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 a LAB.
The speed advantage of the carry-select chain is in the parallel
pre-computation of carry chains. Since the LAB carry-in selects the
precomputed carry chain, not every LE is in the critical path. Only the
propagation delays between LAB carry-in generation (LE 5 and LE 10) are
now part of the critical path. This feature allows the Cyclone architecture
to implement high-speed counters, adders, multipliers, parity functions,
and comparators of arbitrary width.
