摘要

A computing system having a multi-mode parallel graphics rendering subsystem which includes multiple graphics processing pipelines (GPPLs) and automated division of graphics commands and data during automatic mode control. The multi-mode parallel graphics rendering subsystem supports multiple modes of parallel operation selected from the group consisting of object division, image division, and time division. The GPPLs support a parallel graphics rendering process that employs one or more of the object division, image division and/or time division modes of parallel operation in order to execute graphic commands and process graphics data, and render pixel-composited images containing graphics for display on a display device during the run-time of the graphics-based application. The multi-mode parallel graphics rendering subsystem includes a decomposition module, a distribution module and a recomposition module, for supporting the decomposition, distribution and recomposition stages of the graphics rendering process, respectively. The decomposition module includes a division control submodule for automatically processing graphics commands and data for division during the decomposition stage, and controlling the division of the graphics commands and data among the GPPLs, prior to the distribution stage, according to the mode of parallel operation instantiated at any instant during the run-time of the graphics-based application.
