The Frame Reader MegaCore function reads video frames stored in external memory
and outputs them as a video stream. You can configure the MegaCore function to read
multiple video frames using an Avalon-MM slave interface.
The Frame Buffer MegaCore function buffers video frames into external RAM. The
Frame Buffer supports double or triple buffering with a range of options for frame
dropping and repeating.
The Gamma Corrector MegaCore function corrects video streams for the physical
properties of display devices. For example, the brightness displayed by a cathode-ray
tube monitor has a nonlinear response to the voltage of a video signal. You can
configure the Gamma Corrector with a look-up table that models the nonlinear
function to compensate for the non linearity. The look-up table can then transform the
video data and give the best image on the display.
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.
