8.6 Output Singleton
The Decision Processor uses a particular kind of
membership function called Singleton for its output
variables. A Singleton doesn’t have a shape, like a
traditional Mbf, and is characterized by a single
point identified by the couple (X, w), where w is
calculated by the Inference Unit as described
earlier. Often, a Singleton is simply identified with
its Crisp Value X.

8.7 Fuzzy Rules
Rules can have the following structures:
if A op B op C...........then Z
if (A op B) op (C op D op E...) ...........then Z
where op is one of the possible linguistic operators
(AND/OR)
In the first case the rule operators are managed
sequentially; in the second one, the priority of the
operator is fixed by the brackets.
Each rule is codified by using an instruction set, the
inference time for a rule with 4 antecedents and 1
consequent is about 3 microseconds at 20 MHz.
The Assembler Instruction Set used to manage the
Fuzzy operations is reported in the table below.
