 VRender™ 3D is an effective SoC solution for integrating
32 bit micro processor, 3D graphics, 64 poly wavetable, audio,
image capture processor, video codec and related interface circuits,
providing superior 3D graphic performance for applications such
as portable 3D game machine, 3D game phone and other 3D graphic
utilizing machines.
The Competitiveness of VRender™ 3D is 3D graphic performance
and low power consumption. Most 3D graphic chip needs floating
point CPU and very high power consumption. VRender 3D enables
high performance 3D graphic functions at fixed point CPU environment
and low power consumption. |
