Accelerated Hub Architecture (AHA) (also called Intel
Hub Architecture) is an Intel 800-series chipset design that uses a dedicated
bus to transfer data between the two main processor chips instead of using
the Peripheral Component Interconnect (PCI) bus, which was used in previous
chipset architectures. The Accelerated Hub Architecture provides twice the
bandwidth of the traditional PCI bus architecture at 266 MB per second.
The Accelerated Hub Architecture consists of a memory controller hub and
an input/output (I/O) controller hub (a controller directs or manages access
to devices).
