnects drive LAB local interconnects via R4 and C4
interconnects. R24 interconnects can drive R24, R4, C16, and C4 interconnects. The
column interconnect operates similarly to the row interconnect and vertically routes
signals to and from LABs, TriMatrix memory, DSP blocks, and IOEs. Each column of
LABs is served by a dedicated column interconnect.
These column resources include:

Arria GX devices include an enhanced interconnect structure in LABs for routing
shared arithmetic chains and carry chains for efficient arithmetic functions. The
register chain connection allows the register output of one ALM to connect directly to
the register input of the next ALM in the LAB for fast shift registers. These
ALM-to-ALM connections bypass the local interconnect. The Quartus II Compiler
automatically takes advantage of these resources to improve utilization and
performance.
