Each video stream can transfer images with the following maximum dimensions.
Multiple video streams can be used to support even more demanding applications.
Dimension
Image size (pixel resolution)
Number of components (taps or bands)
Number of bits/component
The LINX can simultaneously manage:
• Up to 64 video input data streams that have different destinations.
• Two video output streams.
Matrox Oasis can generate interrupts at the start and end of a video stream transfer,
as well as at the end of a specific line within a frame.
Each Oasis link port can operate in a different mode and clock frequency. Slow
targets can regulate the pace of the video stream that they are receiving so that
excess Oasis link port bandwidth is not lost.
Formatters
The formatters can perform the following on the video streams:
• Source and destination alignments (with pixel resolution).
• Plane (component) separation on input streams and merging on output streams.
• Input cropping (also known as input windowing). This allows you to extract a
region of interest (with pixel resolution) from an input stream.
• Horizontal sub-sampling of input and output streams. Integer subsampling factors
from 1 to 16 are supported. (The formatters are not required for vertical
subsampling; this is handled directly by the memory controller.)
• Independent control of horizontal scanning direction for input streams. The
formatters are not required to control the vertical scan direction; this is handled
directly by the memory controller. Control over the scan direction is particularly
useful for reconstructing a proper image from a video source that uses multiple
taps, each with different scanning directions.
