Introduction
Programmer’s Guide IXP400 Software Version 2.0 April 2005
Document Number: 252539, Revision: 007 21
The IXP4XX product line and IXC1100 control plane processors have a unique distributed
processing architecture that features the performance of the Intel XScale
®
Core and up to three
Network Processor Engines (NPEs). The combination of the four high-performance processors
provides tremendous processing power and enables wire-speed performance at both the LAN and
WAN ports. The three NPEs are designed to offload many computationally intensive data plane
operations from the Intel XScale core. This provides ample “processing headroom” on the Intel
XScale core for developers to add differentiating product features. Software development is made
easier by the extensive Intel XScale core tools environment that includes compilers, debuggers,
operating systems, models, support services from third party vendors, and fully documented
evaluation hardware platforms and kits. The compiler, assembler, and linker support specific
optimizations designed for the Intel XScale microarchitecture, the ARM
*
instruction set v.5TE and
Intel DSP extensions.
