13.1 INTRODUCTION
FIMG-2D is a 2D graphics accelerator that supports Bit Block Transfer (BitBLT).
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 accordingly.
