VT8606 / TwisterT
PCI master read latency and DRAM utilization. Delay transaction and read caching mechanisms are also implemented for further
improvement of overall system performance.
TwisterT also integrates S3’s Savage4 graphics accelerator into a single chip. TwisterT brings mainstream graphics
performance to the Value PC with leading-edge 2D, 3D and DVD video acceleration into a cost effective package. Based on its
capabilities, TwisterT is an ideal solution for the consumer, corporate mobile users and entry level professionals.
The industry’s first integrated AGP 4X solution, TwisterT combines AGP 4X performance with S3’s DX6 texture compression
(S3TC) and massive 2Kx2K textures to deliver unprecedented 3D performance and image quality for the Value PC mobile market.
The 352-pin VT8231 BGA PCI-LPC bridge supports four levels (doublewords) of line buffers, type F DMA transfers and delay
transaction to allow efficient PCI bus utilization and (PCI-2.2 compliant). The VT8231 also includes an integrated Super I/O,
integrated DS12885 style real time clock with extended 256 byte CMOS RAM, integrated master mode enhanced IDE controller
with full scatter / gather capability and extension to UltraDMA-33 / 66 / 100 for 33 / 66 / 100 MB/sec transfer rate, integrated four
GUSB interface with root hub and two function ports with built-in physical layer transceivers, Distributed DMA support, integrated
AC-97 link for basic audio and HSP based modem functions, integrated hardware monitoring and OnNow / ACPI compliant
advanced configuration and power management interface. The VT8231 also has an integrated MAC and 10Mbit PHY for LAN
connection. It can bypass the internal PHY with external home PNA with a 1Mbit PHY or a 10/100Mbit PHY through the MII
.interface.
5For sophisticated power management, TwisterT provides independent clock stop control for the CPU / SDRAM and PCI and
& #Dynamic CKE control for powering down of the SDRAM. A separate suspend-well plane is implemented for the SDRAM control
%signals for Suspend-to-DRAM operation. Coupled with the VT8231 south bridge chip, a complete power conscious PC main
0 + 6 +board can be implemented with no external TTLs.
High-Performance 3D Accelerator
# * 0Featuring a new super-pipelined 128-bit engine, TwisterT utilizes a single cycle architecture that provides high performance along
with superior image quality. Several new features enhance the 3D architecture, including single-pass multitexturing, anisotropic
filtering, and an 8-bit stencil buffer. TwisterT also offers the industry’s only simultaneous usage of single-pass multitexturing and
2 ' &single-cycle trilinear filtering – enabling stunning image quality without performance loss. TwisterT further enhances image
quality with true 32-bit color rendering throughout the 3D pipeline to produce more vivid and realistic images. TwisterT’s
# & 'advanced triangle setup engine provides industry leading 3D performance for a realistic user experience in games and other
interactive 3D applications. The 3D engine is optimized for AGP texturing from system memory.
4 + 4128-bit 2D Graphics Engine
( +TwisterT’s advanced 128-bit 2D graphics engine delivers high-speed 2D acceleration for productivity applications. Several
enhancements have been made to the 2D architecture to optimize SMA performance and to provide acceleration in all color
0 7depths.
1 3DVD Playback and Video Conferencing
'TwisterT provides the ideal architecture for high quality MPEG-2 based DVD applications and video conferencing. For DVD
playback, TwisterT’s video accelerator offloads the CPU by performing the planar to packed format conversion and motion
compensation tasks, while its enhanced scaling algorithm delivers incredible full-screen video playback. For video conferencing,
TwisterT’s multiple video windows enable a cost effective solution.
LCD and Flat Panel Monitor Support
TwisterT supports a wide variety of DSTN or TFT panels through a 36-bit interface. This includes support for VGA, SVGA,
XGA, SXGA+, UXGA, and UXGA+ TFT color panels with 9-bit, 12-bit, 18-bit (both 1 pixel/clock and 2 pixels/clock), and 24-bit
interfaces. Enhanced STN hardware with 256 gray scale support and advanced frame rate control to provide up to 16.7 million
colors. In addition, the integrated 2-channel LVDS interface can support another panel. All resolutions are supported up to
1280x1024. The integrated ZV-Port allows display of video from an external source.
An alternative to the 36-bit panel interface is a 12-bit interface to a TMDS encoder. This inteface is Digital Visual Interface (DVI)
1.0 compliant.
