2.0 System Architecture

2.1 System Architecture Description

The Intel

IXP45X and Intel

IXP46X Product Line of Network Processors are multi-

function processors that integrate the Intel XScale

Processor (ARM* architecture

compliant) with highly integrated peripheral controllers and intelligent network

processor engines.

The processor is a highly integrated design, manufactured with Intel’s 0.18-micron

production semiconductor process technology. This process technology — along with

numerous, dedicated-function peripheral interfaces and many features with the Intel

XScale processor — addresses the needs of many system applications and helps reduce

system costs. The processors can be configured to meet many system application and

implementation needs.

Figure 2 illustrates one of many applications for which the IXP45X/IXP46X network

processors can be implemented. For detailed functional descriptions, see the Intel

IXP45X and Intel

IXP46X Product Line of Network Processors Developer’s Manual.
