Intel® IXP42X Product Line of Network Processors and IXC1100 Control Plane Processor
2.0
Functional Overview
The Intel® IXP42X Product Line of Network Processors and IXC1100 Control Plane Processor are
compliant with the ARM* Version 5TE instruction-set architecture (ISA). The Intel® IXP42X
product line and IXC1100 control plane processors are designed with Intel 0.18-µ production
semiconductor process technology. This process technology — along with the compactness of the
Intel XScale core, the ability to simultaneously process up to three integrated network processing
engines (NPEs), and numerous dedicated-function peripheral interfaces — enables the IXP42X
product line and IXC1100 control plane processors to operate over a wide range of low-cost
networking applications, with industry-leading performance.
As indicated in Figure 1 through Figure 5, the Intel® IXP42X product line and IXC1100 control
plane processors combine many features with the Intel XScale core to create a highly integrated
processor applicable to LAN/WAN-based networking applications in addition to other embedded
networking applications.
This section briefly describes the main features of the product. For detailed functional descriptions,
