8.5 Input Membership Function
The Decision Processor allows the management of
triangular Mbfs. In order to define an Mbf, three
different parameters must be stored on the
Program/Data Memory (see

In order to reduce the size of the memory area and
the computational effort the vertical range of the
vertex is fixed between 0 and 15 (4 bits)
By using the previous memorization method
different kinds of triangular Membership Functions

of valid Mbfs that can be defined in ST52F510/
F513.
Each Mbf is then defined storing 3 bytes in the first
Kbyte of the Program/Data Memory.
The Mbf is stored by using the following instruction:
MBF n_mbf lvd v rvd
where:
n_mbf is a tag number that identifies the Mbf
lvd, v, and rvd are the parameters that describe the
Mbf’s shape as described above.
