UpZide Becomes Tensilica Authorized Software Design Center; Offers Expertise in VDSL2, LTE, UWB and Baseband Chip Design

LULEA, SWEDEN and SANTA CLARA, CA -- (Marketwire) -- 01/28/09 -- Tensilica,® Inc. today announced that UpZide Technologies AB is now an authorized Tensilica Software Design Center. Over the past three years, UpZide has worked extensively on designs with Tensilica's Xtensa® customizable processors, and has strong expertise in optimizing these processors for VDSL2 (very high bit rate digital subscriber line), the most advanced standard for DSL communications. UpZide is now available to help other companies with their wireless datapath or baseband designs, including LTE (long-term evolution) and UWB (ultra wideband).

"We have expertise in optimizing Xtensa processors for performance improvements that are orders of magnitude beyond the reach of conventional processor cores for demanding dataplane tasks such as VDSL2," stated UpZide's CEO, Dr. Mikael Isaksson. "For example, a critical part of the VDSL2 design is the FFT/IFFT unit. We evaluated a top-of-the-line DSP, which showed us that each 4K transform would need approximately 370 microseconds to execute at 200 MHz clock frequency, even with highly optimized code. This is too slow for VDSL2. Using Tensilica's technology, each 4K transform needs less than 80 microseconds to execute at 200MHz -- a significant improvement that meets the VDSL2 specifications."

"UpZide has proven they can optimize Tensilica processors for complex communications algorithms, and they are a strong addition to our list of authorized software design centers," stated Chris Jones, Tensilica's director of strategic alliances.
