PC 300PL Types 6584 and

6594 come with an

Intel Pentium III microprocessor. The microproce

which

has an attached heat sink,

plugs

directly into a connector

on

the system

board.

Features

The features of this microprocessor are as follows:

Ÿ

Optimization for

32-bit software

Ÿ

64-bit

microprocessor

data

bus

Ÿ

133

MHz

front

side

bus

(FSB)

Ÿ

256

KB

L2

cache integrated into the microprocessor

Ÿ

32-bit

microprocessor address bus

ŸMath coprocessor

Ÿ

MMX technology,

which

boosts the processing of graphic, video, and audio data

Ÿ

Cache speed

is half

of processor core speed

4-way set associative

Nonblocking

L2 cache

The Pentium III microprocessor provides 256 KB L2 cache. The L2 cache ECC function is enabled if ECC memory is installed. If non-ECC memory is installed, the L2 cache ECC is d information on overriding the ECC memory settings, see the chapter about the Configuratio program, inPC 300PL User Guide.) More information on this microprocessor is available at http://www.intel.com on the World Wide Web.

Chip set control

The Intel 820 chip set is the interface between the microprocessor and the following:

ŸMemory subsystem

ŸPCI bus

Ÿ

IDE bus master

connection

 

Ÿ

High-performance,

PCI-to-ISA

bridge

ŸUSB ports

ŸSMBus

Ÿ

Enhanced

DMA controller

Ÿ

Real-time

clock (RTC)
