Functional Overview
The Intel
compliant with the ARM
product line and IXC1100 control plane processors are designed with Intel state-of-the-art 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
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,
see the Intel
Developer’s Manual.
