Example 1:

IF Input1 IS NOT Mbf1 AND Input4 is Mbf12 OR Input3 IS Mbf8 THEN Crisp1

is codified by the following instructions

LDN 1 1

calculates the NOT

α value of Input1 with Mbf1 and stores the result in the data stack

LDP 4 12

fixes the

α value of Input4 with M12 and stores the result in the data stack

FZAND

adds the NOT

α and α values obtained with the operations LDN1 1 and LDP 4 12

LDK

stores the result of the operation FZAND in the data stack

LDP 3 8

fixes the

α value of Input3 with Mbf8 and stores the result in the data stack

FZOR

implements the operation OR between the results obtained with the operations LDK

and LDP

CON crisp1

multiplies the result of the last

Ω operation with the crisp value Crisp1

Example 2, the priority of the operator is fixed by the brakets:

IF (Input3 IS Mbf1 AND Input4 IS NOT Mbf15) OR (Input1 IS Mbf6 OR Input6IS NOT Mbf14) THEN Crisp2

LDP 3 1

fixes the

α value of Input3 with Mbf1 and stores the result in the data stack

LDN 4 15

calculates the NOT

α value of Input4 with Mbf15 and stores the result in the data

stack

FZAND

adds NOT

α and α values obtained with the operations LDP 3 1 and LDN 4 15

SKM

stores the result of the operation FZAND in the memory register M

LDP 1 6

fixes the

α value of Input1 with Mbf6 and stores the result in the data stack

LDN 2 14

calculates the NOT

α value of Input6 with Mbf14 and stores the result in the data

stack

FZOR

implements the operation OR between the

α and NOT α values obtained with the

two previous operations (LDP 1 6 and LDN 2 14)

LDK

stores the result of the operation OR in the data stack

LDM

copies the value of the memory register M in the data stack

FZOR

implements the operation OR between the last two values stored in the data stack

(LDK and LDM)

CON crips2

multiplies the result of the last

Ω operation with the crisp value Crip2

At the end of the fuzzy rules set a byte, to identify

the output involved in the rules, and the STOP

istruction must be inserted.

When the STOP instruction is performed, the

control of the algorithm goes back to the CU.
