High-performance
64-bit 3D graphic & video accelerator |
| |
|
Based
on the new S3 Trio64V2/DXä graphics/video accelerator, a
high-performance 170 MHz true-color RAMDAC and an
enhanced 64-bit graphics accelerator core, the
Virtual V2 delivers the next level of
acceleration required for the most popular
multimedia applications.
The S3 Trio64V2/DXä
accelerators is built on the proven performance
of the Trio64V+ accelerator, with several
advanced engineering innovations including better
memory bandwidth management, faster memory access
and higher memory clock support.
All display applications that require
high-quality video playback or live video input
capability, can take advantage of the new
features. The Virtual V2 brings high-quality
hardware assisted video playback incorporating an
enhanced version of S3’s Streams Processor
technology which provides full-screen playback of
Indeo and Cinepak movies at up to 30 frames per
second.
The Virtual V2 accelerates/enhances software
MPEG-1/Indeo/Cinepak video playback by providing
arbitrary scaling with high quality bilinear (X
and Y) interpolation and color space conversion
(RGB to YUV). Since these tasks are performed in
hardware, the CPU is relieved of a substantial
overhead which produces a considerable
performance improvement.
Additionally, the Virtual V2 provides full
support for Microsoft’s DirectDraw
technology allowing to fully utilize the
multimedia capabilities found in business
applications .
The
Virtual V2 uses EDO
(Extended Data Output) DRAM, a type of
DRAM that is faster than conventional DRAM.
Unlike conventional DRAM which only allows one
byte to be read at a time, EDO DRAM can copy an
entire block of memory to its internal cache.
While the processor is accessing this cache, the
memory can collect a new block to send. |
