DP550x2 - about

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

Functions:

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.

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.
