W.A.R.P.1.1
Functionsin dedicatedmemories in order to reduce
the computational time. Therefore a great amount
of W.A.R.P. processing is based on a look-up table
approach rather than on on-line calculation.
Those Membership Functions (MFs), each one
portrayed by a configurable resolution of 2⁶ or 2⁷
elements, are stored in four internal RAMs (1Kbyte
each). The consequent MFs, due to the different
modelling, are loaded in a single RAM by storing
for each MF its area and its barycentre. This is due
to the adoptionof the Center of Gravity defuzzifica-
tion method.
The downloading phase allows the setting of the
device, in terms of I/O number, universes of dis-
course and MF shapes. During this phase W.A.R.P.
prepares its internal memories for the on-line
elaboration phase and loads the microcode in its
program memory. This microcode, which drives the
on-line phase, is generated by the Compiler (see
W.A.R.P.-SDT User Manual) according to the
adopted configuration. The possible configurations
are shown in table 1.
During the on-line phase (up to 40MHz working
frequency), W.A.R.P. processes the input data and
produces its outputs according to the configuration
loaded in the downloading phase.
W.A.R.P. is conceived to work together with tradi-
tional microcontrollers which shall perform normal
control tasks while W.A.R.P. will be indipendently
responsible for all the fuzzy related computing.
W.A.R.P. is manufactured using the high perform-
ance, reliable HCMOS4T (O.7µm) SGS-THOMSON
Microelectronics process.
