Protocol Converter Intel® FPGA IP Parameters
The IP offers compile-time parameters
Name | Values | Description |
---|---|---|
Bits per color sample | 8 to 16 | Number of bits that represent each color sample |
Number of color planes | 1 to 4 | Number of colors per pixel |
Number of pixels in parallel | 1, 2, 4 or 8 | Number of pixels transmitted per clock cycle |
YCbCr 444 colour swap | On or off | Turn on to automatically correct for the color plane ordering differences between Avalon Streaming Video and Intel FPGA Streaming Video when transmitting YCbCr data with 4:4:4 chroma |
Memory mapped control interface | On or off | Turn on to allow the Avalon memory-mapped control agent interface to update settings at run time |
Separate clock for control interface | On or off | Turn on for a separate clock domain for the Avalon memory-mapped control agent interface |
Debug features | On or off | Turn on for the debugging features of the Avalon memory-mapped control agent interface |
Pipeline ready signals | On or off | Turn on to add extra pipeline registers to the AXI4-Stream or Avalon Streaming ready signals. Turning on this option may make it easier to close timing for the protocol converter and achieve a higher operation clock frequency, but may contribute to additional ALM usage. |
Input protocol variant | Avalon Streaming Video or Intel FPGA Streaming Video Lite | Select the protocol for the input interface |
Output protocol variant | Avalon Streaming Video or Intel FPGA Streaming Video | Select the protocol for the output interface |
How Avalon-ST Video user packets are handled | No user packets expected at the input or Discard all user packets received | Select how user packets are handled if the input protocol is Avalon Streaming Video. If you do not expect the input stream to contain any user packets, you can select No user packets expected at the input and save the ALM resources required to discard these packets |
Video color space | RGB or YCbCr | If the input protocol is Avalon Streaming Video and you do not turn on Avalon memory-mapped control agent interface, you must specify the color space of the incoming video |
Video chroma sampling | 444, 422 or 420 | If the input protocol is Avalon Streaming Video and you turn off Avalon memory-mapped control agent interface, you must specify the chroma sampling of the incoming video |
Enable low latency mode | On or off | If the input protocol is Intel FPGA Streaming Video this parameter determines the behaviour of the Protocol Converter at the end of each video frame. |
