Information handling system including mapping of graphics display data to a video buffer for fast updation of graphic primitives |
摘要 |
An information handling system includes a central processor, a read only memory for storing microcode, a random access memory for storing instructions and data processed by the central processor, an I/O adapter for transferring data to and from peripheral devices, a user interface adapter for communicating with user devices such as a keyboard and a cursor control device, and a display adapter for converting data to be displayed to a form suitable for presentation on a display device, the display adapter including a video frame buffer architecture which allows a page mode to be used for fast screen update using commercially available chips wherein independently addressable islands on the chips are individually addressed to increase data transmission bandwidth.
