Designed Into Storage and Networking Products

Storage system architects often face the dilemma of choosing from ill-suited, general-purpose CPUs to meet the demanding functional requirements and performance goals of storage and networking applications. Because of the high processing demands on these designs, a general-purpose microprocessor (running even at several GHz) often cannot deliver the necessary horsepower within the power and cost budgets.

Because they can be optimized, Xtensa® processors have been designed into storage and networking products from many manufacturers. Some of the public ones are listed below.


Three of our licensees are publically announced, at least four are keeping it secret, and many more are in active evaluation.

LSI / Sandforce SSD Controllers

LSI Sandforce uses Cadence's Tensilica® DPUs in its market-leading SSD (solid state disk) controllers. Read about the design at Tom's Hardware.

Phison Controllers

Phison Electronics Corp. is using a Tensilica DPU in its NAND Flash memory controllers and SSD applications. Read the press release.

VIA Tek SSD Controllers

VIA is using Cadence's DPUs for a SSD SoC design. "After conducting a thorough technical evaluation, VIA determined that Tensilica's DPUs provide over four times the performance of competing processors on key algorithms used to benchmark competitive alternatives." See press release.



Cisco has multiple designs incorporating multiple Xtensa processors. Notably, their QuantumFlow and CRS Network Processors use 40 and 188 Xtensa processors, respectively.


Xtensa processors are used in their iStorage TCP/IP offload product as well as their W-CDMA Network Processor.


Xtensa processors are used in multiple product lines, more recently for PowerLine modems.


Xtensa processors are used in their Atlanta 2000 LTE Gateway.


Eight Tensilica DPUs provide protocol processing and accleration for "BladeEngine", a 10G Ethernet Controller. One DPU can be found in their "NetClient" MultiMedia client.


Xtensa processors are used in NetScreen security gateway products.


Xtensa processors are used in their VDSL modem.


Xtensa processors are used in their Satellite modem.
