Intel IXP435
The LinuxLink software distribution model enables the usage of the IXP435 LinuxLink for development targeting all designs based on IXP435 processor or similar processors in the IXP4xx family.
Processor derivatives enabled:
The IXP435 LinuxLink can also be used as a starting point for Linux development for designs based on the IXP433, IXP432, IXP431, IXP430 processors.
Reference boards/OEM boards enabled:
The IXP435 LinuxLink has been developed using Intel's KIXRP435 Multi-Service Residential Gateway Reference Platform. It can also be used as a starting point for Linux development for designs derived from the Novatec NTNP435C.
Notes:
Complete peripheral support for IXP435 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® IXP43X Product Line of Network Processors is positioned to enable both cost-sensitive Gateways and Converged Access Platforms (CAP). The platform has integrated SLIC codecs and DAA circuitry for VoIP and Philips PNX1702 Nexperia media processor to support media centric applications such as triple-play.
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 IXP435 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.
