1.1.2. LE Operating Modes
- Normal mode
- Arithmetic mode
These operating modes use LE resources differently. Both LE modes have six available inputs and LAB-wide signals.
The Intel® Quartus® Prime software automatically chooses the appropriate mode for common functions, such as counters, adders, subtractors, and arithmetic functions, in conjunction with parameterized functions such as the library of parameterized modules (LPM) functions.
You can also create special-purpose functions that specify which LE operating mode to use for optimal performance.
