Video Memory Interface
The memory controller subsystem of the Rage XL arbitrates requests from direct memory
interface, the VGA graphics controller, the drawing coprocessor, the display controller, the video
scalar, and hardware cursor. Requests are serviced in a manner that ensures display integrity
and maximum CPU/coprocessor drawing performance.
The S875WP1-E supports an 8 MB SDRAM device for video memory.
