A multi-mode parallel graphics rendering and display system supporting real-time graphics rendering and display operations using a graphics hub device. The system includes a CPU memory space, one or more CPUs for executing graphics-based applications, and a multi-mode parallel graphics rendering system (MPGRS) supporting multiple modes of parallel operation including object division, image division, and time division. The MMPGRS includes a plurality of graphic processing pipelines (GPPLs) that support a parallel graphics rendering process employing one or more modes of parallel operation. Each mode of parallel operation includes at least a decomposition stage, a distribution stage and a recomposition stage, and the MMPGRS also includes a decomposition module for supporting the decomposition stage, a distribution module for supporting the distribution stage, a recomposition module for supporting the recomposition stage, and a graphics hub device (GHD) for interconnecting the CPU memory space with the GPPLs, and supporting basic functionalities of the distribution and recomposition modules during the run-time of the graphics-based application. An automatic mode controller automatically controls the mode of parallel operation of the parallel graphics rendering subsystem during the run-time of the graphics-based application.
