What supports high-speed devices such as cpu, memory and pci-e? A. south bridge chip B. north bridge chip C.bios chip D. I394 chip

Northbridge chip is the most important part of the motherboard chipset, also known as the host bridge. Generally speaking, the name of the chipset is named after the name of the North Bridge chip. For example, the northbridge chip of Intel 845E chipset is 82845E, and the northbridge chip of 875P chipset is 82875P. Northbridge chip is responsible for contacting CPU, controlling the transmission of memory and AGP data in Northbridge, and providing support for CPU type and main frequency, system front-end bus frequency and memory type (SDRAM, DDR SDRAM and RDRAM, etc.). ) and maximum capacity, AGP slot, ECC error correction, etc. The Northbridge chip of the integrated chipset also integrates a display core. Northbridge chip is the closest chip to CPU on the motherboard, mainly because the communication between Northbridge chip and processor is the closest, and in order to improve communication performance, the transmission distance is shortened. Because the data processing capacity of the Northbridge chip is very large, and the heat generation is also increasing, the current Northbridge chips are covered with heat sinks to enhance the heat dissipation of the Northbridge chip, and some motherboards' Northbridge chips also cooperate with fans to dissipate heat. Because the main function of the Northbridge chip is to control the memory, and the memory standard changes as frequently as the processor, the Northbridge chips of different chipsets are definitely different. Of course, this does not mean that the adopted memory technology is completely different, but there must be some differences between the Northbridge chips of different chipsets. South bridge chip is an important part of motherboard chipset, which is generally located under CPU slot and near PCI slot on motherboard. This layout is based on the fact that there are many I/O buses connected to it, and being far away from the processor is beneficial to wiring. Compared with the north bridge chip, its data processing ability is not great, so the south bridge chip generally does not cover the heat sink. The south bridge chip is not directly connected to the processor, but connected to the north bridge chip in a certain way (chipsets of different manufacturers are different, such as Intel Hub architecture of Intel and multi-threading "fun" of SIS). The South Bridge chip is responsible for the communication among I/O buses such as PCI bus, USB, LAN, ATA, SATA, audio controller, keyboard controller, real-time clock controller and advanced power management. These technologies are generally stable, so the South Bridge chip may be the same in different chipsets, but the difference is only the North Bridge chip. Therefore, the number of north bridge chips in the motherboard chipset is far more than that of south bridge chips. For example, early Intel chipsets with different architectures, such as 430TX of Socket 7 and 440LX of Slot 1, all used 823 17AB for their South Bridge chips. In recent two years, ICH7 or ICH7R southbridge chips have been used in Intel945 series chipsets, but they can also be matched with ICH6 southbridge chips. What's more, the North-South Bridge used in a few products produced by some motherboard manufacturers is the products of different chipset companies. The development direction of Southbridge chip is mainly to integrate more functions, such as comment network card, RAID, IEEE 1394, and even WI-FI wireless network.
