The Intel® IXP421 network processor is a versatile single-chip processor that meets the needs of high-performance and 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 feature set integrates a 266 MHz Intel XScale core, high-performance PCI interface, USB controller, UTOPIA 2 interface, two high-speed serial (HSS) ports and one 10/100 Ethernet MAC. These features provide developers with the processing power, low power consumption, cost-effectiveness and flexibility to address the needs of data plus VoIP applications
Common IXP4XX Product Line Architecture for Application Flexibility
All IXP4XX processors have a unique distributed processing architecture that speeds development for a range of applications. Each processor combines a high-performance Intel XScale® core with additional Network Processor Engines (NPEs) to achieve wire-speed packet processing performance.
