3–19, and
Choose the scaling algorithm. For more information about these options,
refer to
Specify the number of vertical taps.
Specify the number of vertical phases.
Specify the number of horizontal taps.
Specify the number of horizontal phases.
Turn on if you want the fixed-point type that stores the vertical coefficients
to have a sign bit.
Specifies the number of integer bits for the fixed-point type used to store
the vertical coefficients.
Specifies the number of fractional bits for the fixed point type used to
store the vertical coefficients.
Specifies the number of bits to preserve between vertical and horizontal
filtering.
Turn on if you want the fixed-point type that stores the horizontal
coefficients to have a sign bit.
Table 3–20 on page 3–19
Turn on to enable run-time control of the image size. When on, the
input and output size parameters control the maximum values.
When off, the Scaler does not respond to changes of resolution in
control packets.
Choose the required input width in pixels.
Choose the required input height in pixels.
Choose the required output width in pixels.
Choose the required output height in pixels.
Choose the number of bits per pixel (per color plane).
The number of color planes that are sent over one data
connection. For example, a value of 3 for R'G'B' R'G'B' R'G'B' in
serial.
The transmission mode used for the specified number of color
planes.
