2.0 System Architecture
2.1 System Architecture Description
The Intel
®
IXP43X Product Line of Network Processors is a multifunction processor that
integrates the Intel XScale
®
Processor (ARM* architecture compliant) with highly
integrated peripheral controllers and network processor engines.
The processor is a highly integrated design, manufactured with Intel’s 0.13-µm
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 the many applications for which the IXP43X network
processors can be implemented. For detailed functional description, see the Intel
®
IXP43X Product Line of Network Processors Developer’s Manual.
2.2 System Memory Map
Refer to the Intel
®
IXP43X Product Line of Network Processors Developer’s Manual for
a complete memory map and register description of each individual module.
