Value
“Choosing and Loading Coefficients” on page
Choose the number of bits per color plane.
Choose the number of color planes sent in parallel.
Choose the number of color planes sent in sequence.
Turn on to enable runtime control of the image size. If you do not
turn on this option, the Scaler II IP core does not respond to the
resolution changes in control packets; and the input and output
resolutions are set to the maximum values you specify.
Choose the maximum width for the input frames (in pixels).
Choose the maximum height for the input frames (in pixels).
Choose the maximum width for the output frames (in pixels).
Choose the maximum height for the output frames (in pixels).
Turn on to use the 4:2:2 data format. Turn off to use the 4:4:4
video format.
Turn on if the input video does not contain vertical blanking.
Choose the scaling algorithm. For more information about these
options, refer to
Turn on if you want the output frame height to be less than or
equal to the input frame height, which reduces the size of the line
buffer by one line.
If the input height becomes less than the specified output height
for any reason, the output video is undefined but it should still
have the correct dimensions and the core should not crash.
Turn on to force the bicubic and polyphase algorithms to share the
same horizontal and vertical scaling coefficient data.
Choose the number of vertical filter taps for the bicubic and
polyphase algorithms.
Choose the number of vertical filter phases for the bicubic and
polyphase algorithms.
Choose the number of horizontal filter taps for the bicubic and
polyphase algorithms.
Choose the number of horizontal filter phases for the bicubic and
polyphase algorithms.
