With the LAB-wide addnsub control signal, a single LE can implement a
one-bit adder and subtractor. This saves LE resources and improves
performance for logic functions such as DSP correlators and signed
multipliers that alternate between addition and subtraction depending
on data.
The LAB row clocks [5..0] and LAB local interconnect generate the
LAB-wide control signals. The MultiTrack
skew allows clock and control signal distribution in addition to data.
Figure 2–4
The smallest unit of logic in the Cyclone architecture, the LE, is compact
and provides advanced features with efficient logic utilization. Each LE
contains a four-input LUT, which is a function generator that can
implement any function of four variables. In addition, each LE contains a
programmable register and carry chain with carry select capability. A
single LE also supports dynamic single bit addition or subtraction mode
selectable by a LAB-wide control signal. Each LE drives all types of
interconnects: local, row, column, LUT chain, register chain, and direct
link interconnects. See
