With the widely development of consumer
electronics, 3D graphics have been in high demand
and it has also become a very important module in
embedded systems. Recent years more and more
attentions have been paid on 3D graphics rendering.
As we know it is very difficult to achieve real-time
interactive request in the complex 3D graphics
rendering on a signal CPU, therefore a dedicated
graphics processor is need to enhance the rendering
speed. But in embedded system, source is limited and
power is supplied by battery, so that the 3D graphic
processing for mobile environment can not employ the
same algorithm or architecture as in the pc
environment. In this paper, we review a full 3D
graphics pipeline and discuss optimizations of graphics
architecture have been made to overcome the
shortcomings in mobile environment.
