Overview
AMD AthlonTM Processor
The AM AthlonTM processor is the newest microprocessor in the AM K86TM
family of microprocessors. The AM Athlon processor brings superscalar RISC
performance to desktop systems running industry-standard x86 software. This
processor implements advanced design techniques such as:
 Three out-of-order, superscalar, pipelined Multimedia Units
 Three out-of-order, superscalar, pipelined Integer Units
 Three x86 instruction decoders
 Fixed-sized internal instruction formats (MacroOPs)
 72-entry Instruction Control Unit
 AM 3 NOW!TM technology
 Large L1 and L2 caches and translation lookaside (TLB) structures
 Register renaming and data-forwarding
 ynamic branch prediction
 S2K Interface Technology
The AM Athlon processor is the first x86 processor ever to incorporate the S2K
interface technology to deliver unprecedented system performance. The S2K
interface technology is based on the EV6 bus technology from igital/Compaq
and provides 1.6 Gbytes per second bandwidth to the system.
The AM Athlon Processor utilizes Single Edge Contact (S.E.C.) (Figure 1)
cartridge packaging technology. 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 AM Athlon Processor will also be
used in future Slot A 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

IntroductionEP-7KXA

heatsink to minimize fit issues for serviceability, upgradeability and replacement.
The full enclosure also protects the surface mount components. The edge finger
connection maintains socketabilty for system configuration. The edge finger
connector is denoted as Slot A connector in this and other documentation.
S.E.C. Cartridge Terminology
 Processor card
The green PCB (with or without components on it)
 Processor core
The CPU silicon chip on the processor card.
 Cover
The plastic cover on the opposite side from the thermal plate.
 Slot A
The slot that the S.E.C. cartridge plugs into.
 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.

Accelerated Graphics Port
(AGP or A.G.P.)
Typically, 3 graphics rendering requires a tremendous amount of memory, and
demands ever increasing throughput speed as well. As 3 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
operations and status. The features include CPU temperature, voltage and RPM of
fan.

EP-7KXA Form-Factor
The EP-7KXA is designed with ATX form factor - the new industry standard of
chassis. 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, etc.) to systems. This will help systems integrators differentiate their
products in the marketplace, and better meet your needs.
 Smaller size promotes a smaller system size.
 I/O shield does not need to be retooled in an ATX 2.01 or later. The
mainboard should be used in an ATX 2.01 (or later) compliant case.
 A smaller power supply can be used. High integration on mainboard
reduces the system costs.

Power-On/Off (Remote)
The EP-7KXA has a single 20-pin connector for ATX power supplies. For ATX
power supplies that support the Remote On/Off feature, this should be connected
to the systems front panel for system Power On/Off button. The systems power
On/Off button should be a momentary button that is normally open.
The EP-7KXA has been designed with Soft Off" functions. You can turn Off the
system from one of two sources: The first is the front panel Power On/Off
button, and the other is the "Soft Off" function (coming from the EP-7KXAs
onboard circuit controller) that can be controlled by the operating system.
Windows 95/98 will control this when the user clicks that they are ready to
Shutdown the system.
