load bit y of parameter Pa in the stac
k
LDN Pa,y load inverted bit y of parameter Pa in the stack
OUT Pa,y set bit y of parameter Pa to the value loaded in the stack
OUTN Pa,y set bit y of parameter Pa to the stack value and invert it
SET Pa,y if stack is at 1, set bit y of parameter Pa to 1
RES Pa,y if stack is at 1, set bit y of parameter Pa to zero
AND Pa,y the bit loaded into the stack assumes the result of the
logical AND operation between itself and bit y of
parameter Pa
ANDN Pa,y the stack bit assumes the result of the logical AND between
itself and inverted bit y of parameter Pa
OR Pa,y the bit loaded into the stack assumes the result of the OR
between itself and bit y of parameter Pa
ORN Pa,y the stack bit assumes the result of the OR between itself
and inverted bit y of parameter Pa
ADD Pa, Pb, Pc if stack bit is at 1, parameter sum operation is executed,
therefore: Pc = Pa + Pb
SUB Pa, Pb, Pc if stack bit is at 1, subtraction operation is executed on
parameters, therefore: Pc = Pa - Pb
MUL Pa, Pb, Pc if stack bit is at 1, multiplication operation is executed on
parameters, therefore: Pc = Pa ⋅ Pb
DIV Pa, Pb, Pc if stack bit is at 1, division operation is executed on the
parameters, therefore: Pc = Pa / Pb
