Overview

Pentium II

The Pentium®II Processor is the follow-on to the Pentium®Processor. The

Pentium®II Processor, like the Pentium®Pro processor, implements a Dynamic

Execution micro-architecture -- a unique combination of multiple branch prediction,

data flow analysis, and speculative execution. This enables the Pentium®II Proces-

sor to deliver higher performance than the Pentium®processor, while maintaining

binary compatibility with all previous Intel architecture processors.

A significant feature of the Pentium®II Processor, from a system perspective, is the

built-in direct multiprocessing support. In order to achieve multiprocessing, and

maintain the memory and I/O bandwidth to support it, new system designs are

needed. For systems with dual processors, it is important to consider the additional

power burdens and signal integrity issues of supporting multiple loads on a high speed

bus. The Pentium®II Processor card supports both uni-processor and dual processor

implementations.

The Pentium®II Processor utilizes Single Edge Contact (S.E.C.) (Figure 1) cartridge

packaging technology. The S.E.C. cartridge allows the L2 cache to remain tightly

coupled to the processor, while maintaining flexibility when implementing high perfor-

mance processors into OEM systems. The second level cache is performance

optimized and tested at the cartridge level. The S.E.C. cartridge utilizes surface

mounted core components and a printed circuit board with an edge finger

connection. The S.E.C. cartridge package introduced on the Pentium®II Processor

will also be used in future Slot 1 processors.

The S.E.C. cartridge has the following features: a thermal plate, a cover and a PCB

with an edge finger connection. The thermal plate allows standardized heatsink

attachment or customized thermal solutions. The thermal plate enables a reusable

heatsink to minimize fit issues for serviceability, upgradeability and replacement. The

full enclosure also protects the surface mount components. The edge finger connec-

tion maintains socketabilty for system configuration. The edge finger connector is

denoted as ‘Slot 1 connector’ in this and other documentation.

The entire enclosed product is called the Pentium®II Processor. The packaging

technology and each of the physical elements of the product are referred to using

accurate technical descriptions. This allows clear reference to the products as just a

IntroductionEP-61EXA-A

processor. This is the model used in past packaging technologies like PGA, TCP,

PQFP, DIP, etc.

S.E.C. Cartridge Terminology

• Pentium®II Processor

The new enclosed card packaging technology is called a “Single

Edge Contact cartridge.” This is similar to previous names for

packaging technology such as PGA or TCP.

• Processor card

The green PCB (with or without components on it)

• Processor core

The silicon on the PLGA package on the PCB

• Cover

The plastic cover on the opposite side from the thermal plate.

• Slot 1

The slot that the S.E.C. cartridge plugs into, just as the Pentium®

Pro processor uses Socket 8.

• Retention mechanism

Formerly ‘retention module’ the dual posts, etc. that holds the

cartridge in place.

• Thermal plate

The heatsink attachment plate.

• Heat sink supports

The support pieces that are mounted on the mainboard to provide

added support for heatsinks.

The Pentium®II Processor is the first

product to utilize the S.E.C. cartridge

technology and Slot 1 connector. Unless

otherwise noted, any references to

“Pentium®II Processor,” “Pentium®II

Processor/Slot 1 processor” or Proces-

sor” will apply to both the Pentium®II

Processor desktop processors.

Accelerated Graphics Port

(AGP or A.G.P.)

Typically, 3D graphics rendering requires a tremendous amount of memory, and

demands ever increasing throughput speed as well. As 3D products for the personal

computer become more and more popular, these demands will only increase. This

will cause a rise in costs for both end users and manufacturers. Lowering these

costs as well as improving performance is the primary motivation behind AGP. By

providing a massive increase in the bandwidth available between the video card and

the processor, it will assist in relieving some of these pressures for quite sometime.

Hardware Monitoring

Hardware monitoring allows you to monitor various aspects of your systems opera-

tions and status. These include features such as CPU temperature, voltage and fan

RPM’s.

Desktop Management Interface

(DMI)

DMI, or Desktop Management Interface, is a BIOS level method for monitoring

specific BIOS related hardware features. It allows the BIOS to collect and store

information specific to the system, so that vendors and system integrators will have

greater access to information regarding system configuration and design. This allows

for better troubleshooting, migration planning, and upgradeability decision making.

EP-61EXA-A Form-Factor

The EPoX EP-61EXA-A is designed with Micro ATX form factor - the latest

industry standard of chassis. The Micro ATX form factor is essentially a Baby-AT

baseboard rotated 90 degrees within the chassis enclosure and a new mounting

configuration for the power supply. With these changes the processor is relocated

away from the expansion slots, allowing them all to hold full length add-in cards. ATX

defines a double height aperture to the rear of the chassis which can be used to host

a wide range of onboard I/O. Only the size and position of this aperture is defined,

allowing PC manufacturers to add new I/O features (e.g.; TV input, TV output,

joystick, modem, LAN, audio, etc.) to systems. This will help systems integrators

differentiate their products in the marketplace, and better meet your needs.

•By integrating more I/O down onto the board and better positioning the hard

drive and floppy connectors material cost of cables and add-in cards is reduced.

•By reducing the number of cables and components in the system, manufacturing

time and inventory holding costs are reduced and reliability will increase.

•By using an optimized power supply, it's possible to reduce cooling costs and

lower acoustical noise. An ATX power supply, which has a side-mounted fan,

allows direct cooling of the processor and add-in cards making a secondary fan

or active heatsink unnecessary in most system applications.
