Pass 2 of Two-Pass Operation
Pass 2 of the two-pass operation
performs vertical filtering on an image
as shown in Figure 10. This mode is
selected by loading M
1-0
with “11.” In
this example, a vertical filter with a
kernel size of 3 pixels is desired.
Loading K
3-0
with “0010” selects a
kernel size of 3. The first pixel se-
lected is determined by x
0
and y
0
. In
this example, the first pixel is (0,0). In
this case, the LF2301s should address
consecutive pixels during each pixel
walk. For this to occur, FOV must be
set to 1 (F
2-0
loaded with “001”).
After the last pixel of a pixel walk has
been selected, the next pixel address
is determined by adding dx/du to the
current X address and by adding
dy/du to the current Y address
(unless the kernel just completed was
the last for that line). At the end of
the first pixel walk, pixel (0,2) is
addressed. Since the first pixel of the
next pixel walk should be (1,0), dx/du
is selected to be 1 and dy/du is selected
to be -2. After the last pixel of the last
pixel walk on the first line has been
selected, the first pixel address of the
second line is determined by adding
dx/dv to x
0
and by adding dy/dv to
y
0
. Since the first pixel of the first
pixel walk on the second line should be
(0,1), dx/dv is selected to be 0 and
dy/dv is selected to be 1. Second
order differential terms are not used
in this filter and are therefore set to 0.

UMIN and VMIN are both selected to
be 5. UMAX and VMAX are both
selected to be 6. Table 11 shows the
values loaded into all Parameter
Registers. Table 12 shows the ITS
outputs for the Pass 2 of a Two-Pass
operation.
1 = 1st pixel of 1st walk,
2 = 1st pixel of 2nd walk, etc.
