A high-performance, multi-threaded network processor that encompasses 16 RISC-
based microengines and an embedded Intel XScale
This Quad Gigabit Ethernet MAC Controller is connected to the NPU through the
Media Access Module (for packet transmission/reception) and through the slow port
for device configuration and management. Possible IXF1104 chip configurations:
Single Quad Gigabit Ethernet PHY. Four of these devices work as a set of PHYs for
the on-board IXF1104 and are connected to this chip through the GMII interface.
The Alaska chip is configurable and manageable indirectly by the NP through the
IXF1104.
This Dual Port Gigabit Ethernet Controller is fully accessible via the PCI bus; packet
transmission/reception as well as device configuration and management. This MAC
Controller is used to support the base interface on the AdvancedTCA backplane in
the PICMG 3.1 configuration.
These components make up the Media Access Module which switches packets/cells
between IXP28x0 SPI-4 bus and four SPI-3/UTOPIA buses connected to the
following devices: on-board IXF1104 (quad Gigabit Ethernet Controller), FIC, Quad
Gigabit Ethernet Mezzanine Card, and a second Mezzanine Card (not used on
IXB2850 boards). This module is configurable through the slow port.
Two PCI bridges configurable through the PCI bus.
A 10Mb Ethernet Controller that is connected to the NPU and used for debug
purposes (console and debugger support). This chip is fully manageable (including
packet transmission and reception) through the slow port.
A dual UART device dedicated to the NPU, one used for debugger support, and one
for communication with the Board Management Controller (BMC). Note that there is
also a third UART port embedded in the IXP28x0 that is used as a NPU console.
— Base/Fabric mode - two ports used to support the fabric interface and two other
— Fabric mode - all four ports are connected to the fabric interface (two ports to
ports used for access to the base interface on the AdvancedTCA backplane
channel 1 and two ports to channel 2 or all 4 ports to channel 1)
