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(R) IXP421 network processor is a member of the Intel(R) IXP4XX product line of network processors providing cost-effective implementations that extend the rich performance and features of the Intel(R) IXP425 network processor into targeted market segments.
The Intel IXP421 network processor feature set integrates an Intel XScale(R) 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(R) Internet Exchange Architecture (Intel(R) 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.
