Not all features defined by the 2.0 specification are supported for this implementation.
The following is a partial list of supported features:
The following is a partial list of features not supported:
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
processor.
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
PCI Controller
The IXP45X/IXP46X network processors’ PCI controller is compatible with the PCI Local
Bus Specification, Rev. 2.2. The PCI interface is 32-bit compatible bus and capable of
operating as either a host or an option (i.e. not the Host). This PCI implementation
supports 3.3 V I/O only.
• Six isochronous endpoints (three input and three output)
• One control endpoints
• Three interrupt endpoints
• Six bulk endpoints (three input and three output)
• Host function
• Low-speed interface
• Full-speed interface
• EHCI register interface
• Device function
• OTG function
• High-speed interface
