Introduction
• The chipset is commonly used to refer to a set of
specialized chips on
a computer's motherboard or an expansion card.
• Chipsets are the main controllers on the
motherboard - they allow the CPU to interface
with the various components and expansion
cards installed.”

Northbridge
• The Northbridge of the chipset handles the
heavy traffic from one bus to another.
• Northbridge chip is responsible for interfacing
the CPU, main memory, local bus and the main
system bus.
• Northbridge supported for Memory
Technologies (64Mbit or 128Mbit SDRAM).

• The Southbridge chip handles the system’s
peripheral and I/O bus operations.
• The chip also supports a USB port and
UDMA/66 controller for hard drives.
• Southbridge supports Power management
