Combinational
Logic
The basic building block of logic in the Stratix II 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.
