The ALM is the basic building block of logic in the Arria II device architecture. Each
ALM contains a variety of LUT-based resources that can be divided between two
combinational adaptive LUTs (ALUTs) and two registers. With up to eight inputs for
the two combinational ALUTs, one ALM can implement various combinations of two
functions. This adaptability allows an ALM to be completely backward-compatible
with 4-input LUT architectures. One ALM can also implement any function with up
to 6-input and certain 7-input functions. In addition to the ALUT-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, an 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.
