18 Graphics Display Controller (GDC)

The embedded graphics core implemented in the MB86R02 'Jade-D' contains two display controllers

which are upwards compatible to the MB86296 (Coral PA) GDC.

• Display controllers

The MB86R02 'Jade-D' has two display controllers that are compatible with the Coral PA.

This GDC supports XGA (1024 × 768 pixels) display, 6-layer overlay, left/right split display, wrap-

around scrolling, double buffers and translucent display.

• Digital video capture

The MB86R02 'Jade-D' has two video capture units that are compatible with the Coral PA.

The digital video capture units can store digital video data such as TV in graphics memory and

display drawn images and video images on the same screen.

• Geometry Engine

The Geometry Engine executes geometry processing and is basically compatible with Coral PA.

Display lists created for Coral series (MB86293 - MB86296) GDCs can be drawn. When intensive

geometric operations processing such as coordinate conversions or clipping are performed by this

GDC, the workload of a CPU can be dramatically reduced.

• 2D and 3D Drawing

The drawing functionality of MB86R02 'Jade-D' is compatible to that of the Coral PA . It can draw

data using display lists created for Coral series GDCs(MB86293 - MB86296).

The MB86R02 'Jade-D' also supports 3D rendering, such as texture mapping with perspective

collection and Gouraud shading, alpha blending and anti-aliasing for drawing smooth lines.

Little endian is supported by the Jade-D GDC in the same way as for Coral PA.

For 32 bit access, both Little endian and Big endian access are handled using the same byte

ordering in the GDC.
