Abstract
The integration of Video and Graphics Rasterization along with associated functional blocks provides a balanced MultiMedia/Graphics solution to the technology/bandwidth problem of today's higher density memories. Video rasterization, graphic rasterization, and window identifier functionality are contained on the same chip, fast Random Access Memory for each is provided for each, and the wide bus and high speed accesses to within the chip are shared and contained. The problem is therefore solved in a manner beneficial to both rasterization and video components of Multi-Media and Graphics. Window identification and control functions are added into the memory module, thus permitting both video and graphics rasterization functionality to be closely coupled to an independent high speed SRAM within the Memory Module, and thus applying the full internal wide bus bandwidth of the Frame Buffer memory to both real time video Multi-Media and graphics rasterization functions.
