Shared Arithmetic Chain
The shared arithmetic chain available in enhanced arithmetic mode allows the ALM
to implement a three-input add. This significantly reduces the resources necessary to
implement large adder trees or correlator functions.
The shared arithmetic chains can begin in either the first or sixth ALM in an LAB. The
Quartus II Compiler creates shared arithmetic chains longer than 20 (10 ALMs in
arithmetic or shared arithmetic mode) by linking LABs together automatically. For
enhanced fitting, a long shared 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 top and bottom half of shared arithmetic chains in
alternate LAB columns can be bypassed. 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.
