Key Functional Units
The following sections briefly describe the functional units and their interaction in the system. For
more detailed information, refer to the Intel
Processors Developer’s Manual.
Unless otherwise specified, the functional descriptions apply to all of the IXP45X/IXP46X
network processors. For specific information on supported interfaces, refer to

Network Processor Engines (NPEs)
The network processor engines (NPEs) are dedicated-function processors containing hardware
coprocessors integrated into the IXP45X/IXP46X network processors. The NPEs are used to off
load processing function required by the Intel XScale core.
These NPEs are high-performance, hardware-multi-threaded processors with additional local-
hardware-assist functionality used to off load highly processor-intensive functions such as MII
(MAC), CRC checking/generation, AAL 2 segmentation and re-assembly, AES, AES-CCM, DES,
DES3, SHA-1/256/384/512, MD5, etc.
All instruction code for the NPEs are stored locally and is accessed using a dedicated instruction
memory bus. Likewise, a separate dedicated data memory bus allows accesses to local code store
as well as DDR SDRAM via the AHB bus.
These NPEs support processing of the dedicated peripherals that can include:
