2–8:
(1)
The other two LUTs use the data1 and data2 signals to generate two possible carry-out
signals: one for a carry of 1 and the other for a carry of 0. The carry-in0 signal acts
as the carry-select for the carry-out0 output and carry-in1 acts as the carry-
select for the carry-out1 output. LEs in arithmetic mode can drive out registered
and unregistered versions of the LUT output.
The dynamic arithmetic mode also offers clock enable, counter enable, synchronous
up/down control, synchronous clear, synchronous load, and dynamic
adder/subtractor options. The LAB local interconnect data inputs generate the
counter enable and synchronous up/down control signals. The synchronous clear
and synchronous load options are LAB-wide signals that affect all registers in the
LAB. The Quartus II software automatically places any registers that are not used by
the counter into other LABs. The addnsub LAB-wide signal controls whether the LE
acts as an adder or subtractor.
Carry-Select Chain
The carry-select chain provides a very fast carry-select function between LEs in
dynamic arithmetic mode. The carry-select chain uses the redundant carry calculation
to increase the speed of carry functions. The LE is configured to calculate outputs for a
possible carry-in of 0 and carry-in of 1 in parallel. The carry-in0 and carry-in1
signals from a lower-order bit feed forward into the higher-order bit via the parallel
carry chain and feed into both the LUT and the next portion of the carry chain. Carry-
select chains can begin in any LE within an LAB.
