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.
