Chipset

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.”

Capabilities of Chipset Controls all I/O operation Multiplexing Data transfer Memory controller EIDE controller PCI bridge

DMA controller Keyboard controller PS/2 mouse controller Secondary cache controller Low-power CMOS SRAM Capabilities of Chipset

Advanced Chipset

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 features Southbridge
