DP650x2 component

This section describes the dual display configuration of the DP650 component.

DP650x2 - about

This component is a model of the dual display configuration of the DP650 Display Processor. To view LCD output, connect it to a visualization component.

The model has the following limitations:

  • No support for the polyphase scaling algorithm, it always uses nearest neighbor.
  • No support for 3D or interlaced video.
  • No support for image enhancing functionality.
  • No YUV 2-plane support for memory writeback.
  • No color space conversion support.
