Introduction / Overview

Dual Video Accelerator Engines
To enable true dual independent display, two multimedia engines are implemented in the 69030 graphics
accelerator to provide video acceleration for both display pipelines. These engines support on-the-fly data
conversion from YUV 4:2:2 to 24-bit RGB format, horizontal/vertical interpolation, and color key video
overlay. The 69030 graphics accelerator also provides flexibility in configuring the two engines. Depending
upon the dual display operating mode and application requirements, each engine can be programmed to
provide dedicated video acceleration support for each display pipeline or both engines can be programmed
to support acceleration for either one of the pipelines.

HiQColor
Technology

The 69030 graphics accelerator integrates breakthrough HiQColor
technology. Based on the CHIPS
proprietary Temporal Modulated Energy Distribution (TMED) 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 kind of display quality and color fidelity previously only available
with TFT technology.
Acceleration for All Panels and All Modes
The 69030 graphics engine is designed to support high performance graphics and video acceleration for all
supported display resolutions, display types, and color modes. There is no compromise in performance
when operating in 8, 16, or 24 bpp color modes, allowing true acceleration while displaying up to 16.7M
colors.
The 69030 graphics engine boosts the 2D performance through specialized hardware, which accelerates
the most frequently used 2D GUI operations. This acceleration is supported in all graphics modes up to
1600x1200* and all color depths for both pipelines to support the dual display function.

Television NTSC/PAL Flicker Free Output and Underscan
The 69030 graphics accelerator 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 69030 graphics
accelerator 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/PAL mode.
In order to prevent panning or the loss of data vertically on the television screen, the 69030 graphics
accelerator uses a vertical reduction line dropping interval process by which the entire on-screen data can
be displayed for 640x480 (NTSC) resolution and 800x600 (PAL) resolution.

HiQVideo
Capture/Playback Support
The 69030 graphics accelerator implements a variety of features to deliver high quality, full screen, full
frame-rate video capture playback for MPEG1, MPEG2, V-CD and DVD by using the independent
multimedia capture and display system on-chip. The capture system places data in display memory (usually
off screen) and the display system places the data in a window on the screen.
The capture engine can receive data from either the system bus or from the ZV enabled video port in either
RGB or YUV format. The input data can also be scaled down before storage in display memory. In order
to improve the video playback quality, the 69030 graphics accelerator continuously scales video data with
horizontal and vertical interpolation. Capture of input data may also be double buffered for smoothing and
to prevent image tearing resulting from the display of an unfinished captured frame or field picture. To
