DX/PCI Board Architecture
The DX/PCI™ display controller (board) is a single- or
dual-headed, 8-bit framebuffer with an 8-bit digital
interface.
The figure below shows these significant features of the
board architecture:
• A highly optimized PCI local bus that provides 32-bit or
• 32 MB of DDR SDRAM (double data rate synchronous
• Can drive two digital displays in portrait or landscape
64-bit, 66 MHz transfers at speeds exceeding 500 MB
per second
dynamic random access memory) that supports a
3-megapixel grayscale or pseudocolor display and a
5-megapixel grayscale display
mode on the C3 flat-panel system and two digital
displays in portrait mode on the C5 flat-panel system
