The highly integrated, single-chip design of the Intel® IXP455 network processor provides a unique combination of performance, reliability, and flexibility, and extends Intel XScale technology into a broad range of applications that require built in communications functionality such as networking gateways, security appliances, interactive clients, test and instrumentation, RFID readers, and networked print imaging applications. The Intel IXP455 network processor is supported by a robust application development environment for the Intel IXP4XX product line. This includes pre-integrated and pre-validated development infrastructures and operating systems, development platforms, software components, and debug tools from Intel, members of the Intel® Communications Alliance, and other third-party providers.
The Intel IXP455 network processor shares a unique distributed processing architecture with the rest of the IXP4XX product line, helping to speed development for a range of applications. Each processor combines a high-performance Intel XScale core with additional Network Processor Engines (NPEs), running their instruction streams in parallel, to achieve wire-speed packet processing performance. The Intel XScale core is compliant with Intel® StrongARM* Version 5TE. Designed using Intel® 0.18-micron process technology, the core delivers a high MIPS/power consumption ratio and provides ample processing headroom for value-added software features. The three NPEs in the Intel IXP455 network processor are designed to complement the Intel XScale core for many computationally intensive data plane operations, including IP header inspection and modification, packet filtering, packet error checking, checksum computation, and flag insertion and removal. The NPE architecture includes an ALU, self-contained internal instruction and data memories, and an extensive list of I/O interfaces, together with hardware acceleration elements. The hardware acceleration elements associated with each NPE target a set of networking applications, providing an increase to the speed of specific networking tasks that would otherwise take many MIPS to complete by a stand-alone RISC processor. - - 更多 - -
