2–7:
Normal Mode
Normal mode is suitable for general logic applications and combinational functions.
In this mode, up to eight data inputs from the LAB local interconnect are inputs to the
combinational logic. Normal mode allows two functions to be implemented in one
Stratix IV ALM, or a single function of up to six inputs. The ALM can support certain
combinations of completely independent functions and various combinations of
functions that have common inputs.
Figure 2–7
Normal mode provides complete backward-compatibility with four-input LUT
architectures.
