The IXP425 LinuxLink can also be used as a starting point for Linux development for designs derived from:
Notes:
Complete peripheral support for IXP425 derived integrated processors, or board support for other reference designs might need to be sourced from manufacturers of the respective processors or reference boards.
Processor Overview
The Intel® IXP425 network processor is a highly integrated,versatile single-chip processor that can be used in a variety of products that need network connectivity and high performance to run their unique software applications. The Intel IXP425 network processor combines integration with support for multiple WAN and LAN technologies in a common architecture designed to meet requirements for high-end gateways, Voice over IP (VoIP) applications, wireless access points, SME routers, switches, security devices, DSLAMs (Digital Subscriber Line Access Multiplexers), xDSL line cards, industrial control, and networked imaging applications.
Network Processor Engine Support
LinuxLink provides support for the Intel Network Processor Engine (NPE) featured in the Intel IXP4xx product line. Reference distributions in LinuxLink for the IXP425 include the non-crypto version of the IXP 400 Software Access Library v 2.1.1 and the IXP 400 Software NPE Microcode v 2.1. The IXP 400 software components are developed and supported by Intel and redistributed under applicable licenses by TimeSys.
