This versatile, single-chip processor meets the needs of high performance, cost-sensitive data and Voice over IP (VoIP) applications ranging from residential gateways, Integrated Access Devices (IADs) and small office IP/PBX systems to industrial control and networked
imaging applications. The Intel® IXP421 network processor is a member of the Intel® IXP4XX product line of network processors providing cost-effective implementations that extend the rich performance and features of the Intel® IXP425 network processor into targeted market segments.
The Intel IXP421 network processor feature set integrates an Intel XScale® processor, high-performance PCI interface, USB controller, UTOPIA 2 interface, two high-speed serial (HSS) interfaces and one 10/100 Ethernet MAC. These features provide developers with processing power, low-power consumption, cost-effectiveness and flexibility to address the needs of both data and VoIP applications.
The Intel IXP421 network processor is part of Intel® Internet Exchange Architecture (Intel® IXA), a packet processing architecture that provides a foundation for software portability across multiple generations of network processors. Intel IXA is based on Intel XScale technology, the Intel IXA portability framework and programmable microengines.
