Design Example

The Interlacer MegaCore function converts progressive video to interlaced video by
dropping half the lines of incoming progressive frames. You can configure the
MegaCore function to discard or propagate already-interlaced input. You can also
disable the interlacer at run time to propagate progressive frames unchanged.
The Scaler MegaCore function resizes video streams. The Scaler supports nearest-
neighbor, bilinear, bicubic, and polyphase scaling algorithms. You can configure the
Scaler to change resolutions or filter coefficients, or both, at run time using an Avalon-
MM slave interface.
The Scaler II MegaCore function resizes video streams more efficiently than the Scaler.
The Scaler II reduces the required resources with the support of 4:2:2 chroma data
sampling rate. The Scaler II supports only bilinear and polyphase scaling algorithms.
The Switch MegaCore function allows the connection of up to twelve input video
streams to twelve output video streams and the run-time reconfiguration of those
connections via a control input.
The Test Pattern Generator generates a video stream that displays either still color
bars for use as a test pattern or a constant color for use as a uniform background. You
can use this MegaCore function during the design cycle to validate a video system
without the possible throughput issues associated with a real video input.
A provided design example offers a starting point to quickly understand the Altera
video design methodology, enabling you to build full video processing systems on an
FPGA.

Processing Up Conversion Example
Before releasing a version of each MegaCore function, Altera runs comprehensive
regression tests to verify quality and correctness.
Custom variations of the MegaCore functions exercise various parameter options. The
resulting simulation models are thoroughly simulated and the results verified against
bit-accurate master simulation models.
