25.3. Avalon-ST Video Stream Cleaner Parameter Settings
|Bits per color sample||4–20, Default = 8||Select the number of bits per color plane.|
|Number of color planes||1–4, Default = 2||Select the number of color planes per pixel.|
|Color planes transmitted in parallel||On or Off||Select whether to send the color planes in parallel or sequence (serially).|
|Number of pixels in parallel||1, 2, 4, 8||Select the number of pixels transmitted per clock cycle.|
|Maximum frame width||32–8192, Default = 1920||Specify the maximum frame width allowed by the core. The Avalon-ST Video Stream Cleaner removes any frames above the specified width from the data stream.|
|Maximum frame height||32–8192, Default = 1080||Specify the maximum frame height allowed by the core. The Avalon-ST Video Stream Cleaner removes any frames above the specified height from the data stream.|
|How user packets are handled||
If you design does not require the Clipper II IP core to propagate user packets, then you may select to discard all user packets to reduce ALM usage.
If your design guarantees there will never be any user packets in the input data stream, then you further reduce ALM usage by selecting No user packets allowed. In this case, the Clipper II IP core may lock if it encounters a user packet.
|Minimum frame width||32–8192, Default = 32||Specify the minimum frame width allowed by the core. The Avalon-ST Video Stream Cleaner removes any frames below the specified width from the data stream.|
|Minimum frame height||32–8192, Default = 32||Specify the minimum frame width allowed by the core. The Avalon-ST Video Stream Cleaner removes any frames below the specified height from the data stream.|
|Enable control slave port||On or Off||Turn on to enable an Avalon-MM control slave port where the error count values can be read and reset.|
|Only clip even numbers of pixels from the left side||On or Off||Frames with widths that are non-integer multiples of the width modulo check value are clipped to the nearest integer multiple. They are clipped as equally as possible on the left and right edges of the image.
Turning on this parameter forces the clip on the left edge of the image to be an even number of pixels. The even number is necessary to prevent color swap for 4:2:2 formatted data.
|Width modulo check value||1, 2, 4, 8, 16, or 32||Specify the width modulo check value.|
|Remove interlaced fields larger than 1080i||On or Off||Turn on to remove interlaced field packets larger than 1080i|
|Register Avalon-ST ready signals||On or Off||
Turn on to add extra pipeline stage registers to the data path.
