Example 1:

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

is codified by the following instructions:

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

IF (Input3 IS Mbf1 AND Input4 IS NOT Mbf15) OR (Input1 IS Mbf6 OR Input6 IS NOT Mbf14) THEN Crisp2

At the end of the fuzzy rule, by using the instruction OUT

RAM_reg, a byte is written. Afterwards, the

control of the algorithm returns to the CU.

LDN 1 1

calculates the NOT

α value of Input

1 with Mbf1 and stores the result in internal registers

LDP 4 12

fixes the

α value of Input

4 with Mbf12 and stores the result in internal registers

FZAND

implements the operation AND between the results obtained with the previous instructions

LDK

stores the result of the previous operation in internal DPU registers

LDP 3 8

fixes the

α value of Input

3 with Mbf8 and stores the result in internal registers

FZOR

implements the operation OR between the results obtained with the previous instructions

CON

crisp1 multiplies the result of the last Ω operation with the crisp value crisp1

LDP 3 1

fixes the

α value of Input

3 with Mbf1 and stores the result in internal registers

LDN 4 15

calculates the NOT

α value of Input

4 with Mbf15 and stores the result in internal registers

FZAND

implements the operation AND between the results obtained with the previous instructions

SKM

stores the result of the previous operation in register M

LDP 1 6

fixes the

α value of Input

1 with Mbf6 and stores the result in internal registers

LDN 2 14

calculates the NOT

α value of Input

6 with Mbf14 and stores the result in internal registers

FZOR

implements the operation OR between the results obtained with the previous instructions

LDK

stores the result of the previous operation in internal DPU registers

LDM

copies the value of the register M in internal DPU registers

FZOR

implements the operation OR between the last two values stored in DPU registers

CON

crisp2 multiplies the result of the last Ω operation with the crisp value crisp2
