 If the 32-bit instruction is used, S
2
will occupy eight consecutive devices.
 Equation: D=[(S
1
–Minimum source value)×(Maximum destination
value–Minimum destination value)]÷(Maximum source value–Minimum source
value)+Minimum destination value
 Relation between the source value in S
1
and the destination value in D:
y=kx+b
y=Destination value (D)
k=Slope=(Maximum destination value–Minimum destination value)÷(Maximum
source value–Minimum source value)
x=Source value (S
1
)
b=Offset =Minimum destination value–Minimum source value×Slope
 After the parameters above are substituted for y, k, x, and b in the equation
y=kx+b, the equation below will be obtained.
y=kx+b=D=kS

+b=Slope×S

＋Offset＝Slope×S

–Minimum source value)＋
Minimum destination value =(S
1
–Minimum source value)×(Maximum destination
value–Minimum destination value)÷(Maximum source value–Minimum source
value)＋Minimum destination value
 If the value in S
1
is greater than the maximum source value, the value in S
1
will
be equal to the maximum source value. If the value in S
1
is less than the
minimum source value, the value in S
1
will be equal to the minimum source
value. After input values and parameters are set, an output curve will be gotten.
