1. Hardware Engineering Specification

1.1 Introduction

The E-Note P4N266A model motherboard would support the Desktop P4 processor (Northwood) at 2.0/2.2 GHz

and the Celeron low-profile, lidless FC-PGA2 (Flip-chip Pin Grid Array)package on socket 478.

This system is based on PCI architecture and is fully compatible with IBM PC/AT specification, which has

standard hardware peripheral interface and support Intel mobile Pentium 4-M and Desktop Pentium 4 family. The

power management complies with Advanced Configuration and Power Interface (ACPI) 1.0b. System also provides

icon LEDs to display system status, such as AC Power / Battery Power indicator and Battery charging status,

CDROM, HDD, NUM LOCK, CAP LOCK, SCROLL LOCK. It also equipped with 4 USB2.0 ports and 1 swap

module (Floppy or card reader or second HDD), one IEEE1394, one PC Card slots, LAN 10/100TX, MDC modem

and AC97 3D stereo audio functions.

The memory subsystem supports two 184pin DIMM socket for upgrading up to 1GB of DDR-SDRAM with

512Mbit DDR-SDRAM technology using PC-100 DDR-SDAM SODIMM modules with SPD. The DDR-SDRAM

controller supports standard PC2100 and PC1600 Synchronous DDR-SDRAM (Double-data-rate SDRAM) .

The VIA VT8703 /P4N266 /Twister-P4 (Apollo ProSavage DDR P4N266) North Bridge Chipset integrated with

S3 Savage4 graphics accelerator and S3’s flat panel interface into a single 664 BGA package. The Twister-P4 brings

mainstream graphics performance to the Value PC with leading-edge 2D, 3D and DVD video acceleration into a

cost effective package.

The Twister-P4 SMA(share memory architecture) system controller also provides superior performance between

the CPU, DRAM, and PCI bus with pipelined, burst, and concurrent operation.

The VIA 6306 controller supports three port multimedia feature.

To provide for the increasing number of multimedia applications, the AC97 CODEC VIA 1612A is integrated

onto the motherboard which contain 3D audio output.

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

and Windows 2000 and Windows XP 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.

1.2.1 CPU-Intel Desktop Pentium4(Northwood) Processor In FC-PGA478 Package

The Intel Pentium 4 processor with 512-KB L2 cache on 0.13 micron process is a follow on to the Pentium 4

processor in the 478-pin package with Intel Net Burst. microarchitecture. The Pentium 4 processor with 512-KB L2

cache on 0.13 micron process utilizes Flip-Chip Pin Grid 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 Pentium 4

processor in the 478-pin package, is based on the same Intel 32-bit microarchitecture and maintains the tradition of

Compatibility with IA-32 software. In this document, the Pentium 4 processor with 512-KB L2 cache on 0.13 micron

process will be referred to as the “Pentium 4 processor with 512-KB L2 cache on 0.13 micron process,” or simply

“the processor.”

The Intel NetBurst microarchitecture features include hyper pipelined technology, a rapid execution engine, a 400-

MHz or a 533-MHz system bus, and an execution trace cache. The hyper pipelined technology doubles the pipeline

depth in the Pentium 4 processor with 512-KB L2 cache on 0.13 micron process, allowing the processor to reach

much higher core frequencies. The rapid execution engine allows the two integer ALUs in the processor to run at

twice the core frequency, which allows many integer instructions to execute in 1/2 clock tick. The 400-MHz or 533-

MHz system bus is a quad-pumped bus running off a 100-MHz or a 133-MHz system clock making 3.2 Gbytes/sec

and 4.3 Gbytes/sec data transfer rates possible. The execution trace cache is a first-level cache that stores

approximately 12-k decoded micro-operations, which removes the instruction decoding logic from the main

execution path, thereby increasing performance. Additional features within the Intel NetBurst microarchitecture

include advanced dynamic execution, advanced transfer cache, enhanced floating point and multi-media unit, and

Streaming SIMD Extensions 2 (SSE2). The advanced dynamic execution improves speculative execution and branch

prediction internal to the processor. The advanced transfer cache is a 512 KB, on-die level 2 (L2) cache.

A new floating point and multi media unit has been implemented which provides superior performance for multi-

media and mathematically intensive applications. Finally, SSE2 adds 144 new instructions for double-precision

floating point, SIMD integer, and memory management. Power management capabilities such as AutoHALT, Stop-

Grant, Sleep, and Deep Sleep have been retained. The Streaming SIMD Extensions 2 (SSE2) enable break-through

levels of performance in multimedia applications including 3-D graphics, video decoding/encoding, and speech

recognition. The new packed double-precision floating-point instructions enhance performance for applications that

require greater range and precision, including scientific and engineering applications and advanced 3-D geometry

techniques, such as ray tracing.

The Pentium 4 processor with 512-KB L2 cache on 0.13 micron process Intel Net Burst microarchitecture system

bus utilizes a split-transaction, deferred reply protocol like the Pentium 4 processor. This system bus is not

compatible with the P6 processor family bus. The Intel Net Burst microarchitecture system bus uses Source-

Synchronous Transfer (SST) of address and data to improve performance by transferring data four times per bus

clock (4X data transfer rate, as in AGP 4X). Along with the 4X data bus, the address bus can deliver addresses two

times per bus clock and is referred to as a “double-clocked” or 2X address bus. Working together, the 4X data bus

and 2X address bus provide a data bus bandwidth of up to 4.3 G byte s/second.

Intel will enable support components for the Pentium 4 processor with 512-KB L2 cache on 0.13 micron process

including heat sinks, heat sink retention mechanisms, and sockets. Manufacturability is a high priority; hence,

mechanical assembly can be completed from the top of the motherboard and should not require any special tooling.

The processor system bus uses a variant of GTL+signalling technology called Assisted Gunning Transceiver Logic

(AGTL+) signal technology.
