Performing Complex Signal Processing Tasks in Networks and Telecom Infrastructure

Because they can be optimized for high-speed signal processing, our Xtensa® processors have been designed into network and telecom infrastructure devices from these companies:

NTT Docomo LTE Modem

Several Xtensa LX processors havebeen used in the LTE designs for NTT Docomo in Japan. Already, they're shipping LTE modems for notebook computers.

Cisco QuantumFlow Network Processor and ASR1000 Series Router

Cisco ASR1000

Cisco's QuantumFlow Processor consolidates 40 customized Xtensa packet processors into one piece of silicon to provide massive parallel processing. As the power behind the ASR 1000 Series Aggregation Services Router, these chips provide the processing power so additional hardware or blades are not required.

Cisco CRS-1 Carrier Router System

Cisco CRS-1

Cisco's CRS-1 uses 192 Xtensa cores per SoC. The Cisco CRS-1 seamlessly scales up to 92 terabits per second, and enables service providers to deliver the most scalable, available, and flexible converged packet infrastructure. At its highest capacity, and with the appropriate infrastructure, the CRS-1 system could run an 850Kbps connection to every household in the United States, transfer the entire collection of the U.S. Library of Congress in 4.6 seconds, or simultaneously connect three billion telephone calls.

Cisco nPower X1 Router

Cisco's nPower X1, introduced in October 2013, supports 400Gbps aggregate throughput using 336 dual-threaded Tensilica® cores. This single chip performs all the packet processing and traffic management jobs. See more information on this new chip.

DesignArt Networks Femtocell Processor

DesignArt Networks DAN2400

Multiple Xtensa processors are used by DesignArt Networks in their DAN2400 Femtocell processor. Four Xtensa processors are used for dataplane DSP and embedded control in the network processing and MAC part of this design.

One Xtensa processor is used as the powerful DSP core in the MIMO-OFDMA PHY part of this design. The Xtensa processor is used as a wide SIMD OFDM engine.

DesignArt Networks was able to use Xtensa processors to replace RTL state machines with a high-performance software-based approach.

Hughes Satellite Modem

Hughes MH900 satellite modem

Hughes Network Systems uses Xtensa processors 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.


Ikanos - VDSL Modem

Ikanos uses the Xtensa processor in their VDSL modem engine.

Ikanos architecture

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 Powerline Networking

Tensilica processors are used in powerline networking chips from Marvell. These are shipping in production volumes from a number of home powerline gear vendors including D-Link and NetGear.
