56 / 316 page  2–48 Altera Corporation Stratix II GX Device Handbook, Volume 1 October 2007 Adaptive Logic Modules Adaptive Logic Modules 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. Figure 2–35 shows a high-level block diagram of the Stratix II GX ALM while Figure 2–36 shows a detailed view of all the connections in the ALM. Figure 2–35.
