22. Test Pattern Generator II IP Core

The Test Pattern Generator II IP core produces an Avalon-ST compliant output stream containing one of five possible fixed test images. The IP core enables you to adjust the output resolution, color space, subsampling, and selected test patterns at run time.You can use this IP core during the design cycle to validate a video system without the possible throughput issues associated with a real video input.
The Test Pattern Generator II IP core offers the following features:
  • Supports Avalon-ST Video protocol, including variable color and subsampling interfaces.
  • Produces data on request and consequently permits easier debugging of a video data path without the risks of overflow or misconfiguration associated with the use of the Clocked Video Input IP cores or of a custom component using a genuine video input.
  • Supports up to 8 pixels per cycle.
