completely backward-compatible with four-input LUT architectures. One
ALM can also implement any function of up to six inputs and certain
seven-input functions.
In addition to the adaptive LUT-based resources, each ALM contains two
programmable registers, two dedicated full adders, a carry chain, a
shared arithmetic chain, and a register chain. Through these dedicated
resources, the ALM can efficiently implement various arithmetic
functions and shift registers. Each ALM drives all types of interconnects:
local, row, column, carry chain, shared arithmetic chain, register chain,
and direct link interconnects.
