The smallest unit of logic in the MAX II 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 an LAB-wide control signal. Each LE drives all types of interconnects:
local, row, column, LUT chain, register chain, and DirectLink interconnects. See
