FLEX 10KE Embedded Programmable Logic Family Data Sheet
Normal Mode
The normal mode is suitable for general logic applications and wide
decoding functions that can take advantage of a cascade chain. In normal
mode, four data inputs from the LAB local interconnect and the carry-in
are inputs to a 4-input LUT. The MAX+PLUS II Compiler automatically
selects the carry-in or the DATA3 signal as one of the inputs to the LUT. The
LUT output can be combined with the cascade-in signal to form a cascade
chain through the cascade-out signal. Either the register or the LUT can be
used to drive both the local interconnect and the FastTrack Interconnect
routing structure at the same time.
The LUT and the register in the LE can be used independently (register
packing). To support register packing, the LE has two outputs; one drives
the local interconnect, and the other drives the FastTrack Interconnect
routing structure. The DATA4 signal can drive the register directly,
allowing the LUT to compute a function that is independent of the
registered signal; a 3-input function can be computed in the LUT, and a
fourth independent signal can be registered. Alternatively, a 4-input
function can be generated, and one of the inputs to this function can be
used to drive the register. The register in a packed LE can still use the
clock enable, clear, and preset signals in the LE. In a packed LE, the
register can drive the FastTrack Interconnect routing structure while the
LUT drives the local interconnect, or vice versa.
Arithmetic Mode
The arithmetic mode offers two 3-input LUTs that are ideal for
implementing adders, accumulators, and comparators. One LUT
computes a 3-input function; the other generates a carry output. As shown
inputs from the LAB local interconnect to generate a combinatorial or
registered output. For example, in an adder, this output is the sum of three
signals: a, b, and carry-in. The second LUT uses the same three signals to
generate a carry-out signal, thereby creating a carry chain. The arithmetic
mode also supports simultaneous use of the cascade chain.
Up/Down Counter Mode
The up/down counter mode offers counter enable, clock enable,
synchronous up/down control, and data loading options. These control
signals are generated by the data inputs from the LAB local interconnect,
the carry-in signal, and output feedback from the programmable register.
Two 3-input LUTs are used: one generates the counter data, and the other
generates the fast carry bit. A 2-to-1 multiplexer provides synchronous
loading. Data can also be loaded asynchronously with the clear and preset
register control signals without using the LUT resources.
