The conventional 3D graphic processors for pc work
with high performance CPUs and has unlimited power.
However, mobile devices have the limited source and
the limited power supplied by batteries. So a lot of
researches have been made for satisfying the
performance requirements and overcoming the
shortcomings in mobile terminals. In this paper we
describe the traditional rendering pipeline and its
shortcomings in mobile environments, and then the
optimizations of architectural in mobile environment
are discussed.
