IXP45X and Intel
The independent NPEs and MACs allow parallel processing of data traffic on the MII interfaces
and off loading of processing required by the Intel XScale core. The IXP45X/IXP46X network
processors are compliant with the IEEE 802.3 specification.
In addition to the MII interfaces, the IXP45X/IXP46X network processors include a single
management data interface that is used to configure and control PHY devices that are connected to
the MII interfaces. The IXP45X/IXP46X network processors provide support for serial media
independent interface (SMII).
UTOPIA Level 2
The integrated UTOPIA Level 2 interface works with a network-processing engine core for several
of the IXP45X/IXP46X network processors. The pins of the UTOPIA Level 2 interface are
multiplexed with one of the MII/SMII interfaces. (See
The UTOPIA Level 2 interface supports a single- or a multiple-physical-interface configuration
with cell-level or octet-level handshaking. The network processing engine handles segmentation
and reassembly of ATM cells, CRC checking/generation, and transfer of data to/from memory.
This allows parallel processing of data traffic on the UTOPIA Level 2 interface, off-loading these
processing tasks from the Intel XScale core.
The IXP45X/IXP46X network processors are compliant with the ATM Forum, UTOPIA Level 2
Specification, Revision 1.0.
USB 1.1 Device Interface
The integrated USB 1.1 device interface supports full-speed operation and 16 endpoints and
includes an integrated transceiver.
There are:
USB 2.0 Host Interface
USB Host functionality is implemented on the IXP45X/IXP46X network processors. The function
being performed is defined by the USB 2.0 specification, maintained by usb.org and the interface is
(largely) EHCI compliant, as defined by Intel.
Not all features defined by the 2.0 specification are supported for this implementation. The
following is a partial list of supported features:
