Designed Into Network Access Products

Because they can be optimized for network processing, Tensilica's Xtensa processors have been designed into network access devices from these companies:

See the presentation given at the Linley Group Tech Seminar - CPU Cores and IP for Networking, January 31, 2007, Networking Applications for Xtensa Configurable Processors.

NTT Docomo LTE Modem

Several Tensilica Xtensa LX DPUs are being used in the new LTE designs for NTT Docomo in Japan. Already they're shipping LTE modems for notebook computers.

Later in 2011 handsets for the LTE network will start shipping. See press release.

DesignArt Networks Femtocell Processor

Multiple Xtensa DPUs are used by DesignArt Networks in their DAN2400 Femtocell processor. Four Xtensa DPUs are used for dataplane DSP and embedded control in the Network Processing and MAC part of this design. One Xtensa DPU is used as the powerful DSP core in the MIMO-OFDMA PHY part of this design. The Xtensa DPU is used as a wide SIMD OFDM engine. DesignArt Networks was able to use Xtensa DPUs to replace RTL state machines with a high-performance software-based approach.

Hughes Satellite Modem

Hughes Network Systems uses Tensilica's DPUs in their HN9000 satellite modem. It is used primarily for satellite broadband access in rural market areas. This is a 7-core Xtensa design with cores used for control, uplink layer 1 and layer 2 processing, and downlink layer 1 and layer 2 processing. The HN9000 is a high-perofrmance broadband modem that provides broadband services utilizing the unique high-capacity SPACEWAY 3 satellite system. This modem delivers throughputs up to 1 Mbps on the uplink and up to 5 Mbps on the downlink.

Ikanos - VDSL Modem

Ikanos uses the Xtensa processor in their VDSL modem engine. Anoop Khurana, Ikanos Communications’ Vice President of Engineering, said, “We have evaluated a number of emerging processor technologies, and we decided upon Tensilica’s configurable Xtensa architecture because it offers a comprehensive solution, including synthesizable RTL of the processor, 166-200Mhz performance range, an automatically generated C-compiler and cycle accurate instruction set simulator, and Wind River support. We were specially impressed with the Tensilica Instruction Extension (TIE) methodology, and the performance improvements achievable through the use of the TIE compiler."

Ikanos uses Xtensa inside the SmartLeap VDSL products.

The SmartLeap chipsets are used in up to 72-port line cards for Multi-mode VDSL2, VDSL, VDSL Long Range (VLR), ADSL2+, and ADSL based Broadband Access Concentrators, Remote Units, Mini-RAMs, ATM and IP DSLAMs.

Marvell's Net-GX IPSec Accelerator Engine

Marvell's products featuring Tensilica's Xtensa processors include:

• Yukon EC 88E8050 PCI Express Gigabit Ethernet Controller
• Link Street 88E6318 IPSec VPN Gateway Router
• Horizon GT-96122 and GT-96132 Communications Controllers
• Horizon MV96360/MV96340 Communications Controllers

Marvell says that the Marvel NetGX co-processor is used across a number of Marvell products, and is fully optimized by Marvell, through the use of TIE instructions, to carry packet processing applications.
