Modes of Operation
Each Slice is capable of four modes of operation: Logic, Ripple, RAM, and ROM. The Slice in the PFF is capable of
all modes except RAM. Table 2-2 lists the modes and the capability of the Slice blocks.

Logic Mode: In this mode, the LUTs in each Slice are configured as 4-input combinatorial lookup tables (LUT4). A
LUT4 can have 16 possible input combinations. Any logic function with four inputs can be generated by program-
ming this lookup table. Since there are two LUT4s per Slice, a LUT5 can be constructed within one Slice. Larger
lookup tables such as LUT6, LUT7, and LUT8 can be constructed by concatenating other Slices.
Ripple Mode: Ripple mode allows the efficient implementation of small arithmetic functions. In ripple mode, the fol-
lowing functions can be implemented by each Slice:

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
Two additional signals, Carry Generate and Carry Propagate, are generated per Slice in this mode, allowing fast
arithmetic functions to be constructed by concatenating Slices.
RAM Mode: In this mode, distributed RAM can be constructed using each LUT block as a 16x2-bit memory.
Through the combination of LUTs and Slices, a variety of different memories can be constructed.
The ispLEVER design tool supports the creation of a variety of different size memories. Where appropriate, the
software will construct these using distributed memory primitives that represent the capabilities of the PFU.
Table 2-3 shows the number of Slices required to implement different distributed RAM primitives. Figure 2-6 shows
the distributed memory primitive block diagrams. Dual port memories involve the pairing of two Slices. One Slice
functions as the read-write port, while the other companion Slice supports the read-only port. For more information
on RAM mode in MachXO devices, please see details of additional technical documentation at the end of this data
sheet.
