As we all know, the motherboard is one of the most important components in the computer, carrying the function of the computer core running, but the realization of the motherboard function depends largely on the role of various chips on the motherboard. Many newcomers are often overwhelmed when faced with dense internal chips on computer motherboards. What are the functions of computer chips ? Which computer chip is better? Let's take a look at the decoration home decoration network Xiaobian.
What is a computer chip?
A computer chip is actually an electronic component that contains thousands of resistors and capacitors and other small components in a computer chip . There are a lot of chips on the computer. The black strips on the memory stick are chips. There are many chips on the motherboard, hard disk, graphics card, etc. The CPU is also a computer chip, but he is more complicated than the ordinary computer chip. Precision.
The computer chip is mainly concentrated on the motherboard, and also includes some peripheral chips such as a power chip, an audio chip, a cooling fan chip, and the like. The motherboard is a large place for data exchange between various hardware components inside the computer. It is like a conference room for all computer components. The motherboard can be said to have the most computer chips. Since it has to integrate a lot of basic hardware devices, there must be at least one chip at the interface of each device.
What are the functions of computer chips?
North Bridge role: North Bridge chip is responsible for the connection with the CPU and control the memory (only for Intel's cpu, AMD series cpu integrated memory controller in the cpu after K8 series, so the North Bridge chip of AMD platform does not control memory), AGP data Transmission inside the North Bridge, providing support for CPU type and frequency, system front-side bus frequency, memory type (SDRAM, DDR SDRAM, RDRAM, etc.) and maximum capacity, AGP slot, ECC error correction, integrated chip The group's Northbridge chip also integrates the display core.
South Bridge role: South Bridge chip is responsible for communication between I / O bus, such as PCI bus, USB, LAN, ATA, SATA, audio controller, keyboard controller, real-time clock controller, advanced power management, etc. Relatively stable, so the south bridge chip may be the same in different chipsets, the only difference is the Northbridge chip. So now the number of Northbridge chips in the motherboard chipset is much larger than the Southbridge chip. For example, the early Intel Intel chipset Socket 7 430TX and Slot 1 440LX have adopted the 82317AB, while the chipset 845E/845G/845GE/845PE has adopted the ICH4 South Bridge chip in the past two years. Can be used with the ICH2 South Bridge chip. The development direction of the South Bridge chip is mainly to integrate more functions, such as network card, RAID, IEEE 1394, and even WI-FI wireless network.
Which computer chip is better?
Computer chips mainly include CPU (Central Processing Unit) chip, BIOS chip, CMOS chip, chipset (including South Bridge and North Bridge), MCH (Memory Controller Center), ICH (Input/Output Controller Center), FWH (Firmware Control) ), I/O chips, integrated graphics chips, integrated network card chips, integrated sound card chips, and more.
1, power management chip: power management chip, also known as power IC, also known as pulse width modulation chip (PWM), the motherboard is called: programmable pulse width modulation chip, mainly responsible for controlling the main power supply of the CPU, generally located near the CPU socket, Look at the model identification.
2, I / O chip: I / O chip is mainly responsible for controlling the software drive, print port, keyboard mouse port. Common I/O chips are W83627HF, IT8712F, and IT8705F. These three chips integrate monitoring functions. Others integrate power management functions (but cannot control the main power supply) such as W83627F/TF/EF, W83697F, and IT8712F. IT8702F, 8671F.
3, serial chip: serial port chip is responsible for controlling the serial port (COM port) on the motherboard, common models million GD75232, GD75185, HT6571, IT8687R, the first three are 20 pins, one chip is responsible for managing a serial port; IT8687R is 48 pins, one chip Manage two serial ports at the same time.
4. Clock chip: The clock chip is connected with the 14.318 crystal oscillator, which is the source of the clock signal for all devices on the motherboard. The clock chip provides frequency to all devices on the motherboard. (Based on the frequency of the clock crystal, the frequency is superimposed and divided, and provided to other devices on the motherboard, PCI, AGP, memory, CPU). The clock chip is controlled by the south bridge, and the common model ICSXXX, the clock chip and the clock crystal are connected together.
5, sound card chip: onboard sound card generally has a soft sound card and hard sound card. The soft and hard points here refer to whether the onboard sound card has the main processing core of the sound card. Generally, the soft sound card has no main processing chip, and only one decoding chip replaces the function of the main processing chip of the sound card by the operation of the CPU; The sound card has a main processing chip, and many audio processing jobs no longer require CPU involvement. Common models are ALC101, ALC655, VIA1616, CMI9739A, CMI8738 and so on.
6. NIC chip: The motherboard NIC chip refers to the NIC chip integrated by the motherboard integrated with the network function. Correspondingly, there is also a corresponding NIC interface (RJ-45) on the backplane of the motherboard. Common models are RTL8100C, VT6103, 3COM, etc.
7, BIOS chip: basic input and output system, is a shorthand for the basic input and output system of read-only memory, it is actually a group is solidified in the computer, providing the computer with the lowest level of the most direct hardware control program, it is connected software program and The hub between hard disk devices. The BIOS chip is a flat-type or rectangular chip on the motherboard.
8, RAID chip: RAID Chinese is referred to as a redundant array of modest disks. RAID is a redundant array of multiple hard disks. Although RAID contains multiple hard drives, it appears as a separate large storage device under the operating system.
9, boot reset chip: General ASUS motherboard and MSI motherboard have this chip, ASUS motherboard chip model is AS99127F, AS97127F, MSI motherboard chip model is MS-5, 2310GE.
10, logic signal control chip: also known as overclocking protection chip, model is Attansic ATXP1, 48 pin, this chip can control the voltage can also be divided, while supporting PCI frequency lock.
The above is what is the role of computer chips brought to you by Xiaobian? Which computer chip is better? I believe that everyone has a basic understanding of the role of computer chips after reading this article.
