About DP550

This component is a model of the DP550 Display Processor. Connect it to a visualization component to view LCD output. This is the single display configuration of DP550. For the dual display configuration, use DP550x2.

The model provides the following functionality:

  • All RGB and YUV format parsing.
  • Color adjustment in Display Engine (DE).
  • Nearest neighbor scaling.
  • All layers.
  • Alpha blending.
  • Memory writeback.
  • Inverse gamma adjustment.
  • Basic layer (overlay) and register security semantics.

The model has the following limitations:

  • No support for polyphase scaling algorithm. Falls back to nearest neighbor when configured to do so.
  • No support for 3D or interlaced video.
  • No support for image enhancing functionality.
  • No colorspace conversion support.
  • No support for two plane YUV memory writeback.
