逻辑架构芯片组由北桥和南桥两颗芯片组成。

1. 北桥:
北桥是主板中朝北方向的两个芯片之一。北桥的主要函数是管理中央处理器和主板部件之间的通信。北桥直接朝向前端总线 (FSB)。北桥的其他名称是主机桥和内存控制器中心 (MCH)。

2. 南桥:
南桥是逻辑芯片组架构的另一个芯片。它位于主板中外围组件互连 (PCI) 总线的南部。南桥的主要函数是控制IO功能。
北桥是连接南桥和中央处理器的媒介。 IO 控制器集线器是南桥因其功能而获得的另一个名称。

北桥与南桥的区别:

S.NO North Bridge South Bridge
1. North bridge is located towards the north of motherboard. South bridge is located towards South of PCI bus of the motherboard.
2. North bridge is directly connected to the CPU. South bridge is connected via North bridge to the CPU.
3. It manages the communications between the CPU and other parts of the motherboard. It manages the Input and Output functions.
4. The North bridge is placed near to processor for easy access. The South bridge is placed near PCI.
5. North bridge communicates faster. South bridge communicates slower.
6. Other names for North bridge include Memory Controller Hub, host bridge. IO Controller Hub is the other name for South bridge.
7. The North bridge is hub for memory control. The South bridge is a hub for input and output functioning.
8. The North bridge connects the buses that work faster like the AGP bus. The South bridge connects the buses that work slower like ISA.
9. North bridge looks bigger. South bridge looks smaller.
10. North bridge connects components like RAM, AGP. South bridge connects components like PCI, USB.
