22.4. Test Pattern Generator II Parameter Settings

Table 71.  Test Pattern Generator II Parameter Settings
Parameter Value Description
Bits per color sample 4-20, Default = 8 Select the number of bits per pixel (per color sample).
Number of pixels in parallel 1, 2, 4, or 8 Select the number of pixels transmitted or received in parallel.
Color planes transmitted in parallel On or Off This function always produces three color planes but you can select whether they are transmitted in sequence or in parallel. Turn on to transmit color planes in parallel; turn off to transmit color planes in sequence.
Output format 4:4:4, 4:2:2, 4:2:0, Variable, or Monochrome Select the format/sampling rate format for the output frames.
Note: The IP core does not support odd heights or widths in 4:2:0 mode and odd widths in 4:2:2 mode.
Maximum frame width 32-8192, Default = 1920 Specify the maximum width of output fields or frames. This parameter is used as the default start-up value only if you turn on run-time control.
Maximum frame height 32-8192, Default = 1080 Specify the maximum height of output fields or frames. This parameter is used as the default start-up value only if you turn on run-time control.
Default interlacing
  • Progressive output
  • Interlaced output (F0 First)
  • Interlaced output (F1 First)
Specify whether to produce progressive or interlaced video output. For interlaced output, you may select to start with either an F0 field first or an F1 field first.

If you turn on run-time control, you can change your selection during run time using the Avalon-MM control slave interface.

Run-time control On or Off Turn on to enable run-time control of the image size, progressive/interlaced selection, and test pattern selection.
Note: When you turn on this parameter, the Go bit gets deasserted by default. When you turn off this parameter, the Go asserts by default.
Reduced control register readback On or Off

If you do not turn on this parameter, the values of all the registers in the control slave interface can be read back after they are written.

If you turn on this parameter, you won't be able to read back the values written to the register map through the Avalon-MM control slave interface. This option reduces overall resource usage.

Pipeline dout ready On or Off

Turn on to add extra pipeline stage registers to the Avalon-ST ready signals.

You must to turn on this option to achieve the frequency of 300 MHz for Intel® Arria® 10 devices.

Enable border for bar patterns On or Off Turn to enable the black border on color bar, grayscale bar, and black and white bar test patterns.

If you turn on run-time control, you can change your selection during run time using the Avalon-MM control slave interface.

Uniform R or Y 0-255, Default = 16

Specifies the default color value of the R or Y plane in all uniform background test patterns.

If you turn on run-time control, you can change your selection during run time using the Avalon-MM control slave interface.

Uniform G or Cb 0-255, Default = 16 Specifies the default color value of the G or Cb plane in all uniform background test patterns.

If you turn on run-time control, you can change your selection during run time using the Avalon-MM control slave interface.

Uniform B or Cr 0-255, Default = 16 Specifies the default color value of the B or Cr plane in all uniform background test patterns.

If you turn on run-time control, you can change your selection during run time using the Avalon-MM control slave interface.

Number of test patterns 1-8, Default = 1 Number of test pattern configurations to enable. Run-time control must be enabled for all values other than 1.
Pattern
  • Color bars
  • Grayscale bars
  • Black and White bars
  • Uniform background
  • SDI pathological
One parameter for each enabled test pattern configuration. This parameter specifies the test pattern to use for each configuration.
Subsampling & Colorspace RGB, YCbCr 4:4:4, YCbCr 4:2:2, YCbCr 4:2:0, or Monochrome One parameter for each enabled test pattern configuration. This parameter specifies the subsampling and color space to use for each configuration.
