5.3.4.2 TABLE EXAMPLE 2: COMPRESSED TABLE. In Example 2 (see Figure 5-8), the
data from Example 1 has been compressed by limiting the maximum value of the indepen-
dent variable. Instead of the range 0 X = 65535, X is limited to 0 X 1023. The table has
been compressed to only five entries, but up to 256 levels of interpolation are allowed
between entries.
Since the table is reduced from 257 to 5 entries, independent variable X must be scaled
appropriately. In this case the scaling factor is 64, and the scaling is done by a single instruc-
tion:
LSR.W #6,Dx
Extreme table compression with many levels of interpolation is
possible only with highly linear functions. The table entries within
the range of interest are listed in Table 5-14.
