Chapter 1 General System Description

HARDWARE &SOFTWARE SPECIFICATION:

1. CPU

A. D/T INTEL P4 PROCESSOR

The Intel Pentium® 4 Processor with 512-KB L2 cache on 0.13 micron process utilizes
Flip Chip Pin Gray Array (FC-PGA2) package technology, and plugs into a 478-pin surface
mount, Zero Insertion Force (ZIF) socket, referred to as the mPGA478B socket. The Pentium 4
Processor with 512-KB L2 cache on 0.13 micron process, like its predecessor, the P4 processor
in the 478 pin package, is based on the same Intel 32-bit microarchitecture and maintains the
tradition of compatibility with 1A-32 software.

Hyper-Threading Technology is a new feature in the Intel P4 processor at 800MHz system
bus and 3.06GHz/533 MHz system bus with 512-KB L2 cache on 0.13 micron process. HT
Technology allows a single, physical P4 processor to function as two logical processors. Intel
recommend enabling HT Technology with Microsoft Windows XP Professional or Windows
XP Home, and disabling HT Technology via the BISO for all previous versions of Windows
operating system.

The Intel NetBurst microarchitecture features include hyper pipeline technology, a rapid
execution engine, a 400MHz, 533MHz, or 800MHz system bus, and an execution trace cache.
The Hyper pipeline technology doubles the pipeline depth in the P4 processor to run at twice
the core frequencies. The rapid execution engine allows the two integer ALUs in the processor
to run at twice the core frequency , which allow many integer instructions to execute in 1/2 clock
tick. The 400MHz, 533MHz, or 800MHz system bus is a quad-pumped bus running off a
100MHz or a 133MHz system clock, making 3.2Gbytes/sec, 4.3Gbytes/sec, or 6.4Gbytes/sec
data transfer rates possible.

B. MOBILE INTEL PROCESSOR

Flip-Chip Pin Grid Array (Micro-FCPGA) package with Integrated Heat Spreader, and plugs
into a surface mount, Zero Insertion Force (ZIF) socket. The Mobile Intel Pentium 4 processor
maintains full compatibility with IA-32 software.

The Intel NetBurst micro-architecture features include hyper-pipelined technology, a rapid
execution engine, a 533MHz system bus, and execution trace cache. The hyper piplined
technology doubles the pipeline depth in the Mobile Intel Pentium 4 Processor allowing the
processor to reach much higher core frequency, which allows many integer instructions to
execute in 1/2 clock tick. The 533MHz system bus is a quad-pumped bus running off a
133MHz system clock making 4.3Gbytes/sec data transfer rates possible.

The processor, when used in conjunction with the requisite Intel SpeedStep technology

applet or its equivalent, support Enhanced Intel SpeedStep technology, which enables real-time
dynamic switching of the voltage and frequency between two performance modes. This occurs
by switching the bus ratios, core operating voltage, and core processor speeds without resetting
the system. The processor features the Auto Halt, Stop Grant, Deep Sleep, and Deeper Sleep
low power states. The processor system bus uses a variant of GTL+ signaling technology called
Assisted Gunning Transceiver Logic (AGTL+) signal technology.

2. SIS648FX HMAC

performance host interface for Intel Pentium 4 processor, a high performance memory
controller, an AGP interface, and SIS MuTIOL 1G Technology connecting w/ SIS963L
MuTIOL 1G Media IO.

The SIS648FX Host Interface features the AGTL&AGTL+ compliant bus driv er technology
with integrated on-die termination to support Intel Pentium 4 series processors with PSB 400
MHz/ 533MHz/ 800MHz. It provides a 12-level In-Order-Queue to support maximum
outstanding transactions on host bus up to 12.

The Memory Controller supporting DDR only. It can offer bandwidth up to 3.2GB/s under
DDR333 in order to sustain the bandwidth demand from host processor , as well as the multi I/O
master and AGP masters. The memory Controller mainly comprises the Memory Arbiter, the
M-data/M-Command Queues, and the Memory Interface. The Memory Arbiter arbitrates a
plenty of memory access Host Controller, and I/O bus master based on a default optimized
priority list with the capability of dynamically prioritizing the I/O bus master requests in a bid
to offering privileged server to 1) the isochronous downstream transfer to guarantee the min.
latency & timely delivery, or 2) the PCI master upstream transfer to curb the latency within the
maximum tolerant period of 10us. Prior to the memory access requests pushed into the M-data
queue, any command compliant to the paging mechanism is generated and push into the
M-CMD queue. The M-data/M-CMD Queues further orders and forwards these queuing
requests to the Memory Interface in an effort to utilizing the memory bandwidth to its utm ost by
scheduling the command requests in the background when the data requests streamlines in the
foreground. The memory controller also supports the Suspend to RAM function by retaining
the CKE# pins asserted in ACPI S3 state in which only AUX source deliver power.

3. ATI M10-P VGA CHIP(NO INTER GRATED MEMORY)

achievements in the graphic industry, which enable the use of the progressive new features in
upcoming applications, but without compromising performance. ATI’s support of DirectXR9

features, highly optimized OpenGLR support, and flexible memory configurations allow

implementations targeted at the gaming enthusiast, consumer, business and workstation platforms.

Chapter 1 General System Description

10. IEEE1394 PHY

a two-port node in a cable based IEEE 1394-1995 and IEEE 1394a-2000 network. Each cable
port incorporates two differential line transceivers. The transceivers include circuitry to
monitor the line conditions as needed for determining connection status, for initialization, and
for packet reception and transmission. The PHY is designed to interface with a link-layer
controller (LLC).

The PHY require an external 24.576MHz crystal or crystal oscillator. The internal oscillator
drives an internal phase-locked loop (PLL), which generates the required 400MHz reference
signal. The 400MHz reference signal is internally divided to provide the 49.152MHz,

98.304MHz, and 196.608MHz clock signals that control transmission of the outbound encoded
strobe and data information.

When the PHY/link interface is in the disabled state, the FW802B will automatically enter a
low-power mode, if all ports are inactive (disconnected, disabled, or suspended). In this
low-power mode, the FW802B disable its PLL and also disable parts of reference circuitry
depending on the state of the ports (some reference circuitry must remain active in order to
detect incoming TP bias). The lowest power consumption (the microlow-power sleep mode) is
attained when all ports are either disconnected or disabled with the ports interrupt enable bit
cleared.

 Provides two fully compliant cable ports at 100Mbits/s, 200Mbits/s, and 400Mbits/s.

 Fully supports OHCI requirements.
