Abstract
Hardware logic and processing methods for enhanced data manipulation within a graphics display system are described. The graphics display system includes a graphics processor sub-system and a rendering subsystem which are serially connected for pipeline processing of an interleaved stream of commands and data. One or more status bits or XBITs are defined within each rasterizer of a multi-rasterizer rendering sub-system. An XBIT, which may comprise a ZBIT, a UBIT, or an RBIT, etc., provides a mechanism for introducing execution of various logic functions within the rendering sub-system portion of the computer graphics adapter. Corresponding data processing methods are also described.
