10.2. Chroma Resampler IP Parameters

The IP offers compile- and run-time parameters.
Parameter Value Description
Video data format
Lite mode On or off Turn on to use the Lite variant of the Intel FPGA Streaming Video protocol.
Bits per color sample 8 to 16 Select the number of bits per color sample.
Input pixels in parallel 1, 2, 4, 6, 8 Select the number of pixels transmitted every clock cycle at the input interface.
Output pixels in parallel 1, 2, 4, 6, 8 Select the number of pixels transmitted every clock cycle at the output interface.
Disable flush/fill between frames On or off Turn on to turn off the flush and refill of the line buffer between frames.
Maximum field width 1 to 16384 Set the maximum supported field width.
Chroma sampling support
4:2:0 passthrough On or off Turn on for passthrough of 4:2:0 chroma sampled fields.
4:2:0 to 4:2:2 conversion On or off Turn on for conversion from 4:2:0 chroma sampling at the input to 4:2:2 chroma sampling at the output.
4:2:0 to 4:4:4 conversion On or off Turn on for conversion from 4:2:0 chroma sampling at the input to 4:4:4 chroma sampling at the output.
4:2:2 passthrough On or off Turn on for passthrough of 4:2:2 chroma sampled fields.
4:2:2 to 4:2:0 conversion On or off Turn on for conversion from 4:2:2 chroma sampling at the input to 4:2:0 chroma sampling at the output.
4:2:2 to 4:4:4 conversion On or off Turn on for conversion from 4:2:2 chroma sampling at the input to 4:4:4 chroma sampling at the output.
4:4:4 passthrough On or off Turn on for passthrough of 4:4:4 chroma sampled fields.
4:4:4 to 4:2:0 conversion On or off Turn on for conversion from 4:4:4 chroma sampling at the input to 4:2:0 chroma sampling at the output.
4:4:4 to 4:2:2 conversion On or off Turn on for conversion from 4:4:4 chroma sampling at the input to 4:2:2 chroma sampling at the output.
Horizontal resampling settings
Horizontal resampling algorithm Nearest Neighbor, Bilinear, Filtered Select which resampling algorithm to use for all horizontal chroma resampling operations.
Horizontal chroma siting Left, Center Select the expected horizontal chroma siting for fields received at the input interface.
Horizontal luma adaptive resampling On or off Turn on for the luma adaptive algorithm for horizontal resampling conversions. Only if you select Filtered.
Vertical resampling settings
Vertical resampling algorithm Nearest Neighbor, Bilinear, Filtered Select which resampling algorithm to use for all vertical chroma resampling operations.
Vertical chroma siting Top, Center Select the expected vertical chroma siting for fields received at the input interface
Vertical luma adaptive resampling On or off Turn on for the luma adaptive algorithm for vertical resampling conversions. Only if you select Filtered.
Control settings
Memory-mapped control interface On or off Turn on to for the Avalon memory-mapped control agent interface and allow runtime configuration via the register map. You must have the Avalon memory-mapped control agent interface if you turn on Lite mode.
General
Pipeline ready signals On or off Turn on to add extra pipeline registers to the AXI4-S tready signals.
Separate clock for control interface On or off Turn on for a separate clock for the control agent interface.
Debug features On or off Turn on for readback of writeable registers via the control agent interface.
