With the widely development of consumer
electronics, 3D graphics have been in high demand in
embedded systems, such as PDA, mobile phone and car
navigation system. 3D graphics rendering is
computation-intensive, and in embedded system a
signal CPU can not offer enough computation power
and only can render a simple scene, so the quality of
image is poor and the speed of rending is slow, it dose
not meet the requirements of real-time interaction. For
solving these issues, the embedded 3D graphics
accelerators [1-3] have been developed.
