20.2. Test Pattern Generator IP Parameters

The IP offers run time and compile time parameters,
Parameter Value Description
Interface Configuration
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
Number of pixels in parallel 1 to 8 Select the number of pixels in parallel at the output interface.
Output format 4:4:4, 4:2:2, 4:2:0. Variable or Monochrome Select the chroma sampling format for the output interface.
General
Memory mapped control interface On or off Turn on 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 when you turn on Lite mode.
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 read back of writeable registers via the control agent interface.
Pipeline ready signals On or off Turn on to add extra pipeline registers to the AXI4-S tready signals.
Shared configuration
Fixed interlacing 0 to 15 Only if memory mapped control interface is not on. Select if output stream is progressive, interlaced with F0 sent first after reset, or interlaced with F1 sent first after reset. If Lite mode is off, the selected value populates the interlaced identifier field in the output image info packets.
  1. Values 0-7 give progressive output
  2. Values 8-11 give interlaced output with F0 send first
  3. Values 12-15 give interlaced output with F1 sent first
.
Fixed frame width 1 to 16384 Only if memory mapped control interface is off. Select the width of the frames and fields produced at the output. If the selected output subsampling is 4:2:2 or 4:2:0, the frame width must be a multiple of 2.
Fixed frame height 1 to 16384 Only if memory mapped control interface is off. Select the height of the frames produced at the output. If interlaced output is on, the height of each field is half this value. If the selected output subsampling is 4:2:0, the frame height must be a multiple of 2.
Pattern configuration
Fixed bars mode Color, Greyscale, Black and white, Mixed Only if memory mapped control interface is off and you select bars test pattern. Sets which variant of the bars pattern to use.
Fixed R/Cr 0 – (2^ Bits per color sample)-1 Only if memory mapped control interface is off and you select constant color test pattern. Sets the value the IP uses for the R color plane if the output is RGB, or the Cr color plane if the output is YCbCr.
Fixed G/Y 0 – (2^ Bits per color sample)-1 Only if memory mapped control interface is off and you select the constant color test pattern. Sets the value the IP uses for the G color plane if the output is RGB, or the Y color plane if the output is YCbCr.
Fixed B/Cb 0 – (2^ Bits per color sample)-1 Only if memory mapped control interface is off and you select the constant color test pattern. Sets the value the IP uses for the B color plane if the output is RGB, or the Cb color plane if the output is YCbCr.
Number of test patterns 1 to 8 Set the number of test pattern configurations to turn on.
