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 & networking. 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, Tensilica's Xtensa processors have been designed into storage & networking products from many manufacturers. Some of the public ones are listed below.
Two of our licensees are publically announced, 6 others are keeping it secret and many more are in active evaluation.
LSI Sandforce uses Tensilica in its market leading SSD (solid state disk) controllers. Read about the design at Tom's Hardware.
VIA is using Tensilica'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 have multiple designs incorporating multiple Xtensa processors. Notably, their QuantumFlow and CRS Network Processors use 40 and 188 Xtensa's respectively.
Used in their iStorage TCP/IP offload product as well as their W-CDMA Network Processor.
Used in multiple product lines, more recently for PowerLine modems.
Used in their Atlanta 2000 LTE Gateway
Eight Tensilica DPUs provide protocol processing and accleration for "BladeEngine", a 10G Ethernet Controller.
One Tensilica DPU can be found in their "NetClient" MultiMedia client
Used in NetScreen security gateway
Xtensa is used in their VDSL modem
Xtensa is used in their Satellite modem
