Description
6
Lower Blur Threshold
Specifies the minimum difference between two pixels for a
blurred edge to be detected between the pixels during post
scaling edge-adaptive sharpening. To get the threshold used
internally, this value is multiplied by the number of color
planes per pixel.
7
Upper Blur Threshold
Specifies the maximum difference between two pixels for a
blurred edge to be detected between the pixels during post
scaling edge-adaptive sharpening. To get the threshold used
internally, this value is multiplied by the number of color
planes per pixel.
8
Horizontal
Coefficient Write
Bank
Specifies which memory bank horizontal coefficient writes
from the Avalon-MM interface are made into.
9
Horizontal
Coefficient Read
Bank
Specifies which memory bank is used for horizontal
coefficient reads during data processing.
10
Vertical Coefficient
Write Bank
Specifies which memory bank vertical coefficient writes from
the Avalon-MM interface are made into.
11
Vertical Coefficient
Read Bank
Specifies which memory bank is used for vertical coefficient
reads during data processing.
12
Horizontal Phase
Specifies which horizontal phase the coefficient tap data in the
Coefficient Data
register applies to. Writing to this
location, commits the writing of coefficient tap data. This
write must be made even if the phase value does not change
between successive sets of coefficient tap data.
To commit to an edge phase, write the horizontal phase
number +32768. For example, set bit 15 of the register to 1.
13
Vertical Phase
Specifies which vertical phase the coefficient tap data in the
Coefficient Data
register applies to. Writing to this
location, commits the writing of coefficient tap data. This
write must be made even if the phase value does not change
between successive sets of coefficient tap data.
To commit to an edge phase, write the vertical phase number
+32768. For example, set bit 15 of the register to 1.
14 to 14+N
taps
Coefficient Data
Specifies values for the coefficients at each tap of a particular
horizontal or vertical phase. Write these values first, then the
Horizontal Phase
or
Vertical Phase
, to commit the write.
