Chipset - material

Que:- What is Chipsets? Or Explain Chipset in Motherboard? Draw and explain Chipset.
Or
Explain North bridge and South bridge in detail.
Ans:-

> Chipset is a set of electronic components in an integrated circuit that manages the

data flow between the processor, memory and peripherals.

> In other words chipset connects the microprocessor to the rest of the motherboard

and therefore to the rest of the computer. On a PC, it consists of two basic parts

the Northbridge and the Southbridge.

> All of the various components of the computer communicate with the CPU through

the chipset.
> The chipset is an integrated part of the motherboard, so it cannot be removed or upgraded.

> This means that not only must the motherboard's socket fit the CPU, the motherboard's

chipset must work optimally with the CPU.

A) North-Bridge:-
> It is also known as Memory Controller Hub.
> The northbridge connects directly to the processor via the front side bus (FSB).
> A memory controller is located on the northbridge, which gives the CPU fast access to

the memory.
> Memory buses are used to connect memory to North Bridge.
> The northbridge also connects to the AGP or PCI Express bus and to the memory itself.
> High speed performance bus is used to connect high speed devices like AGP or PCI

express devices.(e.g.Graphics Card)

B) South-Bridge:-

> The Southbridge is slower than the northbridge, and information from the CPU has to go

through the northbridge before reaching the Southbridge.

> Also known as I/O Controller Hub (because it connects all I/O to CPU)
> Internal buses are used to connect both these chips (North-bridge & South Bridge).
> Other buses connect the Southbridge to the PCI bus, the USB ports and the IDE or SATA

hard disk connections.

> Flash ROM (BIOS) and Super I/O chips are connected via LPC (low pin count) bus.
> Chipset manufacturers optimize chipsets to work with specific CPUs.
