FUNCTIONAL DESCRIPTION
W.A.R.P.2.0 works in two mode dependingon the
OFL controlsignal level (see table 3) :
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 membershipfunctionsare written
inside their related memories andthe process con-
trol rules are loaded inside the PCM.
The addresses of the words to be written in the
memories, are internally generated while the ad-
dresses of the external memory locations to be
readaredirectlyprovidedbyW.A.R.P.2.0bymeans
of O0-O11output pins.
Data must be loaded 8 bit a time in the data bus
and can be read from an external non volatile
memory or loaded by an hostprocessor.
The Off-Line phase can be performed automat-
ically (see figure 4) or manually(see figure 5).
When the auto-boot is chosen(AUTO = High) it is
possibleto configurethe readingaccess timeofthe
externalmemory. Theauto-bootendisindicatedby
the ENDOFL signal.
The downloading phase requires:
F*NWordsDatabaseclock pulses,
where F is 16 or 32 (see table2).
NWordsDatabaseis the number of words storedin
the boot-memory (see register bench description,
table 5).
When the manual-boot is chosen (AUTO = Low)
datahavetobe providedby usingthe handshaking
signals (RD/READY). In this way it is possible to
updateonly aportionofthe databaseorchangethe
processorconfiguration.
The time required from the manual boot depends
on the efficiency of the communication handled
with the handshakingsignals.
