GRAPHICS 2D
OVERVIEW
FIMG-2D is a 2D graphics accelerator that supports three types of primitive drawings: Line/Point Drawing, Bit
Block Transfer (BitBLT) and Color Expansion (Text Drawing).
Rendering a primitive takes two steps: 1) configure the rendering parameters, such as foreground color and the
coordinate data, by setting the drawing-context registers; 2) start the rendering process by setting the relevant
command registers.
