Intel® IXP420 Network Processor

The Intel® IXP420 network processor is a single-chip integrated processor that meets the needs of high-performance and cost-sensitive applications ranging from home gateways, small office/ home office (SOHO) routers and wireless access points to industrial control and networked imaging applications.
The Intel IXP420 network processor feature set integrates an Intel XScale® core, high-performance PCI interface, USB controller and two 10/100 Ethernet MACs. This network processor enables cost-effective implementations that extend the processing power, low power consumption and flexibility of the Intel® IXP425 network processor into targeted market segments. The Intel XScale core performance levels are 266 MHz, 400 MHz and 533 MHz commercial temperature and 266 MHz extended temperature.

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.
