3.7.1 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 DVI interface (Chrontel Ch7009
converter), 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.
3.7.2 Features
z
The SBC82810 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 1600x1200 at 85-Hz refresh and
up to 2048x1536 at 75-Hz refresh. The Analog display port can
be driven by Pipe A or Pipe B.
