GENERAL DESCRIPTION
W.A.R.P. is a VLSI Fuzzy Logic controller whose
architecture arises from the need of realizing an
integrated structure with high inferencing perform-
ances and flexibility. To get those results a modular
architecture based on a set of parallel memory
blocks has been implemented.
In order to obtainhigh performances W.A.R.P. uses
different data representations during the various
phases of the computational cycle, so that it is
always operating on the optimal data repre-
sentation. A vectorial characterization has been
adopted for the Antecedent Membership Func-
tions. W.A.R.P. exploits a SGS-THOMSON pat-
ented strategy to store the AntecedentMembership
