Hardware Description
3.6 Display Interface
3.6.1 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
3300060D
), 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.
3.6.2 Features
z The
3300060
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.
