This section provides a general description of each MegaCore function in the Video
and Image Processing Suite.
The 2D FIR Filter MegaCore function performs 2D convolution using matrices of 3×3,
5×5, or 7×7 coefficients. The 2D FIR Filter retains full precision throughout the
calculation while making efficient use of FPGA resources. With suitable coefficients,
the 2D FIR Filter can perform operations such as sharpening, smoothing, and edge
detection. You can configure the 2D FIR Filter to change coefficient values at run time
with an Avalon-MM slave interface.
The 2D Median Filter MegaCore function applies 3×3 or 5×5 pixel median filters to
video images. Median filtering removes speckle noise and salt-and-pepper noise
while preserving the sharpness of edges in video images.
The Alpha Blending Mixer MegaCore function mixes together up to 12 image layers.
The Alpha Blending Mixer supports both picture-in-picture mixing and image
blending. Each foreground layer can be independently activated and moved at run
time using an Avalon-MM slave interface.
The Chroma Resampler MegaCore function resamples video data to and from
common sampling formats. The human eye is more sensitive to brightness than tone.
Taking advantage of this characteristic, video transmitted in the Y’CbCr color space
often subsamples the color components (Cb and Cr) to save on data bandwidth.
The Clipper MegaCore function clips video streams. You can configure the Clipper at
compile time or optionally at run time using an Avalon-MM slave interface.
The Clocked Video Input MegaCore function converts clocked video formats (such as
BT656, BT1120, and DVI) to Avalon-ST Video. You can configure the Clocked Video
Input at run time using an Avalon-MM slave interface.
The Clocked Video Output MegaCore function converts Avalon-ST Video to clocked
video formats (such as BT656, BT1120, and DVI). You can configure the Clocked Video
Output at run time using an Avalon-MM slave interface.
