UpZide Becomes Tensilica Authorized Software Design Center

“We have extensive 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 deep expertise in designing state-of-the-art datapaths with Tensilica’s technology,” stated Chris Jones, Tensilica’s director of strategic alliances. “UpZide has proven that they can optimize our processors for complex communications algorithms, and we are excited to add them to our list of authorized software design centers.”
