Abstract
A graphics system including a custom graphics and audio processor produces exciting 2D and 3D graphics and surround sound. The system includes a graphics and audio processor including a 3D graphics pipeline and an audio digital signal processor. An additional matrix multiplication computation unit connected in cascade with a modelview matrix computation unit can support a piecewise linear version of skinning for skeletal animation modeling. The normalizer connected between the cascaded matrix multiplication computation units can provide normalization to avoid distorted visualization. The additional matrix multiplication computation unit can be used for applications other than skeletal animation modeling (e.g., environment mapping).
