18.10 Drawing Processing

After the calculation of coordinates by the geometry engine, MB86R02 'Jade-D' draws data in the

drawing frame in the graphics memory that finally uses the drawing coordinates (device coordinates).

Drawing frame is treated as 2D coordinates with the origin at the top left as shown in the figure below.

The maximum coordinates is 4096 × 4096. Each drawing frame is located in the Graphics Memory by

setting the address of the origin and resolution of X direction (size). Although the size of Y direction

does not need to be set, Y coordinates which are max. at drawing must not be overlapped with other

area. In addition, at drawing, specifying the clip frame (top left and bottom right coordinates) can

prevent the drawing of images outside the clip frame.
