PCI Bus Interface

The PCI interface is compatible with the PCI Local Bus Specification, Rev. 2.2. It is beyond the scope of

this manual to document the intricacies of the PCI bus. This chapter describes the PCI controller

(referenced as PCI throughout this chapter) of this device and provides a basic description of PCI bus

operations. The specific emphasis is directed at how the integrated processor implements the PCI bus.

Designers of systems incorporating PCI devices should refer to the specification for a thorough description

of the PCI bus.

The PCI controller acts as a bridge between the PCI interface and the OCeaN switch fabric.

Introduction

Much of the available PCI literature refers to a 16-bit quantity as a WORD and

a 32-bit quantity as a DWORD. Because this is inconsistent with the

terminology in this manual, the terms ‘word’ and ‘double word’ are not used

in this chapter. Instead, the number of bits or bytes indicates the exact quantity.
