The basic building block of logic in the Arria GX architecture is the ALM. The ALM
provides advanced features with efficient logic utilization. Each ALM contains a
variety of look-up table (LUT)-based resources that can be divided between two
adaptive LUTs (ALUTs). With up to eight inputs to the two ALUTs, one ALM can
implement various combinations of two functions. This adaptability allows the ALM
to be 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.
