SYNC: W.A.R.P. uses this pin to synchronize input
data from an external database in off-line mode.
The database contains information about antece-
dent and consequent membership functions and
about fuzzy rules. To memorize this database it is
possible to use an host processor or a non volatile
memory.
FUNCTIONAL DESCRIPTION
W.A.R.P. works in two mode depending on the OFL
control signal level:
Off-line MODE (OFL High)
On-line MODE (OFL Low)
OFF-LINE MODE
All W.A.R.P. memories are loaded during the off-
line phase. The membership functions are written
inside their related memories and the process con-
trol rules are loaded inside the program memory.
If the CHM switch has been set low then the
addresses of the words to be written in the memo-
ries are provided by an external bus (A0-A9), while
data must be loaded 8 bit a time in the data bus.
If the CHM switch has been set high then the
addresses of the words to be written in the memo-
ries are internally generated while the addresses
of the EPROM’s locations to be read are directly
