The dedicated input signals
can drive the clock and
asynchronous clear signals.
Dedicated Inputs
4
Input signals to the first
LE in an LAB (i.e., LE 1)
can be rerouted to drive
control signals within
the LAB.
LE 1
LABCTRL1/
SYNCLR
LABCTRL2
CLK1/SYNLOAD
CLK2
LAB-wide control signals
(SYNCLR and SYNLOAD
signals are used in counter mode).
Logic Element
An LE, the smallest unit of logic in the FLEX 6000 architecture, has a
compact size that provides efficient logic usage. Each LE contains a four-
input LUT, which is a function generator that can quickly implement any
function of four variables. An LE contains a programmable flipflop, carry
and cascade chains. Additionally, each LE drives both the local and the
FastTrack Interconnect. See Figure 4.
