8.1 Introduction
The onboard ATI 3D RAGE LT PRO utilizes AGP (Accelerated
Graphics Port) bus to achieve rich 3D and video graphics display. It
enables 3D graphics capabilities including support for z-buffering,
alpha blending and faster texture mapping. Onboard TV-out
connectors support S-VHS and RCA specifications. The unique
features of the 3D RAGE LT PRO are as follows:
•
TV-Out. An integrated TV encoder with on-chip triple-DAC
allows simultaneous CRT/LCD/TV output.
•
Dual CRT Controller Support. Two independent CRT
controllers support two asynchronous simultaneous displays
(LCD/CRT, CRT/TV)
•
Floating-Point Set-up Engine. The 3D RAGE LT PRO
integrates a floating-point set-up engine capable of
processing up to 1.2 million triangles per second. By
off-loading the set-up function from the CPU, allowing it to
focus on 3D geometry and lighting transformation, the 3D
RAGE LT PRO dramatically improves the performance of
the entire 3D pipeline.
•
DVD and Video Support. DVD and video features include
enhanced motion compensation acceleration and a 4-tap
horizontal and 2-tap vertical high quality DVD video scaler,
providing smooth images without the jagged edges common
to today's video products. The scaler provides true color
video display, independent of the graphics mode used.
•
AGP 2X mode. With AGP 2X (133MHz) mode support, the
3D RAGE LT PRO offers a peak bandwidth in excess of
500MB/s, which is twice the output of the AGP 1X (66MHz)
mode. It also supports AGP's pipeline and sideband
protocols
bandwidth that is critical to the enhanced 3D and video
performance.
