Intel Hub Architecture (also called as AHA - Accelerated Hub Architecture)

Intel introduced this hub architecture starting with the 820 chipset. The hub

architecture divides control between a memory controller hub (MCH) that supports

memory and AGP and an I/O controller hub (ICH) that supports PCI, USB, sound, IDE

and LAN. The word hub in Intel Hub Architecture refers to the north and south

bridges in a chipset. Intel has replaced those two terms with the word hub.

Intel's architecture for the 8xx family of chipsets, starting with the 820. It uses a

memory controller hub (MCH) that is connected to an I/O controller hub (ICH) via a

266 MB/sec bus. The MCH chip supports memory and AGP, while the ICH chip

provides connectivity for PCI, USB, sound, IDE hard disks and LAN.
