5.1 Introduction
5.1 Graphic Controller
The 852GM provides a highly integrated graphics accelerator
delivering high performance 2D, 3D, and video capabilities. With its
interfaces to UMA using a DVMT configuration, an analog display
(CRT port), a LVDS port for digital LCD connection and optional
second LVDS LCD interface (via Chrontel CH7305 converter on
AX93200), the 852GM can provide a complete graphics solution. The
852GM also provides 2D hardware acceleration for block transfers of
data (BLTs). Performing these common tasks in hardware reduces
CPU load, and thus improves performance. High bandwidth access to
data is provided through the system memory interface. The 852GM
uses Tiling architecture to increase system memory efficiency and
thus maximize effective rendering bandwidth. The Intel 852GM
GMCH improves 3D performance and quality with 3D Zone rendering
technology. The Intel 852GM GMCH also supports Video Mixer
rendering and Bi-Cubic filtering.
5.2 Features
z The STX88810 adapts Intel 852GM GMCH provides three
display ports, one analog and two digital. With these interfaces,
the GMCH can support for a progressive scan analog monitor, a
dedicated single/dual channel LVDS LCD panel and a converted
LVDS LCD interface through DVO channel. Each port can
transmit data according to one or more protocols. The data that
is sent out the display port is selected from one of the two
possible sources, Pipe A or Pipe B.
z Intel 852GM GMCH has an integrated 350-MHz, 24-bit
RAMDAC that can directly drive a progressive scan analog
monitor pixel resolution up to 2048 x 1536 at 75-Hz refresh. The
Analog display port can be driven by Pipe A or Pipe B.
