| Roadrunner Reference
Design for the Intel IXP23xx 
Roadrunner is a low-cost yet fully-featured,
production-ready reference platform based on the Intel® IXP2350 network processor.
Roadrunner’s broad-based software support combined and ADI's ability to quickly
design and flexibly produce custom products derived from the Roadrunner reference design
enables OEMs to get custom products to market faster, at lower cost, and with less
development risk.
Roadrunner can readily be used to deploy your
custom product functionality with application software from ADI's market-leading software
partners or by using your own Linux-based application. Optimized for low-cost and designed
for volume manufacturability, Roadrunner is available as a flexible OEM product from ADI (contact us for further details), or
in single unit quantities as a development kit with engineering support.
