FLEX 10KE Embedded Programmable Logic Devices Data Sheet
Figure 9 shows how an n-bit full adder can be implemented in n +1 LEs
with the carry chain. One portion of the LUT generates the sum of two bits
using the input signals and the carry-in signal; the sum is routed to the
output of the LE. The register can be bypassed for simple adders or used
for an accumulator function. Another portion of the LUT and the carry
chain logic generates the carry-out signal, which is routed directly to the
carry-in signal of the next-higher-order bit. The final carry-out signal is
routed to an LE, where it can be used as a general-purpose signal.
