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. |
