Video Memory Interface
The memory controller subsystem of the ATI 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 way that ensures display integrity and
maximum CPU/coprocessor drawing performance.
The board supports an 8 MB (512Kx32bitx4 Banks) SDRAM device for video memory.
