Microprocessor
The AP61 system board uses an Intel Pentium Pro (P6) processor
running at speeds of 150, 166, 180, 200 MHz or faster. Chapter 2
gives details on how to install and upgrade the Pentium processor.
ASICs
The ASICs (application-specific integrated circuits) onboard are the
Intel 82454, 82453, 82452, 82451 and Intel 82379. The Intel 82454
acts as the PCI/ISA-bus bridge that translates the PCI bus cycles. It
comes in a ball-grid array (BGA) packaging.
The Intel 82453 functions as the memory controller that supports both
the one-way and two-way interleave configurations.
The Intel 82452 serves as the memory controller data path that offers
64-bit DRAM and 32-bit PCI bus interfaces. Similar to 82454, this
chip also comes in a BGA packaging. It supports the Error Correcting
Code (ECC) feature that enables the system to correct the detected
data errors.
The Intel 82451 acts as the memory interface and the DRAM data bus
buffer.
The Intel 82379 operates as the PCI/ISA I/O controller that allows PCI
and ISA master/slave interfaces.
