2.4 FUZZY CORE
ST52x301Fuzzy Core main featuresare:
Up to 4 Inputswith 8-bit resolution
Up to 16 Membership Functions(Mbfs)for each
Input (64 possibleMbfs)
Up to 2 Outputswith 8-bitresolution
Possibility to process fuzzy rules with a max.
number of 8 antecedents
2.4.1 Internal Structure
The block diagram shown in figure 2.9 describes
thestructureofST52x301FuzzyCore.Inthisfigure
wecandistinguishdifferentfunctionalblocks:Alpha
Calculator, Inference Unit and Defuzzifier.These
blocks allow to perform a MAMDANI type fuzzy
inferencewith crisp consequents.It is importantto
underline that the fuzzy inference is performedby
usingasinputsthe first4 locationsof theRegisters

Figure2.9.Fuzzy Core Block Diagram
Notice that the inputs for this block come from the
firstfourlocationsof theRegisterFile;itmeans the
user, to evaluate a fuzzy function, must load the
input values in these registers.
Alpha Calculator performs what is called
fuzzification
: the input data are transformed in
activationlevel (alpha weight) of the Mbfs.
