3. 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.” www.ustudy.in

4. Capabilities of Chipset • Controls all I/O operation • Multiplexing • Data transfer • Memory controller • EIDE controller • PCI bridge www.ustudy.in

5. Capabilities of Chipset • DMA controller • Keyboard controller • PS/2 mouse controller • Secondary cache controller • Low-power CMOS SRAM www.ustudy.in

6. Advanced Chipset www.ustudy.in

7. 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). www.ustudy.in
