1. Manual Objectives
This manual describes in detail the Evalue Technology ECM-3610 Single Board.
We have tried to include as much information as possible but we have not duplicated
information that is provided in the standard IBM Technical References, unless it proved to
be necessary to aid in the understanding of this board.
We strongly recommend that you study this manual carefully before attempting to
interface with ECM-3610 or change the standard configurations. Whilst all the necessary
information is available in this manual we would recommend that unless you are confident,
you contact your supplier for guidance.
Please be aware that it is possible to create configurations within the CMOS RAM that
make booting impossible. If this should happen, clear the CMOS settings, (see the
description of the Jumper Settings for details).
If you have any suggestions or find any errors concerning this manual and want to inform
us of these, please contact our Customer Service department with the relevant details.

2.3.2 VIA VT8606 North Bridge
TwisterT (VT8606) is a high performance, cost-effective and energy efficient SMA chip set
for the implementation of mobile personal computer systems with 66 MHz, 100 MHz and
133 MHz CPU host bus (“Front Side Bus”) frequencies and based on 64-bit Socket-370
(VIA Cyrix III and Intel Celeron and Tualatin) and Slot-1 (Intel Pentium III) super-scalar
processors. TwisterT integrates VIA’s VT82C694T system controller, S3’s Savage4 2D/3D
graphics accelerator and S3’s flat panel interfaces into a single 552 BGA package. The
TwisterT SMA system controller provides superior performance between the CPU, DRAM
and PCI bus with pipelined, burst, and concurrent operation.
TwisterT supports six banks of DRAMs (three memory modules) up to 1.5Gbyte of system
memory with 256Mbit DRAM technology. The DRAM controller supports standard
Synchronous DRAM (SDRAM) and Virtual Channel SDRAM (VC SDRAM), in a flexible
mix / match manner. The Synchronous DRAM interface allows zero wait state bursting
between the DRAM and the data buffers at 100 / 133 MHz. The six banks of DRAM can
be composed of an arbitrary mixture of 1M / 2M /4M / 8M / 16M / 32MxN DRAMs. The
DRAM controller can run at either the host CPU Front Side Bus frequency (100 / 133 MHz)
or pseudo-synchronous to the CPU FSB frequency (PC100 with the FSB at 133 MHz or
PC133 with the FSB at 100 MHz) with built-in PLL timing control.

TwisterT supports a 32-bit 3.3 / 5V system bus (PCI) that is synchronous / pseudo-
synchronous to the CPU bus. The chip also contains a built-in bus-to-bus bridge to allow
simultaneous concurrent operations on each bus. Five levels (doublewords) of post write
buffers are included to allow for concurrent CPU and PCI operation. For PCI master
operation, forty-eight levels (doublewords) of post write buffers and sixteen levels
(doublewords) of prefetch buffers are included for concurrent PCI bus and DRAM/cache
accesses. The chip also supports enhanced PCI bus commands such as Memory-Read-
Line, Memory-Read-Multiple and Memory-Write-Invalid commands to minimize snoop
overhead. In addition, advanced features are supported such as snoop ahead, snoop
filtering, L1 write-back forward to PCI master, and L1 write-back merged with PCI post
writesbuffers to minimize
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.
For 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.
2.3.2.1 High-Performance 3D Accelerator
Featuring 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 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.
