10.2. Chroma Key IP Parameters
The IP offers compile-time parameters.
Parameter | Values | Description |
---|---|---|
Video Data Format | ||
Number of pixels in parallel | 1 to 8 | Select the number of pixels in parallel. |
Number of color planes | 1 or 3 | Select the number of input color planes per pixel. (Output color planes are N+1 for carriage of alpha channel) |
Bits per color sample | 8 to 16 | Select the number of bits per color sample. |
Lite mode | On or off | Turn on to use the lite variant of the Intel FPGA Streaming Video protocol. |
Control | ||
Memory-mapped control interface | On or off | Turn on to specify the pixel matching ranges and alpha values for pixel tagging. The memory-mapped control interface is mandatory in lite mode. |
Separate clock for control interface | On or off | Turn on to enable a separate clock for the control interface. |
Chroma Key Behavior | ||
Constant Alpha Mode | On or off | Turn on for constant alpha mode. |
Constant Alpha Tag | 0 to 65535 | If Constant Alpha Mode is on, the IP appends the Constant Alpha Tag value to each pixel. |
General | ||
Debug features | On or off | Turn on for debug features (not applicable for lite mode). |
Pipeline Ready | On or off | Turn on to pipeline the Tready signal. |
