The
latter is a group of electronic components designed to perform a
specific function. For example, a modem chipset is dedicated to
receiving and transmitting data. In a PC, the chipset of the CPU
includes the central microprocessor (eg Intel Pentium circuit), and
electronic interfaces with all devices that will communicate with the
CPU clock, memory controllers, bus, peripherals etc.
It is an integrated circuit,
which has the burden of memory management, input-output at the lowest
level of operation of the computer. Intel has been a specialist chipsets
attached to its processors, but other manufacturers also make as SIS.
Where is the PC? A chipset for PC is on the motherboard (or mainboard
motherboard). It is specifically designed for a type of microprocessor
and plays an important role in the flexibility of the exchange of a
single card. The overall performance of the computer thus depend largely
on chipsets and that of the microprocessor .
What is its role? Its role is to
manage the flow of digital data between the microprocessor and the
various components and subassemblies of components of the card mother,
bus computer memory (RAM), direct memory access (DMA), Bus IDE or Serial
ATA, PCI, AGP, hard disk, network, serial port , parallel port, USB ,
FireWire, keyboard, mouse , O , graphics card , sound card,
Hyper-Threading, Front side bus, floppy drive and the input-output in
general. Some chipsets may include a graphics chip or sound chip (it
says Built-in ), which means it is not necessary to install a graphics
card or sound card. However, it is sometimes advisable to disable them
(where possible) in the BIOS setup and install expansion cards of
quality in areas designated for that purpose. (The AGP bus to the
graphics card and the PCI bus to the sound card) The Northbridge and
Southbridge chipset is not usually consists of a single circuit, but for
the older 8 and 2 in the modern circuits (Northbridge and
Southbridge).
Basically, the Northbridge is
the link between the processor and memory, while the Southbridge handles
the input / output (PCI and AGP, ...). All current manufacturers (VIA,
NVIDIA and INTEL ULI) use the same principle: a northbridge tailored to
each processor model linked to southbridges interchangeable depending on
the level of desired devices. This solution does not develop a single
circuit when changing the characteristic of a processor. Similarly, this
solution enables the manufacture of motherboards from different ranges
using different models of Southbridge.
The chipsets are the essential
components of a motherboard. That is why it is important to choose a
motherboard with integrated chipset recent opportunities to maximize
scalability of the computer. Note that the manufacturer of the chipset
may be different from the motherboard manufacturer or the microprocessor
but must be compatible.
For a complete list of PC
chipsets, see in google . In conclusion, the chipset of a motherboard
can control the exchange of information. It is often made (decomposed)
of two electronic components (elements), the Northbridge and
Southbridge. The northbridge manages exchanges between processor, memory
and video memory, and the southbridge which manages the interaction
between input / output.
