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
DS2 - Powerline Networking
Tensilica's Xtensa processor is designed into DS2's 200 Mbps Aitana™ chipset for IPTV, HD Video and audio applications for the service provider and consumer home networking markets. DS2´s 200Mbps chipset delivers room-to-room HD streaming that allows consumers to instantly connect devices such as computers, HDTV´s and gaming consoles to each other over the existing home wiring. It is the market leading solution for consumer oriented HD powerline home networking products in the US and the solution of choice for self install mass market IPTV services in Europe where IPTV roll-out is very advanced. It has been selected by most service providers representing 380 million consumers including British Telecom, Telefónica, and Portugal Telecom. By simply plugging the DS2 based powerline networking devices into any electrical outlet around the home, the wires in the walls network the devices together to deliver high-definition media streaming, online gaming and next-generation digital home applications including networked security cameras, and audio and digital photo file sharing as well as service provider applications.
Here are just a handful of products that use DS2's Aitana chipset.

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-complier 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.
