Abstract
Graphics processors and methods are described that encompass numerous substructures including specialized subsystems, subprocessors, devices, architectures, and corresponding procedures. Embodiments of the invention may include one or more of deferred shading, a bled frame buffer, and multiple-stage hidden surface removal processing, as well as other structures and/or procedures. Embodiments of the present invention are designed to provide high-performance 3D graphics with Phong shading, subpixel anti-aliasing, and texture- and bump-mappings.
