10.1. Clipper II Parameter Settings

Table 35.  Clipper II Parameter Settings
Parameter Value Description
Maximum input frame width 32–8192, Default = 1920 Specify the maximum frame width of the clipping rectangle for the input field (progressive or interlaced).
Maximum input frame height 32–8192, Default = 1080 Specify the maximum height of the clipping rectangle for the input field (progressive or interlaced).
Bits per pixel 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.
Number of pixels in parallel 1, 2, 4, 8 Select the number of pixels in parallel.
Color planes transmitted in parallel On or Off Select whether to send the color planes in parallel or serial. If you turn on this parameter, and set the number of color planes to 3, the IP core sends the R’G’B’s with every beat of data.
Run-time control On or Off Turn on if you want to specify clipping offsets using the Avalon-MM interface.
Note: When you turn on this parameter, the Go bit gets deasserted by default. When you turn off this parameter, the Go is asserted by default.
Clipping method
  • OFFSETS
  • RECTANGLE
Specify the clipping area as offsets from the edge of the input area or as a fixed rectangle.
Left offset 0–8192, Default = 0 Specify the x coordinate for the left edge of the clipping rectangle. 0 is the left edge of the input area.
Note: The left and right offset values must be less than or equal to the input image width.
Top offset 0–8192, Default = 0 Specify the y coordinate for the top edge of the clipping rectangle. 0 is the top edge of the input area.
Note: The top and bottom offset values must be less than or equal to the input image height.
Right offset 0–8192, Default = 0 Specify the x coordinate for the right edge of the clipping rectangle. 0 is the right edge of the input area.
Note: The left and right offset values must be less than or equal to the input image width.
Bottom offset 0–8192, Default = 0 Specify the y coordinate for the bottom edge of the clipping rectangle. 0 is the bottom edge of the input area.
Note: The top and bottom offset values must be less than or equal to the input image height.
Width 32–8192, Default = 32 Specify the width of the clipping rectangle. The minimum output width is 32 pixels.
Height 32–8192, Default = 32 Specify the height of the clipping rectangle. The minimum output height is 32 pixels.
Add extra pipelining registers On or Off Turn on this parameter to add extra pipeline stage registers to the data path. You must turn on this parameter to achieve:
  • Frequency of 150 MHz for Cyclone III or Cyclone IV devices
  • Frequencies above 250 MHz for Arria II, Stratix IV, or Stratix V devices
