The four LUTs share the dataa and datab inputs. As shown in
carry-in signal feeds to adder0, and the carry-out from adder0 feeds to carry-in of
adder1. The carry-out from adder1 drives to adder0 of the next ALM in the LAB.
ALMs in arithmetic mode can drive out registered and/or unregistered versions of
the adder outputs.
While operating in arithmetic mode, the ALM can support simultaneous use of the
adder's carry output along with combinational logic outputs. In this operation, the
adder output is ignored. This usage of the adder with the combinational logic output
provides resource savings of up to 50% for functions that can use this ability. An
example of such functionality is a conditional operation, such as the one shown in
Figure
2–12.
