Highly-integrated Data, Voice, and
Security Functionality
On-chip integration of data, voice, and security functions
saves the cost of implementing separate devices and
supports easier integration with other hardware. Integrated
into the Intel XScale core are multiply and accumulate
functions that give customers the ability to do multimedia
processing without the need for external hardware. For
example, in a voice application, the Intel XScale core can
perform a wide variety of speech coding and telephony
algorithms without the need for an external DSP chip. In
addition, the network processors integrate two 10/100
Base-T Ethernet MACs with MII/RMII interface and simul-
taneous full-duplex operation. To further reduce the total
solution chip count, a SDRAM controller has been inte-
grated along with peripheral functions that include interrupt
controller, GPIO port, UART, watchdog timer and general-
purpose timers. A USB version 1.1 device controller is
integrated for those applications that require USB sup-
port. The Intel IXP425 network processors also provide
hardware acceleration for security applications. These
chips implement, in hardware, DES and 3DES data
encryption algorithms as well as SHA-1 and MD5
hashing algorithms typically used in VPN applications.
A direct connection to DSP chips and flash memory is
achieved through the expansion bus interface. By
integrating more functionality, Intel is reducing the total
solution chip count and cost for broadband applications.
Broad Range of LAN and WAN Capabilities
The Intel IXP425 network processors offer a full range of
broadband and LAN access solutions through multiple
integrated interfaces. Through the UTOPIA 2 interface,
there is performance to support up to eight ADSL PHYs,
eight G.SHDSL PHYs or one VDSL PHY. The PCI ver-
sion 2.2 Host and Option interface gives customers the
flexibility to directly connect such devices as 802.11x
chips, PCMCIA controllers, Ethernet MACs, and cable
MAC/PHYs. These network processors also feature
two high-speed serial interfaces. These interfaces can
serve as high-speed ports for direct connection to
T1/E1 framers or to industry-standard SLIC/CODECS.
Choice of Tools and Operating Systems Supports
Rapid Development
The Intel XScale microarchitecture offers a broad range
of tools together with support for two widely adopted
operating systems. The Intel IXP425 network processors
support VxWorks and the standard Linux 2.4 kernal.
MontaVista Software* will provide the support for Linux.
To help speed time-to-market and reduce development
costs, developers will have a wide choice of third-party
tools, including compilers, linkers, debuggers and
board support packages (BSPs). Tools include Wind
River* Tornado* 2.1.1 for the VxWorks 5.4 real-time
operating system, and the complete GNU* Linux
development suite.
Development Platform For Faster Time-to-Market
The Intel
IXDP425 Network Processor Development
Platform is a powerful tool for developing and verifying
hardware and software for the Intel IXP425 network
processors. Developers can use this flexible and extend-
able platform to conduct rapid initial chip evaluation,
chip performance evaluation, product development
and prototyping. For additional information, refer to the
Intel IXDP425 Development Platform product brief.
