Example of LHL coding
Example 1:
LHL = 33h = 001100 11b
LHL(7:3) = 1100b = 12d
LHL(1:0) = 11b = 3d
This leads to:
Mantissa (57 - T
Fraction (57 - T
Therefore:
(57 - T
and T
Example 2:
57 - T
LHL(1:0) = rounded(4*0.21d) = 1d
LHL(7:2) = Mantissa (36.21d) = 36d = 24h
Therefore LHL(7:0) = 10010001 = 91h
Example 3:
57 - T
LHL(1:0) = rounded(4*0.90d) = 4d
The carry must be propagated to the mantissa:
LHL(7:2) = Mantissa (36.90d) + 1 = 37d =
Therefore LHL(7:0) = 10110000 = A0h
