Network Proc 1.3V/3.3V 266MHz 492-Pin BGA
The Intel IXP422 network processor is a versatile, single chip processor that integrates robust security features with the necessary interfaces, wire-speed performance and processing headroom to meet demanding applications, including wireless access points, residential gateways, VPN firewall appliances, SME routers and switches, industrial control, and networked imaging applications. It 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 feature set for this network processor includes a 266 MHz Intel XScale processor, high performance PCI interface, USB controller, two 10/100 Ethernet MACs and an IPsec-enabled Network Processor Engine (NPE) to accelerate cryptography and authentication algorithmsThe Intel IXP4XX product line of network processors has a unique distributed processing architecture that speeds development for a range of applications. Each processor combines a high-performance Intel XScale processor with additional NPEs to achieve wire-speed packet processing performance The Intel XScale processor and the NPEs run their instruction streams in parallel. The processor is fully compatible with the ARM V5T Thumb instructions set and V5E DSP extensions. Designed on Intel’s 0.18-micron process technology, the processor delivers a high MIPS/power consumption ratio and provides ample processing headroom for value-added software features. The two NPEs in the Intel IXP422 network processor complement the Intel XScale processor for many computationally intensive data plane operations. These tasks include IP header inspection and modi - fication, packet filtering, packet error checking, checksum computa - tion, and flag insertion and removal. The NPE architecture includes an ALU, self-contained internal data memory and an extensive list of I/O interfaces, together with hardware acceleration elements which a set of networking applications. Each hardware acceleration element increases the speed of a specific networking task that would otherwise take many MIPS to complete by a standalone RISC processor.
