The Scaler II MegaCore function currently does not offer the nearest neighbor and
bicubic scaling modes, and the symmetric coefficient functionality is disabled for both
horizontal and vertical coefficients. You must specify the coefficients at run time for
version 10.1. However, you can achieve bicubic scaling by setting the horizontal and
vertical taps to 4 and load bicubic coefficients through the Avalon-MM control port.

Turn on to enable run-time control of the image size. When on, the output
size parameters control the maximum values.
Choose the required output width in pixels.
Choose the required output height in pixels. This value should be the height
of the full progressive frame when outputting interlaced data.
Choose the number of color planes.
Turn on to set colors planes in parallel, turn off to set colors planes in
sequence.
Turn on to enable the alpha ports.
Choose the number of bits used to represent the alpha coefficient.
When a custom function is selected, you can browse for a
comma-separated value file containing custom coefficients. Key in
the path for the file that contains these custom efficients.
Turn on to add extra pipeline stage registers to the data path.
You may need to turn on this option to achieve a frequency of
150 MHz for Cyclone III or Cyclone IV devices, and frequencies
above 250 MHz for Arria II, Stratix IV, and Stratix V devices.
