Table 2-2. Slice Signal Descriptions
Modes of Operation
Each slice has up to four potential modes of operation: Logic, Ripple, RAM and ROM.
Logic Mode
In this mode, the LUTs in each slice are configured as 4-input combinatorial lookup tables. A LUT4 can have 16
possible input combinations. Any four input logic functions can be generated by programming this lookup table.
Since there are two LUT4s per slice, a LUT5 can be constructed within one slice. Larger look-up tables such as
LUT6, LUT7 and LUT8 can be constructed by concatenating other slices. Note LUT8 requires more than four
slices.
Ripple Mode
Ripple mode supports the efficient implementation of small arithmetic functions. In Ripple mode, the following func-
tions can be implemented by each slice:
• Addition 2-bit
• Subtraction 2-bit
• Add/subtract 2-bit using dynamic control
• Up counter 2-bit
• Down counter 2-bit
• Up/down counter with asynchronous clear
• Up/down counter with preload (sync)
• Ripple mode multiplier building block
• Multiplier support
• Comparator functions of A and B inputs
– A greater-than-or-equal-to B
– A not-equal-to B
– A less-than-or-equal-to B
