The Test Pattern Generator MegaCore function supports a wide range of resolutions
and color spaces with either a sequential or parallel data interface.
In all combinations of color space and subsampling that are allowed, the stream of
pixel data is of a type consistent with the conventions adopted by the other MegaCore
functions in the Video and Image Processing Suite.
The Test Pattern Generator MegaCore function can output streams of pixel data of the
types shown in
The Test Pattern Generator cannot produce interlaced streams of pixel data with an
odd frame height. To create interlaced video streams where F0 fields are one line
higher than F1 fields, Altera recommends feeding Test Pattern Generator progressive
video output into the Interlacer MegaCore function.
