Functionsindedicatedmemoriesinordertoreduce
the computationaltime. Thereforea great amount
ofW.A.R.P.processing is based on alook-uptable
approachrather than on on-line calculation.
Those Membership Functions (MFs), each one
portrayed by a configurable resolution of 2
6
or 2
7
elements,arestored in fourinternalRAMs (1Kbyte
each). The consequent MFs, due to the different
modelling, are loaded in a single RAM by storing
for each MF its areaand its barycentre.Thisis due
to theadoptionof the CenterofGravity defuzzifica-
tion method.
The downloading phase allows the setting of the
device, in terms of I/O number, universes of dis-
courseandMFshapes.DuringthisphaseW.A.R.P.
prepares its internal memories for the on-line
elaboration phase and loads the microcode in its
programmemory.Thismicrocode,whichdrivesthe
on-line phase, is generated by the Compiler (see
W.A.R.P.-SDT User Manual) according to the
adoptedconfiguration.Thepossibleconfigurations
areshown in table1.
During the on-line phase (up to 40MHz working
frequency),W.A.R.P.processes theinput dataand
produces its outputsaccording to theconfiguration
loadedin the downloadingphase.
W.A.R.P. is conceivedto work together with tradi-
