44.2. Test Pattern Generator IP 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.
|
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 and fields produced at the output. If the selected output subsampling is 4:2:0, the field 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 the bars test pattern. Sets which variant of the bars pattern to use. |
Fixed constant color R/Cr | 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 R color plane if the output is RGB, or the Cr color plane if the output is YCbCr. |
Fixed constant color 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 constant color 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. |
Fixed zone plate coarse scaling factor | 1 to 31 | Only if Memory-mapped control interface is off. Increase this value to increase the size of the zone plate. The value is arbitrary, but Intel recommends a starting value of 14 for HD and 20 for 4k resolutions. |
Fixed zone plate fine tune scaling factor | 1 to 65535 |
Only if Memory-mapped control interface is off. A 16-bit fixed-point value, with 8 bits fractional part. For example, 256 represents a value of 1.0. Increase this value to decrease the size of the zone plate. |
Fixed clock background color (B/Cb component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Select the value the IP uses for the B background color plane if the output is RGB, or the Cb color plane if the output is YCbCr. |
Fixed clock background color (G/Y component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Sets the value the IP uses for the G background color plane if the output is RGB, or the Y color plane if the output is YCbCr. |
Fixed clock background color (R/Cr component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Select the value the IP uses for the R background color plane if the output is RGB, or the Cr color plane if the output is YCbCr. |
Fixed clock font color (B/Cb component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Select the value the IP uses for the B font color plane if the output is RGB, or the Cb color plane if the output is YCbCr. |
Fixed clock font color (G/Y component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Select the value the IP uses for the G font color plane if the output is RGB, or the Y color plane if the output is YCbCr. |
Fixed clock font color (R/Cr component) | 0– (2^ Bits per color sample)-1 | Only if Memory-mapped control interface is off. Select the value the IP uses for the R font color plane if the output is RGB, or the Cr color plane if the output is YcbCr. |
Fixed clock location x-coordinate | 0 to 16383 | Only if Memory-mapped control interface is off. Select the x-location of the top-left pixel of the digital clock. |
Fixed clock location y-coordinate | 0 to 16383 | Only if Memory-mapped control interface is off. Select the y-location of the top-left pixel of the digital clock. |
Fixed clock scale factor | 1 to 65535 | Only if Memory-mapped control interface is off and you select the digital clock test pattern. Selectt the multiplying coefficient to the original digital clock dimensions. |
Fixed clock FPS | 1 to 60 | Only if Memory-mapped control interface is off. Select the number of frames until one second is reached. This parameter does not affect the output video refresh rate). |
Number of test patterns | 1 to 8 | Set the number of test pattern configurations to turn on. |
Core 0 test pattern Core 1 test pattern Core 2 test pattern Core 3 test pattern Core 4 test pattern Core 5 test pattern Core 6 test pattern Core 7 test pattern |
