3 / 4 page Features s Four high-performance processors in a distributed processing architecture s Highly-integrated data/voice/security functions s Broad range of WAN/LAN capabilities s Development Platform s Commercial and Extended temperature options Benefits s Wire-speed performance; Able to offer rich data, voice and security services s Reduced chip count; Cost savings; Simplified design s Flexibility; Common architecture for multiple platforms s Faster time-to-market s Flexibility 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. |
