PLOTTING PROCESSOR FOR HIGH-PERFORMANCE THREE-DIMENSIONAL GRAPHIC ACCELERATOR

摘要

PURPOSE: To improve the performance of a graphic system by receiving a plotting packet storing a pair of geometrical form parameters from a floating point processor, regulating the geometrical form parameters based on an interleave value corresponding to the plotting processor and generating a pair of pixels corresponding to a geometrical form based on these values. CONSTITUTION: The rendering of a three-dimensional geometrical form object is performed by executing edge walking and scan interpolating functions through a three-dimensional geometrical form pipeline 200, and a plotting processor 50 for graphic accelerator is provided for directly executing a pixel function through a port pipeline 220. The plotting processor 50 performs the rendering of pixels and forms an interleave bank composed of plural interleave type frame buffers by performing processing to the pixel function.
