MEMORY EFFICIENT CELL TEXTURING FOR ADVANCED VIDEO OBJECT GENERATOR |
摘要 |
<p>An improved advanced video object generator with a more efficient cell texturing memory is disclosed. The advanced video object generator includes a data memory for storing cell-by-cell object data for a plurality of objects for retrieval and processing for video display. A vector processor calculates object transformations for translating operator inputs into image orientation control signals for calculating pixel-by-pixel image data. Cell texture address logic determines the memory location to be accessed for retrieval of cell texture data for display. Output logic provides the cell texture data to a span processor which translates the cell texture data into pixel-by-pixel display data for display on a video display device. The disclosed improvement includes at least one data memory hardware map having a plurality of nxn memory locations for storing n2 cell sets of cell texture data. The cell texture output logic reads out two independent n2 cell sets simultaneously which are blended.</p> |
