M2/PCI Board Architecture
The M2/PCI™ display controller (board) is a single-
or dual-headed, 8-bit framebuffer with a 10-bit DAC
(digital-to-analog converter).
The figure below shows these significant features of the
board architecture:
• A highly optimized PCI local bus that provides 64-bit,
• 32 MB of DDR SDRAM that supports an 8 bits per pixel
• Supports double buffering, overlay, and stereo
• Can drive two analog displays in portrait or
66 MHz transfers at speeds exceeding 500 MB per second
grayscale or pseudocolor display and a 32 bit per pixel
truecolor display
