LE Operating Modes
The ACEX 1K LE can operate in the following four modes:
I
Normal mode
I
Arithmetic mode
I
Up/down counter mode
I
Clearable counter mode
Each of these modes uses LE resources differently. In each mode, seven
available inputs to the LE—the four data inputs from the LAB local
interconnect, the feedback from the programmable register, and the
carry-in and cascade-in from the previous LE—are directed to different
destinations to implement the desired logic function. Three inputs to the
LE provide clock, clear, and preset control for the register. The Altera
software, in conjunction with parameterized functions such as LPM and
DesignWare functions, automatically chooses the appropriate mode for
common functions such as counters, adders, and multipliers. If required,
the designer can also create special-purpose functions that use a specific
LE operating mode for optimal performance.
The architecture provides a synchronous clock enable to the register in all
four modes. The Altera software can set DATA1 to enable the register
synchronously, providing easy implementation of fully synchronous
designs.
Figure 11 shows the ACEX 1K LE operating modes.
