Introduction / Overview
The 69000 is the first product in the CHIPS family of portable graphics accelerator product line that
integrates high performance memory technology for the graphics frame buffer. Based on the proven
HiQVideo
graphics accelerator core, the 69000 combines state-of-the-art flat panel controller capabilities
with low power, high performance integrated memory. The result is the start of a high performance, low
power, highly integrated solution for the premier family of portable graphics products.
High Performance Integrated Memory
The 69000 is the first member of the HiQVideo
family to provide integrated high performance
synchronous DRAM (SDRAM) memory technology. Targeted at the mainstream notebook market, the
69000 incorporates 2MB of proprietary integrated SDRAM for the graphics/video frame buffer. The
integrated SDRAM memory can support up to 83MHz operation, thus increasing the available memory
bandwidth for the graphics subsystem. The result is support for additional high color / high resolution
graphics modes combined with real-time video acceleration. This additional bandwidth also allows more
flexibility in the other graphics functions intensely used in Graphical User Interfaces (GUIs) such as
Microsoft
Windows
Frame-Based AGP Compatibility
The 69000 graphics is designed to be used with either 33MHz PCI, or with AGP as a frame-based AGP
device, allowing it to be used with the AGP interface provided by the latest core logic chipsets.
TM
HiQColor
Technology
The 69000 integrates CHIPS breakthrough HiQColor
technology. Based on the CHIPS proprietary
TMED
(Temporal Modulated Energy Distribution) algorithm, HiQColor technology is a unique process that
allows the display of 16.7 million true colors on STN panels without using Frame Rate Control (FRC) or
dithering. In addition, TMED also reduces the need for the panel tuning associated with current FRC-based
algorithms. Independent of panel response, the TMED algorithm eliminates all of the flaws (such as
shimmer, Mach banding, and other motion artifacts) normally associated with dithering and FRC. Combined
with the new fast response, high-contrast, and low-crosstalk technology found in new STN panels, HiQColor
technology enables the best display quality and color fidelity previously only available with TFT technology.
Versatile Panel Support
The HiQVideo
family supports a wide variety of monochrome and color Single-Panel, Single-Drive (SS)
and Dual-Panel, Dual Drive (DD), standard and high-resolution, passive STN and active matrix TFT/MIM
LCD, and EL panels. With HiQColor
technology, up to 256 gray scales are supported on passive STN
LCDs. Up to 16.7M different colors can be displayed on passive STN LCDs and up to 16.7M colors on 24-
bit active matrix LCDs.
The 69000 offers a variety of programmable features to optimize display quality. Vertical centering and
stretching are provided for handling modes with less than 480 lines on 480-line panels. Horizontal and
vertical stretching capabilities are also available for both text and graphics modes for optimal display of VGA
text and graphics modes on 800x600, 1024x768 and 1280x1024 panels.
Television NTSC/PAL Flicker Free Output
The 69000 uses a flicker reduction process which makes text of all fonts and sizes readable by reducing the
flicker and jumping lines on the display. To accomplish this, the 69000 uses a line buffer and digital filters
to average adjacent vertical lines for odd/even display. The chip also uses both horizontal and vertical
interpolation to make both graphics and text appear "smooth" on the television. This process reduces the
effect of flicker in the NTSC mode.
