Name Specification
Y=H1*U1 + H2*U2 + H3
Y=U1 + U2 + U3 + U4 + U5 + U6
Y=H1*U1*U2
Y=(H1*U1 + H2) / (H3*U2 + H4)
Y=|U1|
If H1=0 then Y=U1, else Y=U2
Y=U1 ∧ U2 ∧ U3 ∧ U4 ∧ U5 ∧ U6
Y=U1 ∨ U2 ∨ U3 ∨ U4 ∨ U5 ∨ U6
Y=U1xorU2
If U1= then Y=1, else Y=0
Y = (U1 ∧ U2 ∧ U3) ∨ (U4 ∧ U5 ∧ U6)
Y = (U1 ∨ U2 ∨ U3) ∧ (U4 ∨ U5 ∨ U6)
If U1=1 then Y=1 if U1 = 0, U2=1 then Y=0
If U1=0, U2=0 then Y=Previous output value
If U1 > H1 *U2 + H2 then Y=1, else Y=0
If U1 < H1 *U2 + H2 then Y=1, else Y=0
If U1 ≥ H1*U2 + H2 then Y=1, else Y = 0

Comparison
When H1=H2=1.0 and H3=0.0, ADD_REAL is an
equivalent instruction.
When H1=1.0, H2= − 1.0 and H3=0.0, SUB_REAL is an
equivalent instruction.
(ADD) is a substitute application.
ADD_REAL
MUL_REAL
When divided by 0 (divisor = 0), output value is retained.
When H1=H3=1.0 and H2=H4=0.0, DIV_REAL is an
equivalent instruction and (DIV) is a substitute
application. (However, when divided by 0, the output
becomes ±∞ or 0 depending on the dividend.)
