1. Hardware Engineering Specification

1.1 Introduction

The 8575A motherboard would support the Intel® Pentium® 4 processor with FC-PGA2 packaged, using

478-Pin micro PGA (mPGA478) socket, which will supports different speeds up to Willamette P4 1.7GHz

(Throttling)/Northwood above 2.0GHz (Throttling).

The memory subsystem supports 0MB on board memory, two JEDEC-standard 200-pin, small-outline, dual

in-line memory module (SODIMM), support PC2100 & PC2700.

This system is based on PCI architecture, which have standard hardware peripheral interface. The power

management complies with Advanced Configuration and Power Interface (ACPI) 1.0. It also provides easy

configuration through CMOS setup, which is built in system BIOS software and can be pop-up by pressing

F2 at system start up or warm reset. System also provides icon LEDs to display system status, such as power

indicator, HDD/CDROM, NUM LOCK, CAP LOCK, SCROLL LOCK, SUSPEND MODE and Battery

charging status. It also equipped 2 USB ports.

SiS650 IGUI Host Memory Controller integrates a high performance host interface for Intel Pentium 4

processor, a high performance 2D/3D Graphic Engine, a high performance memory controller, an AGP 4X

interface, and SiS MuTIOL® Technology connecting w/ SiS961 MuTIOL® Media I/O.

The SiS961 MuTIOL® Media I/O integrates the Audio Controller with AC 97 Interface, the Ethernet MAC,

the Dual Universal Serial Bus Host Controllers, the IDE Master/Slave controllers, and the MuTIOL® Connect

to PCI bridge. The PCI to LPC bridge, I/O Advanced Programmable Interrupt Controller, legacy system I/O,

I/O Advanced Programmable Interrupt Controller and legacy power management functionalities are also

integrated. The SiS961 also incorporates an universal interface supporting the asynchronous inputs/outputs of

the X86 compatible microprocessors like P4.

The SiS301LV is a Display device which has two data operation paths. Channel B path is selected when

SiS301LV performs TV or LCD only display function. There’s scaling hardware in this path. In LCD display

mode, this hardware can make lower VGA resolution display to fit up to 1280x1024 LCD panel. In TV display

mode, this scaler can provide overscan and underscan option for TV. At TV and LCD simultaneous display

mode, TV data stream run through Channel B and LCD data stream run through Channel A.

To provide for the increasing number of multimedia applications, the AC97 CODEC ALC201 is integrated

onto the motherboard.

A full set of software drivers and utilities are available to allow advanced operating systems such as Windows

Me and Windows 2000 to take full advantage of the hardware capabilities such as bus mastering IDE, Windows

95-ready Plug & Play, Advanced Power Management (APM) and Advance configuration and power interface

(ACPI).

Following chapters will have more detail description for each individual sub-systems and functions.

Built on 0.13-micron process technology and Intel® NetBurst™ micro-architecture, the Mobile Intel®

Pentium® 4 Processor - M represents a new generation of mobile computing. It provides superior capabilities

for graphics-intensive multimedia applications, and processor-intensive background computing tasks such as

compression, encryption, and virus scanning. Enhanced Intel® SpeedStep® technology helps to optimize

application performance and power consumption, and Deeper Sleep Alert State, a dynamic power management

mode, adjusts voltage during brief periods of inactivity - even between keystrokes - for longer battery life.

Innovative Micro FCPGA packaging technology enables the processor to fit into small form factors, such as

thin-and-light notebooks.

The Intel® Pentium® 4 processor, Intel’s most advanced, most powerful processor, is based on the new Intel®

NetBurst™ micro-architecture. The Pentium 4 processor is designed to deliver performance across applications

and usages where end users can truly appreciate and experience the performance. These applications include

Internet audio and streaming video, image processing, video content creation, speech, 3D, CAD, games, multi-

media, and multi-tasking user environments. The Intel Pentium 4 processor delivers this world-class

performance for consumer enthusiast and business professional desktop users as well as for entry-level

workstation users.

a number of enhanced features Advanced Transfer Cache, Advanced Dynamic Execution, Enhanced Floating-

point and Multi-media Unit, and Streaming SIMD Extensions 2. Many of these new innovations and advances

were made possible with improvements in processor technology, process technology, and circuit design that

could not previously be implemented in high-volume, manufacturable solutions. The features and resulting

benefits of the new micro-architecture are defined below.

Intel Pentium 4 Processor Product Feature Highlights

8575A N/B Maintenance

A N/B Maintenance

Hyper Pipelined Technology:

The hyper-pipelined technology of the NetBurst micro-architecture doubles the pipeline depth compared to

the P6 micro-architecture used on today’s Pentium III processors. One of the key pipelines, the branch

prediction/ recovery pipeline, is implemented in 20 stages in the NetBurst micro-architecture, compared to

10 stages in the P6 micro-architecture. This technology significantly increases the performance, frequency,

and scalability of the processor.

400 MHZ System Bus:

The Pentium4 processor supports Intel’s highest performance desktop system bus by delivering 3.2 GB

of data per second into and out of the processor. This is accomplished through a physical signaling scheme

of quad pumping the data transfers over a 100-MHz clocked system bus and a buffering scheme allowing

for sustained 400-MHz data transfers. This compares to 1.06 GB/s delivered on the Pentium III processor’s

133-MHz system bus.

Level 1 Execution Trace Cache:

In addition to the 8KB data cache, the Pentium 4 processor includes an Execution Trace Cache that stores

up to 12K decoded micro-ops in the order of program execution. This increases performance by removing

the decoder from the main execution loop and makes more efficient usage of the cache storage space since

instructions that are branched around are not stored. The result is a means to deliver a high volume of

instructions to the processor’s execution units and a reduction in the overall time required to recover from

branches that have been mis-predicted.
