Parameter
You can create custom coefficient data using third-party tools such as Microsoft Excel
or the MATLAB Array Editor. To do so, click Preview coefficients under Vertical
Coefficient Data and Horizontal Coefficient Data, copy the data from the predefined
coefficient spreadsheet, edit the data with your third-party tool, delete the Phase
column, and store the data in the Coeff columns as a .csv file. Then in the parameter
editor, select Custom from the Filter function list, click Browse, load the .csv file, and
click Preview coefficients to verify the data.

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 run-time 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 at its
point of conversion to the Avalon-ST video protocol.
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.
