What Does Accelerated Hub Architecture (AHA) Mean?
Accelerated hub architecture (AHA) is an Intel chipset design used in the 800-series family of chipsets. AHA uses a dedicated bus in order to transfer data between the two main parts of the chipset: the memory controller hub (MCH) and the I/O controller hub (ICH). The MCH supports the upper portion of the motherboard, which includes the memory (RAM) and video ports (AGP), which it interfaces to the CPU. The ICH supports the lower part of the board, which includes connectivity ports like the peripheral component interconnect (PCI), universal serial bus (USB), local area network (LAN), integrated drive electronics (IDE) and sound.
Accelerated hub architecture is also known as Intel hub architecture.
